Week 13 Terms

Aldosterone A hormone secreted by the adrenal cortex. Function in regulated in sodium and potassium
Anabolism The building up of the body substance, a process by which a cell takes from the blood and substances required for repair and growth
Ascites Accumulation of fluid in the abdominal cavity in amounts that are clinically detected
Catabolism The destructive phase of metabolism, the opposite of anabolism (usually there is a release in energy)
Dependent Edema Edema affecting most severely the lowermost parts of the body
Diffusion The movement of particles from a high to low area of concentration
ECF Extracellular fluid, or fluid outside the cells
Hyperkalemia Potassium level of 5 mEq/L in the blood stream
Hypernatremia A sodium level above 142 mEq/L in the blood stream
Hypertonic A solution more concentrated than that with which is compared
Hypokalemia Extreme potassium depletion in the circulating blood and weakness can occur
Hyponatremia Decreased concentration of sodium in the blood
Hypotonic A solution of lower osmotic pressure than another
ICF Intracellular fluid
Interstitial Pertaining to the spaces between the cells. A subcompartment of ECF
Intracellular Fluid inside the cells
Intravascular Within the blood vessels
Isotonic Having the same osmotic pressure as the solution it is being compared to
mEq Milliequivalent
Oncotic Pressure Is the osmotic pressure exerted by proteins
Osmolarity The number of dissolved particles within the unit of fluid determines the osmolarity of the solution
Osmotic Pressure Determined by the concentration of solutes, the amount of hydrostatic pressure needed to stop the flow of water by osmosis
Osmosis The movement of water from a low to high area of concentration
Periorbital Surrounding the socket of the eye
Plasma The liquid part of the blood
Selectively Permeable Membrane A membrane that allows selected substances, molecules and ions to diffuse through
Specific Gravity Weight of a substance compared with an equal volume of water
Tonicity In body fluid physiology, this refers to the effective osmotic pressure equivalency and related to the concentration of particles in the solution
Tubular Reabsorption The process whereby useful substance such as water, glucose and sodium chloride are returned to the blood
