Question

Bicarbonate ions are often found in which fluid compartment?

1) Intracellular fluid (ICF)
2) Extracellular fluid (ECF)
3) Interstitial fluid
4) Plasma

Answer 1

Bicarbonate ions are often found in the extracellular fluid (ECF) compartment, specifically in the interstitial fluid and plasma.

Step-by-step explanation:

Bicarbonate ions are often found in the extracellular fluid (ECF) compartment, specifically in the interstitial fluid and plasma. The extracellular fluid surrounds all cells in the body and consists of the fluid component of the blood (plasma) and the interstitial fluid between the cells. Bicarbonate ions are important in maintaining pH balance and play a role in buffering acids and bases in the body.
