Understanding Human Body Fluids: Composition, Function, and Blood Properties

1. What are the body fluid compartments, their measurements, and composition?

TBW%: M:70 F:40%, ECF: 15%, ICF: 45%, Major cations: Cl-, K+, Major anions: Na+, CO2

TBW%: M:40 F:30%, ECF: 25%, ICF: 35%, Major cations: H+, Ca2+, Major anions: Mg2+, SO4

TBW%: M:50 F:60%, ECF: 30%, ICF: 20%, Major cations: Ca2+, Mg2+, Major anions: HCO3-, PO4

Understanding the body fluid compartments, their measurements, and composition is essential in understanding the distribution of fluids in the human body. The correct answer provides the accurate percentages of total body water, extracellular fluid, and intracellular fluid, along with the major cations and anions present.

2. Blood: Specific Gravity

3) WBC: 1075

1) Plasma: 1060

2) RBC: 1020

Specific gravity of blood is related to its relative density compared to water, with variations based on factors like hematocrit, plasma proteins, and water content. Correct measurements involve comparing the density of blood with water using specific techniques like pyconometers or Hammar Schlags method.

3. What factor primarily determines the viscosity of blood?

Amount of plasma in blood

Blood pressure

Red blood cell count

Viscosity of blood is primarily determined by hematocrit, which is the percentage of red blood cells in the blood. Changes in hematocrit can significantly affect blood viscosity.

4. What does Hematocrit measure?

The level of platelets in the blood.

The oxygen carrying capacity of red blood cells.

The amount of white blood cells in whole blood.
