A ECL 365 SIWorksheet 10: Circulatory SystemWhat are the two components of the circulatory system found in vertebrates?The ____________ is the main pumping organ and is made up of cardiac muscle and surrounded by pericardium. The heart contains two types of chambers: the _____________, which have thin walls and receives blood, and the _____________, which have thicker walls and pump blood out to the body.In the diagram below, label the following types of blood vessels: arteries, arterioles, capillaries, veins, and venules.714375-3175__________________________________________________0__________________________________________________What is a structural difference between the arteries and veins? Why is this the case?_____________ are the sites of gas and material exchange between the tissues and circulatory system. They are very narrow and have thin, cellular layers. There are four components of blood: plasma, erythrocytes, leucocytes, and thrombocytes. Below, match each component to the correct definition/function.Blood ComponentDefinition/FunctionErythrocytes Red blood cells. Contain hemoglobin, the molecules used to transport oxygen.Leucocytes The largest component. Mostly water, but also contains nutrients, hormones, proteins, waste, and antibodies.Plasma Cells that function in blood clotting. Mammals have platelets that serve this functionThrombocytes White blood cells. Function in the immune system, neutralizing or removing foreign bodies. Many invertebrates have an ___________ system, meaning their blood empties out into the body cavity. All vertebrates have a ___________ system. What are some examples of other body systems that interact with the circulatory system?In the lymphatic system, the lymphatic vessels pick up excess liquid from the ____________. This liquid is then filtered by the ____________ ____________ before being returned to the blood stream.Many lineages have two different circuits in their cardiovascular system: the pulmonary and systemic circuits. Where do these two circuits take the blood?What does the gene Tbx5 do? Fill in the table with the characteristics of the circulatory system for each group.Vertebrate GroupCharacteristics of the Circulatory SystemFishAmphibiansReptilesBirdsMammals ................
