Question

question 2 (4 points) explain how blood flows through the heart, to the lungs, and through the body. be specific (i.e. trace the flow from chamber to chamber and through the major vessels and back to the heart).

Explanation:

Deoxygenated blood enters the right atrium via the superior and inferior vena cava. It then passes through the tricuspid valve into the right ventricle. From the right ventricle, it is pumped through the pulmonary valve into the pulmonary artery and travels to the lungs for oxygenation. Oxygen - rich blood returns to the heart via the pulmonary veins into the left atrium. It passes through the mitral valve into the left ventricle. The left ventricle pumps the oxygen - rich blood through the aortic valve into the aorta, which distributes it throughout the body. Deoxygenated blood then returns to the heart via the vena cava, completing the cycle.

Answer:

Deoxygenated blood enters right atrium via vena cava, passes to right ventricle, then to lungs via pulmonary artery. Oxygen - rich blood returns to left atrium via pulmonary veins, goes to left ventricle, and is pumped to body via aorta. Deoxygenated blood returns to heart via vena cava.
