what percent of body weight is extracellular fluid?
430668
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.

Extracellular fluid (ECF) or extracellular fluid volume (ECFV) usually denotes all body fluid outside of cells, and consists of plasma, interstitial, and transcellular fluid. An extracellular matrix is an extracellular fluid space containing cell-excreted molecules, and they vary in their type and function.

Water is of major importance to all living things; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human adult body is water.

Within the extracellular fluid, the major cation is sodium and the major anion is chloride. The major cation in the intracellular fluid is potassium. These electrolytes play an important role in maintaining homeostasis.

Excretory systems regulate the chemical composition of body fluids by removing metabolic wastes and retaining the proper amounts of water, salts, and nutrients. Components of this system in vertebrates include the kidneys, liver, lungs, and skin.

The blood plasma volume totals of 2.7–3.0 liters (2.8–3.2 quarts) in an average human. It is essentially an aqueous solution containing 92% water, 8% blood plasma proteins, and trace amounts of other materials.

The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets. Red blood cells (RBC) deliver oxygen from your lungs to your tissues and organs.

Plasma is a mixture of water and many other constituents, which carry blood cells and oxygen to various parts of the body. Interstitial fluid makes up the large part of the extracellular fluid in organisms.

Physical Characteristics It is an extracellular matrix in which blood cells are suspended in plasma. It normally has a pH of about 7.4 and is slightly denser and more viscous than water. Blood contains red blood cells (RBCs), white blood cells (WBCs), platelets, and other cell fragments, molecules, and debris.

Protein and minerals account for 15% and 5% of body composition, respectively. The 1018 cells forming the cellular body composition domain can be divided into connective tissue cells (fat cells, blood cells, and bone cells), epithelial cells, neural cells, and muscle cells.

percentage of water 50 to 70 percent of body weight, approximately 60 percent in healthy adults and an even higher percentage in children.

There's enough blood in the human body to fill a bit more than a 1-gallon milk jug. The average adult has about 1.2 to 1.5 gallons (4.5 to 5.5 liters) of blood circulating inside their body, said Dr. Daniel Landau, a hematologist and oncologist at the University of Florida Cancer Center – Orlando Health.

The ideal body water percentage varies. In general, women have a lower body water percentage than men. This is because women have more tissue than men. The ideal percentage for adult women will fluctuate between 45 and 60%, while the ideal percentage for adult men will be between 50 and 65% of the total body.

The human body contains many salts, of which sodium chloride (AKA common table salt) is the major one, making up around 0.4 per cent of the body's weight at a concentration pretty well equivalent to that in seawater.

Total body water can be subdivided into two major compartments, intracellular fluid which is fluid inside cells, and extracellular fluid which is fluid outside of cell like in the blood and in the interstitial tissue between cells.
