Cardiovascular System and Circulatory System projectvideo of a labeled animated diagram of the Circulatory System labeled diagram of the heart and an animated diagram of the heart. components of the cardiovascular system and their functionsBloodThe blood delivers essential nutrients and oxygen and removes wastes and carbon dioxide to be processed or removed from the body.Arteries, veins and capillariesArteries carry blood away from the heart. The capillaries gradually join up with one another to form large vessels called veins. Veins carry blood towards the heart.HeartIt supplies oxygen and nutrients to our bodies by working with the respiratory system.Why exercise is good for the body? Exercising causes the body to produce endorphins, chemicals that can help a person to feel more peaceful and happy. Exercise can help some people sleep better. It can also help some people who have mild depression and low self-esteem.Increased cardiac output is due to an increase in both heart rate and stroke volume. When the level of exercise exceeds 40% to 60% of the individual's capacity, stroke volume has either plateaued or begun to increase at a much slower rate. The heart rate during exercise below is the diagramThe pressure of the blood in the circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.Bulletin factors that affect blood pressure-Smoking.-Being overweight or obese.-Lack of physical activity.-Too much salt in the diet.-Too much alcohol consumption (more than 1 to 2 drinks per day)-Stress.-Older age.-GeneticsDiseases of the cardiovascular systemDiseasesSymptomsprevention if possibleHeart attack is A blockage of blood flow to the heart muscle.Symptoms include tightness or pain in the chest, neck, back, or arms, as well as fatigue, lightheadedness, abnormal heartbeat, and anxiety. Women are more likely to have atypical symptoms than men.Eating foods low in saturated fat and cholesterol and high in fiber can help prevent high blood cholesterol. Eat a lot of fruits and vegetablesCoronary artery disease is a Damage or disease in the heart's major blood vesselsCoronary artery disease can range from no symptoms, to chest pain, to a heart attack.To prevent the disease stop smoking control, your blood pressure, exercise a lot and eat healthy foodsCongenital heart disease is an abnormality in your heart's structure that you're born with.The symptoms are excessive sweating, poor feeding, rapid heartbeat, chest pain and fatigueIt’s not easy to prevent but you can reduce the risk of having a baby with that disease by checking and getting prescriptions from the doctorHeart failure is a chronic condition in which the heart doesn't pump blood as well as it should.The symptoms are shortness of breath, fatigue, swollen legs, and rapid heartbeatThe best way to prevent heart failure is to have a heart-healthy lifestyle and control existing health problems like high blood pressure and diabetes.Heart muscle disease An acquired or hereditary disease of the heart muscle. The symptoms are breathing less, swollen legs and feet, and bloated bellyto prevent the disease the person have to stop drinking, stop smoking, doing exercise and having healthy body weightFacts about the cardiovascular system are many among them are the heart beats around billion times in the normal person’s life, about 8 million blood cells die in the human body every second and the same born in every second and there are 5 million red blood cells and also a normal adult carries about 5 liters of blood.4 types of congenital heart defects?Aortic Stenosis- Narrowing of the valve in the large blood vessel branching off the heart.Atrial septal defect- A birth defect that causes a hole in the wall between the heart's upper chambers (atria)Coarctation of the Aorta- A narrowing of the large blood vessel (aorta) that leads from the heart.Atrioventricular Canal Defect- The condition occurs when there's a hole between the heart's chambers and problems with the valves that regulate blood flow in the heart.How are the diseases diagnosed?Severe congenital heart defects generally are diagnosed during pregnancy or soon after birth. Less severe defects often aren't diagnosed until children are older. Minor defects often have no signs or symptoms.How are they treated?Doctors repair congenital heart defects with catheter procedures or surgery. Sometimes doctors combine catheter and surgical procedures to repair complex heart defects, which may involve several kinds of defects. The treatment your child receives depends on the type and severity of his or her heart defect.Possible long term effects? Children who have complex heart defects need long-term care from trained specialists. This will help them stay as healthy as possible and maintain a good ................
