Question

What proportion of body fluid is found in these compartments?

1) Extracellular fluid
2) Intracellular fluid
3) interstitial fluid
4) plasma
5) lymph

Answer 1

Extracellular fluid, intracellular fluid, and interstitial fluid are the major compartments of body fluid.

Extracellular fluid includes blood plasma, interstitial fluid, and lymph, while intracellular fluid exists within cells. Interstitial fluid surrounds cells that are not blood cells. Plasma is the fluid component of blood, and lymph is a small volume of extracellular fluid.

Step-by-step explanation:

The proportion of body fluid found in different compartments is as follows:

Extracellular fluid: This includes blood plasma, interstitial fluid, and lymph. Plasma contains 7% protein, while hepatic lymph and subcutaneous fluid contain slightly less protein. The main components of extracellular fluid are NaCl, NaHCO3, and small amounts of Ca, Mg, K, H, phosphate, sulphate, organic acids, and non-electrolytes such as glucose, urea, and lipids. The pH value ranges from 7.35 to 7.45.Intracellular fluid: This exists within cells and constitutes about 50% of the total body weight.Interstitial fluid: This surrounds cells that are not blood cells. It represents about 15% of the total body weight.Plasma: This is the fluid component of the blood and accounts for about 5% of the total body weight.

Lymph: This is a component of the extracellular fluid and represents a relatively small volume in the body.
