1) super vena cava 2) inferior vena cava 3) right atrium 4) left atrium 5) pulmonary trunk 6) left pulmonary veins 7) right ventricle

1. What type of heart valve is between the atria and the ventricles? Atrioventricular valves 2. What type of heart valve is between the right ventricle and the pulmonary trunk, as well as the left ventricle and the aorta? 1-pulmonary semilunar valve 2-aortic semilunar valve 3. What is the conduction system of the heart? Consists of cardiac muscle cells and conduction fibers that initiate impulses and also conduct them throughout the heart. Main components are the SA and AV nodes. 4. What type of cells initiate and conduct the electrical activity of the heart? Conducting cells carry the hearts electrical signal, and the muscle cells enable the heart’s chambers to contract. 5. Define SA node and AV node. AV-sends impulses to the ventricles which causes them to contract or pump. SA-then sends another signal to the atria for it to contract and start the cycle over....
