Flowchart
cardiac cycle
Flowchart content
deoxy blood goes to vena cava
goes to right atrium, atrio-ventricular valves open
goes into right ventricle, semi-lunar valves open
blood goes out pulmonary artery to lungs
oxy blood goes in pulmonary veins
goes to left atrium, atrio-ventricular valves open
goes into left ventricle, semi-lunar valves open
ventricles contract from apex upwards
goes out aorta and into the body
atrial systole - atria contract n push blood into ventricles
ventricle systole - ventricles contract, increasing pressure in V to push blood out
Atrial systole
ventricle systole
cardiac diastole - elastic recoils as heart relaxes causes low pressure in heart, refills chambers w blood from veins
