Question

Interstitial fluid is _____ fluid, _____% Ca, and has _____ proteins.

a) Extracellular; 0.1%; Albumin
b) Intracellular; 1%; Fibrinogen
c) Intracellular; 0.5%; Hemoglobin
d) Extracellular; 2%; Globulin

Answer 1

Interstitial fluid is extracellular and contains a small percentage of calcium, approximately 0.1%, and proteins such as albumin.

Step-by-step explanation:

Interstitial fluid is the fluid that surrounds the cells of multicellular animals and is a key component of the extracellular fluid (ECF). Since interstitial fluid is part of the ECF, not the intracellular fluid (ICF), we can deduce that it is not located within the cells but rather in the spaces between them. This fluid provides nutrients to cells and aids in waste removal. It contains small amounts of various ions including calcium (Ca), and the amount of proteins present in the interstitial fluid is lower compared to plasma.

Considering this information along with the details provided, the correct answer to the student's question is 'a) Extracellular; 0.1%; Albumin'. Interstitial fluid is extracellular, it has a small percentage of calcium (much less than 1%), hence approximating to 0.1%, and contains proteins such as albumin, though in lower concentrations than in plasma.
