There are about 1.5 gallons (or 5.5 liters) of blood in the average adult body. Blood regenerates every second. Two million new red blood cells per second, for accuracy. We all know that the circulatory system carries oxygen throughout the body. But did you know that it also carries electrolytes, carbon dioxide, hormones and amino acids? The blood consists of red blood cells, white blood cells, platelets and plasma. The circulatory system is closely linked to the lymphatic system. The lymphatic fluid is the plasma that has filtered through the body and returned to the lymphatic system. The circulatory system is subject to cardiovascular diseases. For example, stroke, hypertension and heart failure affect these areas. Healthy nutrition, exercise and limitation of tobacco and alcohol intake prevent such conditions. Some conditions, such as high and low pressure, are hereditary. It is important to know your family history. ? Tell your doctor about any history of heart problems. The circulatory system is the complex network responsible for the supply of nutrients, hormones and gases such as oxygen to body cells. This system, also known as the cardiovascular system, works in tandem with other body systems to maintain homeostasis ? the ability of the body to maintain stability despite continuous changes ? and is an integral part of many of the functions that allow the body to thrive. The essential parts of the circulatory system are blood, blood vessels and heart, although many secondary components contribute to maintaining the functioning system. For explanation, educators often say that the circulatory system "initiates" in the right atrium. Actually, if the body works properly, the system does not start or end anywhere. Each part of the system works simultaneously. The right atrium in the upper right of the heart receives deoxidised blood through two large veins. The upper quarry vein accepts blood from parts of the body as the head and arms. The lower vein accepts blood from the legs and the lower abdomen. wetcake / Getty Images In the right atrium wall there is a group of cells that control heart contractions. This ventrial node sends electric pulse controls the heart and pushes the blood from the right atrium into the right ventricle. Before entering the right ventricle, it must pass through the tricuspid valve, which prevents reflux. Once the blood enters the right ventricle, the atrioventricular node regulates the speed with which the blood flows to prevent the ventricle from contracting without a sufficient level of blood. The two knots that work together make the heart beat and allows the blood to move around the circulatory system. Thomas-Soellner / Getty Images Deoxidised blood must return to the lungs forMore oxygen. During pulmonary circulation, the right ventricle contracts to send blood through the pulmonary valve in the pulmonary artery. The pulmonary valve is responsible for us Blood runs only in the artery and not again in the ventricle. Pulmonary artery connects to a multitude of others, small arteries and capillaries to deliver blood to the pulmonary alveoles in the lungs. Pattanaphong Khuankaew / Getty Images The pulmonary alveoli are small, empty cavities in the lungs. When we inal, the alveoli absorb oxygen from the air. The capillaries surrounding these cavities allow the exchange of gas between the alveoli and the blood. Carbon dioxide comes out of blood and enters the alveoli and oxygen travels from the alveoli to the blood. When the lungs exhale, they release carbon dioxide from the body and the process starts again. This is an example of the circulatory system that works together with the respiratory system. dimuratdeniz / getty Images Now that blood is full of oxygen, must deliver that oxygen during the rest of the body. To do this, the heart is opposed to pull blood from the pulmonary alveoles in four veins, two for each lung. Blood travels through these four pulmonary veins and fills the left atrium of the heart. After this process, the body begins to transfer oxygen to the rest of the body. Magic / getty Images The left ventricle is the largest of the four rooms of the heart. Because of this, it is also able to provide the highest pressure to move the blood around the body. Blood travels through the mitral valve from the left atrium and starts filling the left ventricle. When the left ventricle prepares to expel the blood to the rest of the body, the mitral valve closes, due to the pressure difference. The ventricle then pushes the blood to the aorta. Tefi / Getty Images The Aorta is the main artery, located just above the heart. As you travel along the abdomen, you have fun in two separate and smaller arteries. The blood moving from the left ventricle passes through the aortic valve before entering the aorta. From there, he flows towards the smaller arteries and capillaries that spread throughout the human body. However, before the blood can reach capillaries, it must travel through small blood vessels called arterioli. The