Nutrients move out of the blood and into the body cells through which blood vessels?
A. arteries
B. veins
C. capillaries
D. lymphatic vessels
To determine which blood vessels allow nutrients to move out of the blood and into the body cells, we need to understand the anatomy of the circulatory system.
The circulatory system consists of three types of blood vessels: arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart to the body tissues, while veins carry deoxygenated blood back to the heart. Capillaries are tiny, thin-walled vessels that connect arteries and veins, forming a network throughout the body.
When it comes to the movement of nutrients between the blood and body cells, the primary role is played by capillaries. Capillaries have a unique structure, with thin walls that allow for the exchange of substances between the blood and the surrounding cells. This exchange includes both the delivery of nutrients from the blood to the cells and the removal of waste products from the cells back into the blood.
Therefore, the correct answer is C. capillaries. Capillaries enable the transfer of nutrients from the blood and into the body cells, ensuring that cells receive the necessary nourishment to carry out their functions.
