Final answer:
The statement that blood flows to the lower body from the heart through the descending aorta is true; the descending aorta carries oxygenated blood to the lower extremities.
Step-by-step explanation:
Blood does indeed flow to the lower body from the heart through the descending aorta. This statement is true. The heart acts as a powerful pump that circulates blood throughout the body via the circulatory system. After blood is oxygenated in the lungs, it returns to the heart and is then pumped out through the left ventricle into the aorta. The aorta is the main artery that carries oxygenated blood away from the heart to the rest of the body. The descending aorta is the portion of the aorta that travels down through the abdomen to distribute blood to the abdomen and lower extremities. The blood is then returned to the heart through the veins, with the deoxygenated blood from the lower body entering through the inferior vena cava.
The descending aorta carries oxygenated blood from the heart to the lower body. Oxygenated blood is pumped by the left ventricle into the ascending aorta, which then branches into the descending aorta. The descending aorta supplies oxygenated blood to the organs and tissues of the lower body, including the abdomen and lower extremities.