arterioles change diameter to adjust blood pressure and speed. StandardAls / Getty Images The pressure and speed adjustments of the arterile functions allow a constant exchange of gases, nutrients and other blood content to the cells. Blood transfers oxygen and nutrients into cells and receives carbon dioxide and other waste materials. After the blood loses its oxygen, it must return to the heart so that the process can start over. First, he enters blood vessels similar to the arteriole venules. From the venules, the blood pours into the veins themselves. OLEGUSMANOV / Getty Images The veins can be considered the opposite of the arteries as they bring blood to the heart rather than far from it, even if the veins are less Most veins have valves that prevent blood outflow. The veins of the arms and the head connect to connect The superior vena cava while the veins from the legs and abdomen connect to the inferior vena cava. Blood returns to the right atrium, and the circulatory system restarts. Belchonock / Getty Images It is important to remember that the circulatory system never ends, as long as the body is healthy. All processes occur simultaneously and the blood never stops flowing. When the system is broken up, its complex parts can be easy to remember and understand. The circulatory system is the combined efforts of systemic circulation and pulmonary circulation. Systematic circulation. Systematic circulation provides organs, tissues and cells with oxygenated blood. The thoughtful circulation is where the blood receives its oxygen and releases carbon dioxide. The circulatory system is an E cycle ending with the heart.Colematt / Getty Images The heart is crucial to life and the focus of love. Explore the parts of the heart and how your heart works, as well as take a look at real pictures of human hearts with this gallery. Creatinine is a chemical molecule found in the serum (liquid portion) of the blood. The amount of creatinine produced depends on a person's muscle mass. But how is it measured? By Jill FergusonWhen you accidentally cut yourself, do you ever wonder what makes up for this thing we call blood? It's a pretty amazing stuff, considering how it targets infections while providing nutrients to every cell in the human body.By Carl Bianco, M.D.The heart is a vital organ that functions fundamentally as a pump. Discover the heart chambers and valves, the blood flow, the heart's electrical system and blood flow. Read more about how this amazing organ works.by Carl Bianco, M.D. Let's see and hear hearts everywhere. A long time ago, people even thought that their emotions came from their hearts, perhaps because the heart beats faster when a person is scared or excited. Now we know that emotions come from the brain, and in this case, the brain tells the heart to speed up. So what's the heart up to, then? How do you keep busy? What does it look like? Let's find out. The heart is a muscle that your heart is really a muscle. It is located a little to the left of the center of your chest, and is about the size of your fist. There are many muscles on your body ? ?" between your arms, in your legs, in your back, even in your back. But the heart muscle is special because of what it does. The heart sends blood around your body. Blood provides your body with the oxygen and nutrients it needs. Bring the garbage, too. Your heart is sort of a pump or two pumps in one. The right side of your heart receives blood from your body and pumps to your lungs. The left side of the heart has the exact opposite: it receives blood from the lungs and pumps it out to the body. How the heart beats like the heart beats? of every beat, your heart fills with blood. So his muscle contracts to splash blood. When the heart contracts, it crushes ? try try try Hand in a fist. This is a bit like the one carried out by the heart so it can splash blood. Your heart does this all day and all night, all the time. The heart is a hard worker! Page 1 Parts of the Heart The heart consists of four different areas filled with blood, and each of these areas is called a chamber. There are two rooms on each side of the heart. One room is on the top and one room is on the bottom. The two rooms above are called atri (say: AY-tree-uh). If you're talking about just one, call an atrium. The atria are the chambers that fill up with blood returning to the heart from the body and lungs. The heart has a left atrium and right atrium. The two chambers on the bottom are called ventricles (do: VEN-trih-K?1/4lz). The heart has a left ventricle and a right ventricle. Their task is to splash blood to the body and lungs. Running in the middle of the heart is a thick wall of muscles called the septum (say: SEP-tum). The work of the septum is to separate the left side and the right side of the heart. The atria and ventricles work as a team is filling atria with blood, then dump into the ventricles. The ventricles then squeeze, pump blood from the heart. While the ventricles are compressing, the atria recharge