Pathophysiology: Ch 4. Cellular Environment Flashcards
Acidosis
a condition in which blood pH is lower than 7.35
Active Transport
Movement of particles across the membranes requiring energy for the movement from an area of low concentration to an area of high concentration
Aldosterone
a hormone secreted by the adrenal gland that acts on the kidney to increase resorption of sodium into the blood and elimination of potassium in the urine
Alkalosis
a condition in which the blood pH is greater than 7.45
Angiotensin II
the chemical responsible for stimulation sodium resorption by the kidneys, decreasing blood flow to the kidneys and decreasing the glomerular filtration rate
ADH Antidiuretic Hormone
a hormone involved in the water balance of the body
Ascities
an abnormal accumulation of fluid in the peritoneal cavity
Barorecptors
Receptors found in the carotid sinus and aortic arch that senses changes in the pt’s blood pressure
Buffers
Molecules that modulate changes in pH to keep it in the physiologic range
Cellular Environment
The distribution of cells, molecules, and fluids throughout the body
Edema
accumulation of excess fluid in interstitial space
Extracellular Fluid
Fluid found outside of the cells but within the body
Hypercalcemia
an increased serum calcium level
Hyperkalemia
an elevated blood serum potassium level
Hypernatremia
a blood serum sodium level greater than 148 mEq/L and a serum osmolarity greater than 295 m0sm/kg
