1. Left ventricle [A] Valve of the heart consisting of two cusps attached by chordae tendineae, present between the left atrium and left ventricle 2. Right ventricle [B] Receiving chamber of the heart that moves deoxygenated blood from the vena cava 3. Left atrium [C] Outgrowths of cardiac muscle that help secure atrioventricular valves in place 4. Right atrium [D] Largest vessels of the body that move deoxygenated blood into the right atrium 5. Pulmonary trunk [E] Shared wall between the right and left atria 6. Vena Cava [F] Receiving chamber of the heart that moves oxygenated blood from the pulmonary veins 7. Aorta [G] Valve of the heart consisting of three cusps attached by chordae tendineae, present between the right atrium and right ventricle 8. Bicuspid/Mitral [H] Pumping chamber of the heart that moves oxygenated blood into the aorta 9. Tricuspid [I] Valve of the heart consisting of three cusps, present between the right ventricle and pulmonary trunk 10. Aortic semilunar [J] Vessel that moves deoxygenated blood from the right ventricle to the lungs. 11. Pulmonary Semilunar [K] Shared wall between the right and left ventricles 12. Pulmonary veins [L] Pumping chamber of the heart that moves deoxygenated blood into the pulmonary trunk 13. Interventricular septum [M] Valve of the heart consisting of three cusps, present between the left ventricle and aorta 14. Interatrial septum [N] Largest vessel of the body that moves rt by two large veins known as theand enters the, quickly passing by the openvalve, where blood then enters and fills thechamber.After filling, the cardiomyocytes contract, produce force on the blood and push openthevalve and allow blood to exit into theBlood now enters the circulation of the lung for gas exchange to occur. Onceoxygenated, blood returns to the heart from the lungs by way of four large vesselscalled the, blood then moves into theandpast the openvalve filling thechamber.From here, oxygenated blood is pushed past thevalve and intothewhere blood is pumped into the systemic circuit.
