Study Notes
Blood Flow Through the Heart
- Blood begins as deoxygenated, entering the right atrium from the superior and inferior vena cava.
- Flow proceeds through the tricuspid valve into the right ventricle.
- The right ventricle pumps blood through the pulmonary semi-lunar valve.
- The pulmonary artery transports deoxygenated blood to the lungs for oxygenation.
- In the lungs, carbon dioxide is exchanged for oxygen.
- Oxygenated blood returns to the heart via the pulmonary veins.
- The blood enters the left atrium before moving through the bicuspid (mitral) valve.
- Blood then flows into the left ventricle, where it is prepared for systemic circulation.
- The left ventricle ejects blood through the aortic semi-lunar valve.
- Finally, oxygenated blood is distributed to the body through the aorta.
