Question

Which two fluid compartments make up the extracellular fluid?

1. Cytosol and plasma
2. Plasma and interstitial fluid
3. Intracellular fluid and plasma
4. Interstitial fluid and intracellular fluid

Answer 1

The extracellular fluid is comprised of plasma and interstitial fluid, which are essential for nutrient transport and physiological balance.

Step-by-step explanation:

The two fluid compartments that make up the extracellular fluid (ECF) are plasma and interstitial fluid. Plasma is the fluid component of the blood, whereas interstitial fluid surrounds all cells that are not blood cells. Both of these fluids are critical in transporting nutrients, gases, and wastes between the blood vessels and the cells, and they play a significant role in maintaining the physiological balance within the body.
