The human body and even its individual body fluids may be conceptually divided into various fluid compartments, which, although not literally anatomic compartments, do represent a real division in terms of how portions of the body's water, solutes, and suspended elements are segregated. The two main fluid compartments are the intracellular and ...
Extracellular fluid makes up about one-third of body fluid, the remaining two-thirds is intracellular fluid within cells. [3] The main component of the extracellular fluid is the interstitial fluid that surrounds cells.
The extracellular fluid compartment is further subdivided into the interstitial fluid and the intravascular fluid compartments. Body fluids, bodily fluids, or biofluids, sometimes body liquids, are liquids within the body of an organism. [1] In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is ...
In a 72 kg (159 lb) body containing 40 litres of fluid, about 25 litres is intracellular, [9] which amounts to 62.5%. Jackson's texts states 70% of body fluid is intracellular. [10] 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, [9] which amounts to 37.5%.
[1] [2] The fluid in this space is called interstitial fluid, comprises water and solutes, and drains into the lymph system. [2] The interstitial compartment is composed of connective and supporting tissues within the body – called the extracellular matrix – that are situated outside the blood and lymphatic vessels and the parenchyma of organs.
In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal ...
Euvolemia is the state of normal body fluid volume, including blood volume, interstitial fluid volume, and intracellular fluid volume; hypovolemia and hypervolemia are imbalances. Water is necessary for all life on Earth. Humans can survive for 4 to 6 weeks without food but only for a few days without water.
The total body water can be divided into two compartments called extracellular fluid (ECF) and intracellular fluid (ICF). The majority of the sodium in the body stays in the extracellular fluid compartment. [27] This compartment consists of the fluid surrounding the cells and the fluid inside the blood vessels.
