Disorders of Fluid
Disorders of Fluid, Electrolyte, and Acid-Base Balance
Term | Definition |
---|---|
intracellular fluid | 2/3 of the body's fluid |
extracellular fluid | 1/3 of the body fluid |
interstitial fluid | surrounds cell in tissue |
intravascular fluid | blood plasma |
transcellular fluids | fluids in defined spaces, like cerebral spinal fluid. |
osmosis | movement of water from low solutes to high solutes concentration. |
active transport | requires ATP moves molecules to large to diffuse. |
oncotic pressure | pull/attracts water by making plasma proteins force fluid back into capillaries |
capillary | responsible for interstitial fluid exchange |
aldosterone | Hormone secreted by the adrenal cortex. increases sodium absorption and potassium secretion. |
antidiuretic hormone | Decreases the release of solutes in the kidney (pee less) |
diffusion | Movement of particles from high concentration to low. |
edema | Swelling of a tissue |
facilitated diffusion | Diffusion using a transport molecule. |
hydrostatic pressure | The force in the capillaries that pushes fluid into the tissue. |
hypercalcemia | Excessive calcium in the blood. |
hyperkalemia | Excessive potassium in the blood. |
hypernatremia | Excessive sodium in the blood. |
hypocalcemia | Low calcium in the blood. |
hypokalemia | Low potassium in the blood |
hyponatremia | Low sodium in the blood |
natriuretic peptides | Hormones that stimulates elimination of solutes. ANP & BNP |
osmolarity | concentration of solutes in 1L of water. |
osmotic pressure | The force that uses proteins to pull fluid back into the capillaries from tissue. |
hypotonic | Low solutes in plasma. |
hypertonic | High solutes in plasma |
