Detailed explanation-1: -The interstitial fluid is found in the interstitial spaces, also known as the tissue spaces. On average, a person has about 11 liters (2.4 imperial gallons or about 2.9 U.S. gal) of interstitial fluid that provide the cells of the body with nutrients and a means of waste removal.

Detailed explanation-2: -This compartment can be further subdivided into the interstitial fluid ( 25% of total body fluid volume), plasma ( 7% of total body fluid volume), and transcellular fluid ( 1% of total body fluid volume). Interstitial fluid is the fluid that directly bathes the cells and tissues in the body.

Detailed explanation-3: -The body’s fluid separates into two main compartments: Intracellular fluid volume (ICFV) and extracellular fluid volume (ECFV). Of the 42L of water found in the body, two-thirds of it is within the intracellular fluid (ICF) space, which equates to 28L.

Detailed explanation-4: -There are three major fluid compartments; intravascular, interstitial, and intracellular. Fluid movement from the intravascular to interstitial and intracellular compartments occurs in the capillaries.

Detailed explanation-5: -The adult human body is made up of 60% water and is divided into extracellular and intracellular fluid compartments. Extracellular fluid is present outside the cells and makes up ⅓ of the total body water. Intracellular fluid is present inside the cells and makes up ⅔ of the total body water.
