Which of the following parts of the circulatory system carries oxygenated blood?
A. An artery moving blood from the heart to the lungs
B. A vein moving blood to the heart from the body
C. An artery moving blood from the heart to a muscle cell
D. A venule moving blood to the heart from the liver
I think c!
Agree
To determine which part of the circulatory system carries oxygenated blood, we need to understand how blood is circulated in the body. The circulatory system consists of arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood toward the heart.
Let's consider the options given:
A. An artery moving blood from the heart to the lungs
This option suggests that an artery carries blood from the heart to the lungs. Typically, oxygen-depleted blood from the body flows into the heart, specifically the right atrium, and then is pumped to the lungs via the pulmonary artery. In the lungs, the blood is oxygenated and returned to the heart. Since the question asks for oxygenated blood, this option does not fit.
B. A vein moving blood to the heart from the body
This option suggests that a vein carries blood to the heart from the body. Generally, veins carry deoxygenated blood back to the heart. This option doesn't involve oxygenated blood, so it can be eliminated.
C. An artery moving blood from the heart to a muscle cell
This option suggests that an artery carries blood from the heart to a muscle cell. Arteries are responsible for carrying oxygenated blood away from the heart, supplying oxygen and nutrients to various parts of the body, including muscle cells. This suggests the possibility of oxygenated blood being carried. We need to consider the other options to have a clear answer.
D. A venule moving blood to the heart from the liver
This option suggests that a venule carries blood to the heart from the liver. Veins generally carry deoxygenated blood back to the heart. Therefore, this option does not involve oxygenated blood.
Based on the above analysis, C. An artery moving blood from the heart to a muscle cell sounds like the correct answer. However, we should double-check the answer by understanding the basic functions of arteries and veins.