and prepare for the next contraction. So, when the blood is pumped, how does he know which way to go? Well, your blood is based on four special valves inside your heart. A valve leaves something and keeps it there closing a thought of walking through a door. It closes the door behind you and prevents you from going backwards. Two of the heart valves are the mitral (say: MY-Trul) of the valve and the tricuspid (say: try-KUS-PID) of the valve. They left the blood flow from the atria to the ventricles. The other two are called the "aortic (say: ay-O-tik) valve and pulmonary (say: PUL-muh-ner-ee) valve, and are responsible for controlling the flow as the leaves of blood to the heart. These valves all work to keep the blood flowing forward. They open to allow blood to pass forward, then close quickly to keep blood flowing backwards. Page 2 How Blood Circulates You probably guessed that blood just doesn't slosh your body once it leaves your heart. It moves through many tubes called arteries and veins, which together are called blood vessels. These blood vessels are attached to the heart. The blood vessels that carry blood from the heart are called arteries. Those that bring blood back to the heart are called veins. The movement of blood through the heart and throughout the body is called circulation (e.g.: sur-Kyoo-LAY-shun), and your heart is really good at doing so it takes less than 60 seconds to pump blood to every cell in your body. Your body needs this constant supply of blood for proper functioning. Blood carries oxygen to all cells in the body. To stay alive, a person needs healthy, living cells. Without oxygen, these cells would have died. If this oxygen-rich blood doesn't circulate as it should, it should, The person could die. The left side of your heart sends that blood rich in oxygen to the body. The body removes oxygen from the blood and uses it in body cells. When cells use oxygen, carbon dioxide and other things that are brought away from the blood. It's like the blood deliver lunch to the cells and then take the garbage! The return blood enters the right side of the heart. The right ventricle pump the blood to the lungs for a little refreshment. In the lungs, carbon dioxide is removed from the blood and sent from the body when we exhale. What's next? An inhalation, of course, and a fresh breath of oxygen that can enter into the blood to start the process. And remember, everything happens in about a minute! Page 3 Listen to lub-dub when you go for a check, your doctor uses a stethoscope to listen to your heart carefully. A healthy heart makes a lub-dub sound with every beat. This sound comes from the valves that close on the blood inside the heart. The first sound (LUB) takes place when the mitral and trichuspid valves close. The next sound (dub) takes place when the aortic and pulmonary valves close after the blood was pressed by the heart. Next time go to the doctor, ask if you can also listen to Lub-dub. Figo enough ? oeIt is my impulse! Even if your heart is within you, there is a cool way to know that it is working from the outside. It's your wrist. You can find the wrist by pressing lightly on the skin wherever there is a great artery that runs right under your skin. Two good places to find it are on the side of the neck and the inside of the wrist, just below the thumb. You will know that you have found your wrist when you can hear a small beat under the skin. Every beat is caused by the contraction of your heart. If you want to find out what your heart rate, use a watch with a second hand and count how many beats you feel in 1 minute. When you are resting, you will probably feel between 70 and 100 beats per minute. When you run a lot, the body needs much more blood filled with oxygen. Your heart pumps faster to supply blood filled with oxygen whose body needs. You could also feel your heart that beats you in your chest. Try running in place or skip the rope for a few minutes and take the wrist again ? "Now how many beats accounts in 1 minute? Keep your heart happy Most children were born with a healthy heart and it is important to keep your in good shape. Here are some things you can do to help keep your heart happy: remember that your heart is a muscle. If you want it to be strong, you have to practice it. How are you? Being active in a way that makes you vomit and inflate, how to skip the rope, dance, or play basketball. Try to be active every day for at least 30 minutes! An hour would be Better for your heart! Eat a variety of healthy foods and avoid high foods in unhealthy fats, such as saturated fats and trans fats (read food labels can help help find out if your favorite snacks contain these malsayan ingredients.) try to eat at least five portions of fruits and vegetables every day. avoid soft drinks and fruit drinks. Don't smoke. can damage the heart and blood vessels. your heart deserves to be loved for all the work that does it. He started pumping blood before he was born and will continue to pump all your life. Life.
