ANATOMY

Detailed explanation-1: -Adipose tissue is one of the most hydrated of all tissues in the human body. The most abundant cation in intracellular fluid is sodium. Solutes, regardless of size, are able to move freely between compartments because water carries them along the osmotic gradients.

Detailed explanation-2: -The distribution of fluid throughout the body can be broken down into two general categories: intracellular fluid and extracellular fluid.

Detailed explanation-3: -Sodium, potassium, and chloride are the significant electrolytes along with magnesium, calcium, phosphate, and bicarbonates.

Detailed explanation-4: -Normal ranges are from 1.013–1.029; a USG of ≥1.030 suggests dehydration and 1.001–1.012 may indicate overhydration (2).
