ANATOMY

Detailed explanation-1: -The extracellular fluid comprises approximately 20% of total body weight and further subcategorizes as plasma at approximately 5% of body weight and interstitial space which is approximately 12% of body weight.

Detailed explanation-2: -Extracellular Fluid Approximately 20 percent of the ECF is found in plasma. Plasma travels through the body in blood vessels and transports a range of materials, including blood cells, proteins (including clotting factors and antibodies), electrolytes, nutrients, gases, and wastes.

Detailed explanation-3: -Approximately, 35% (or 1/3) of total body water is in the extracellular fluid compartment, .

Detailed explanation-4: -Extracellular fluid (1/3 of body water) is fluid contained in areas outside of cells. For a 40-litre body, about 15 litres is extracellular, which amounts to 37.5%.

Detailed explanation-5: -Water accounts for approximately 60% of body weight in men and 55% in women, the difference reflecting the typi-cally greater body fat content in women. Approximately 66% of this water is in the intracellular fluid (ICF) and 33% is in the extracellular fluid (ECF); only 8% of body water is in the plasma (Fig.
