Document Summary
Our internal environment is bathed in fluids. Because of homeostasis, the volume of fluid and concentration of ions is closely controlled so our organ systems can function properly. Body is divided into 2 major fluid compartments. Intracellular fluid compartment (icf inside all the cells: extracellular fluid compartment (ecf everything outside the cells) body) can be further divided into: The extracellular fluid (which makes up the internal environment of the. The interstitial fluid compartment (fluid directly outside, bathing the cells) The plasma (watery portion of the blood) Section 2. 4 a quick look at plasma. Plasma: pale yellow fluid that consists of about 92% water and. 8% other substances, such as proteins, ions, nutrients, gases, and waste products. It is a colloidal solution: a liquid containing suspended substances that do not settle out of solution. Most of the suspended substances are plasma proteins, which include albumins, globulins and fibrinogen.
