ANATOMY

Detailed explanation-1: -The intracellular fluid (ICF) and extracellular fluid (ECF) are separated by a semi-permeable cell membrane that is permeable to water but not to most solutes including electrolytes and proteins, which generally need transport systems to move across the membrane.

Detailed explanation-2: -The cell membrane surrounds the cytoplasm of living cells, physically separating the intracellular components from the extracellular environment.

Detailed explanation-3: -The membrane separates the extracellular space, outside of the cell, from the cytosol inside the cell. The plasma membrane is the border between the interior and exterior of a cell. As such, it controls passage of various molecules-including sugars, amino acids, ions, and water-into and out of the cell.

Detailed explanation-4: -The water content present on the inside of the cells is called the intracellular fluid (or ICF), and the water content present on the outside of the cells forms the extracellular fluid (or ECF). The cell membrane (semi-permeable membrane) separates the intracellular fluid from the extracellular fluid.

Detailed explanation-5: -The ICF has higher amounts of potassium, phosphate, magnesium, and protein compared to the ECF. The plasma has high concentrations of sodium, chloride, and bicarbonate, but lower levels of protein as compared to the ICF.
