Fluid compartments
Fluid Compartments
Fluid compartments (pronunciation: /ˈfluːɪd kəmˈpɑːtmənts/) are the various spaces within the human body where bodily fluids are stored or circulate.
Etymology
The term "fluid compartments" is derived from the Latin words "fluidus" meaning flowing, and "compartimentum" meaning a division or section.
Definition
Fluid compartments are divided into two main categories: the intracellular fluid (ICF) compartment and the extracellular fluid (ECF) compartment. The ICF compartment is the system that includes all fluid enclosed in cells by their plasma membranes, while the ECF compartment is the system that includes all body fluid outside of cells.
Related Terms
- Intracellular fluid: The fluid contained within cells.
- Extracellular fluid: The body fluid outside the cells.
- Interstitial fluid: A part of the extracellular fluid, which fills the spaces between cells and tissues.
- Plasma: The liquid component of blood, in which the blood cells are suspended.
- Lymph: The fluid that circulates throughout the lymphatic system.
Function
The fluid compartments play a crucial role in maintaining homeostasis in the body. They allow for the transport of gases, nutrients, and wastes between different parts of the body. The balance of fluids in these compartments is regulated by various mechanisms, including osmosis, diffusion, and active transport.
Disorders
Disorders related to fluid compartments include dehydration, edema, and various electrolyte imbalances such as hyponatremia and hyperkalemia. These conditions can result from a variety of causes, including illness, injury, or improper fluid intake or loss.
