Question

what are the three major subdivisions of the extracellular fluid in the body? options: blood, water, and saliva; spinal fluid, cytosol, and blood; blood, urine, and saliva; plasma, interstitial fluid, and lymph; i dont know yet

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Blood is part of extracellular fluid, but water is a general component and saliva is a secretion, not a main subdivision of extracellular fluid. Eliminate.
• Option 2: Cytosol is intracellular fluid (inside cells), not extracellular. Spinal fluid is a type but not a major subdivision with cytosol and blood. Eliminate.
• Option 3: Urine and saliva are excretions/secretions, not main extracellular fluid subdivisions. Eliminate.
• Option 4: Plasma (liquid part of blood), interstitial fluid (between cells), and lymph (in lymphatic system) are the three major subdivisions of extracellular fluid. This matches the biological knowledge.

Answer:

D. Plasma, interstitial fluid, and lymph
