acidosis
an acid-base imbalance characterized by an increase in H+ concentration (decreased blood pH) (A low arterial pH due to reduced bicarbonate concentration is called metabolic ___; a low arterial pH due to increased PCO2 is called respiratory ___.)
ascites
a type of edema in which fluid accumulates in the peritoneal cavity
active transport
physiologic pump that moves fluid from an area of lower concentration to one of higher concentration; this actions requires adenosine triphosphate for energy
alkalosis
an acid-base imbalance characterized by a reduction in H+ concentration (increased blood pH) (A high arterial pH with increased bicarbonate concentration is called metabolic___; a high arterial pH due to reduced PCO2 is called respiratory ___.)
diffusion
the process by which solutes move from an area of higher concentration to one of lower concentration; does not require expenditure of energy
homeostasis
maintenance of a constant internal equilibrium in a biologic system that involves positive and negative feedback mechanisms
hydrostatic pressure
the pressure created by the weight of fluid against the wall that contains it. In the body, hydrostatic pressure in blood vessels results from the weight of fluid itself and the force resulting from cardiac contraction.
hypertonic solution
a solution with an osmolality higher than that of serum
hypotonic solution
a solution with an osmolality lower than that of serum
isotonic solution
a solution with the same osmolality as serum and other body fluids
osmolality
the number of milliosmoles (the standard unit of osmotic pressure) per kilogram of solvent; expressed as milliosmoles per kilogram (mOsm/kg).
osmolarity
the number of milliosmoles (the standard unit of osmotic pressure) per liter of solution; expressed as milliosmoles per liter (mOsm/L); describes the concentration of solutes or dissolved particles
osmosis
the process by which fluid moves across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration; the process continues until the solute concentrations are equal on both sides of the membrane
tonicity
fluid tension or the effect that osmotic pressure of a solution with impermeable solutes exerts on cell size because of water movement across the cell membrane
intravascular space
(the fluid within the blood vessels) contains plasma, the effective circulating volume. Approximately 3 L of the average 6 L of blood volume in adults is made up of plasma. The remaining 3 L is made up of erythrocytes, leukocytes, and thrombocytes.
