Study Notes
Blood Flow Through the Heart and Lungs
- Deoxygenated blood and carbon dioxide are collected by the superior and inferior vena cava.
- Blood enters the right atrium from the vena cava.
- The tricuspid valve facilitates blood flow from the right atrium to the right ventricle.
- The right ventricle pumps blood through the pulmonic valve into the pulmonary arteries, directing it toward the lungs (left or right).
Gas Exchange in the Lungs
- In the lungs, blood travels through arterioles and into capillaries.
- Capillaries allow for the exchange of gases: oxygen is absorbed and carbon dioxide is released.
- Venules collect oxygenated blood from the capillaries.
- Pulmonary veins (four total) transport oxygenated blood back to the heart.
Return to the Heart
- Oxygen-rich blood enters the left atrium via the pulmonary veins.
- The bicuspid (mitral) valve enables blood flow from the left atrium to the left ventricle.
- The left ventricle contracts and sends blood through the aortic valve into the aorta.
- From the aorta, blood is distributed throughout the systemic system to supply oxygen and nutrients to the body.
