|
|
Term
|
Definition
the movement of molecules from an area of high concentration to one of low concentration
occurs in liquids, gases and solids |
|
|
Term
|
Definition
the movement of water b/t two compartments separated by a membrance permeable to water but not to a solute.
Water moves through the membrane from an area of low solute concentration to an area of high solute concentration, moves from the more dilute compartment (has more water) to the side that is more concentrated (has less water) |
|
|
Term
|
Definition
| a process in which molecules move against the concentration gradient. External energy is required. |
|
|
Term
|
Definition
the force within a fluid compartment.
blood pressure generated by the contration of the heart |
|
|
Term
|
Definition
| the osmotic pressure of a colloid in solution, such as when there is a higher concentration of protein in the plasma on one side of a cell membrane than in the neighboring interstitial fluid. |
|
|
Term
|
Definition
| a term sometimess used to describe the distribution of body water. |
|
|
Term
|
Definition
| the normal distribution of fluid in the ICF and ECF compartments |
|
|
Term
|
Definition
| an abnormal accumulation of intersitial fluid |
|
|
Term
|
Definition
| when fluid accumulates in a portion of the body from which it is not easily exchages with the rest of the ECF. |
|
|
Term
|
Definition
| abnormal accumulation of blood in the interstitial tissue, commonly known as swelling |
|
|
Term
|
Definition
| characterized by a condition in which a finger pressed into the skin over an accumulation of fluid will result in a temporary depression in the skin; normal skin and subsutaneous tissues quickly rebound when the pressure is released |
|
|
Term
|
Definition
| the expected resiliency of the skin caused by the outward pressure of the cells and interstitial fluid |
|
|
Term
|
Definition
| the osmotic pressure of a solution expressed in osmoles or milliosmoles per liter of the solution |
|
|
Term
|
Definition
| a solution having a lower concentration of solute than another solution, hence exerting less osmotic pressure that that solution |
|
|
Term
|
Definition
| pertaining to a solution that causes no change in cell volume |
|
|
Term
|
Definition
| a solution that increases the degree of osmotic pressure on a semipermeable membrane |
|
|
Term
|
Definition
| the amount of fluid lost on a daily basis from the lungs, skin, respiratory tract, and water excreted in the feces; the exacted amount cannot be measured, but it is estimated to be between 40 and 600 mL in the adult under normal circumstances |
|
|
Term
|
Definition
| a sensation accompanying the urge but not always leading to vomiting |
|
|
Term
|
Definition
| the frocible voluntary or involuntary emptying of the stomach contents through the mouth |
|
|
Term
|
Definition
increased formation and secretion of urine.
Occurs in conditions such as diabetes mellitus, diabetes insipidus, and acute renal failure |
|
|
Term
| Intracellular Fluid Compartment |
|
Definition
provides cells witht the internal aqueous medium necessary for their chemical functions.
Anything that affects fluid loss at the cellular level has significant implications for the entire body. |
|
|
Term
| Extracellular Fluid Compartment |
|
Definition
found outside body cells and serve as the body's transportation system.
Carries water, electrolytes, nutrients, and oxygen to cells and remove waste products of cellular metabolism. |
|
|
Term
|
Definition
| the space within the arteries, veins, and capillaries, whose major function is to carry blood |
|
|
Term
|
Definition
between the cells and vascular compartments, in spaces known as the interstitial spaces,
Transports nutrients and waste products between the cells and blood vessels.
To much or too little fluid in this space affects bodily functions. |
|
|
Term
|
Definition
| found in spaes in the cerebrospinal canals in the brain, and in the lymph tissues, synovial joints, and eyes |
|
|
Term
|
Definition
| the sum of the forces tending to move water and dissolved substances out of the blood vessels and the opposing forces. |
|
|
Term
|
Definition
| pressure exerted by the weight of fluid within a compartment or closed system. |
|
|
Term
| Tissue hydrostatic pressure |
|
Definition
| pushes fluid into the capillary |
|
|
Term
