Question:

Increased salt content of the blood will lead to

a) increased blood volume

b) decreased blood volume

c) no change in the blood volume.

Osmosis:

Osmosis is the movement of water through a semipermeable membrane from low to high solute concentration. Osmosis is very similar to diffusion except that it?s specific to water.

Answer and Explanation:

The correct answer is a) increased blood volume

Increased salt content is referring to an increased Na+ concentration in the blood. When you have a higher concentration of Na+ in the blood, because of osmosis, water will follow the Na+ into the blood. This increased water in the blood stream will lead to a higher blood volume and therefore a higher blood pressure.

Aldosterone is a drug that uses this process to increase blood pressure.
