How is water in the body distributed between the extracellular and intracellular fluid compartments?

In the body, water moves through semi-permeable membranes of cells and from one compartment of the body to another by a process called osmosis. Osmosis is basically the diffusion of water from regions of higher concentration to regions of lower concentration, along an osmotic gradient across a semi-permeable membrane.

How much intracellular fluid is in the human body?

Intracellular Fluid The ICF lies within cells and is the principal component of the cytosol/cytoplasm. The ICF makes up about 60 percent of the total water in the human body, and in an average-size adult male, the ICF accounts for about 25 liters (seven gallons) of fluid.

How many liters of total body water does an 80kg man have?

In an 80-kg man, the ECF volume averages 20 liters; thus, 1.2% of 20,000 ml equals 240 ml. A satiated ECF osmolality of 285 mosmol/kg would require ingestion and assimilation of 0.285 x 240 ml = 68.4 mosmol to induce drinking. This is equivalent to (6.245 g of NaCl/liter x 68.4 mosmol)/285 mosmol/kg = 1.5 g of NaCl.

What is the process of water moving through a semipermeable membrane?

The movement of water in and out of cells through a semipermeable membrane ( osmosis) is a passive process that doesn’t require energy and is controlled by the number of dissolved solids , or solute, in the fluids.

What is the difference between ICF and ECF?

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. While water moves passively via osmosis, sodium and potassium ions move in and out of cells using active transport ion pumps. The pumps are powered by adenosine triphosphate (ATP) to provide the energy to move the ions against their concentration gradients (i.e. sodium moves out of the cell and potassium is pumped in) and maintain the gradients inside and outside the cell.

What are the components of ECF?

The two main components of ECF are plasma and interstitial fluid (IF). The balance consists of cerebrospinal fluid, lymph, the synovial fluid in the joints, pleural fluid in the pleural cavities (lungs), pericardial fluid around the heart, peritoneal fluid in the peritoneal cavity ( abdomen ), and the aqueous humor of the eye. ...

What is extracellular water?
