The Structure & Function To describe the structure of the cardiovascular system To explain function and link this to physical features of the cardiovascular system. To follow instructions and physically “walk through” the cardiovascular system. To work in pairs and discuss. To recall the component parts of the blood and state their function. In pairs, use the following labels to annotate the diagram of the heart on your sheet. Left Atrium; Right Atrium; Left Ventricle; Right Ventricle; Pulmonary Vein; Pulmonary Artery; Vena Cava; Aorta. State the action that occurs in each of the above sections e.g blood flows through here at high pressure on its way around the body. Max time: 10min. What is meant by the term “Double Circulation”? In which chamber of the heart is the Sino Atrial Node (SAN) located? What is significant about the SAN? Both sides of the heart pump in synchronism. What does this mean? Each side of the heart pumps blood to a different region of the body. How are the heart and the adjoining vessels adapted to ensure: No back flow? Safe blood pressure readings (vessels do not rupture under pressure)? What happens to the pulse rate when: Activity decreases i.e. resting? Activity increases i.e. exercising? In pairs, match the beginnings and endings of the sentences in the card-sorting game. Discuss Check Max findings with neighbours. results with board. time: 10mins The blood is composed of four constituent parts: Red blood cells White blood cells Platelets Plasma Using the internet, research all, and state the function of each. Create a model of the constituents using household items.
