Biology 3.1.2 Cardiac cycle
Karten in diesem Stapel (9)
- 1Why does blood from the right ventricle have low pressure?So that the capillaries aren't damaged by high pressures
- 2What are the three stages of the cardiac cycle in order?Atrial systole
Ventricular systole
Diastole - 3What happens during atrial systole?The walls of the atria contract, forcing blood into the ventricles
- 4What valve connects the arteries and ventricles?Atrioventricular valve
- 5What are the valves called in the aorta and pulmonary artery?Semi-lunar valves
- 6What happens during ventricular systole?The ventricles contract
- 7What do the elastic tissues in the walls of the ventricles do?Recoil to stretch out to return ventricles to its original size
- 8What causes the "lub-dub" sound of the heart beat?The shutting of valves (atrioventricular=lub semilunar=dub)
(sounds are in-order of which valve shuts first) - 9What keeps the valves from turning inside out?Tendons
