Water and Energy Flashcards
(49 cards)
Intravascular fluid is located in the:
blood and lymph
Extracellular fluids include:
intravascular fluid and interstitial fluid
Major regulators of extracellular fluid:
kidneys
Electrolytes help to control:
the volume of water within the fluid compartments
movement of water is called:
osmosis
Extracellular fluid in osmosis:
Na+
Intracellular fluid in osmosis:
K+ (potassium)
diffusion of water through a selectively permeable membrane:
osmosis
do substances like glucose, amino acids and ions move freely across membranes?
NO
Water moves toward where solutes are more;
concentrated
intracellular water volume depends largely on:
intracellular concentration of potassium ions.
extracellular water volume depends primarily on:
the extracellular concentration of sodium ions.
Each minute you produce about how much urine?
1mL
Kidneys can control what in urine?
the volume of urine and the amount of ions in urine
Kidneys can control what in urine?
the volume of urine and the amount of ions in urine
volume of blood pumped into systemic circulation per minute:
Cardiac output
how much Cardiac output do kidneys receive?
about 21%
The filtrate produced in Bowman’s capsule contains:
salts, glucose, amino acids, vitamins, urea, and other small molecules
BMR of kidneys at rest:
10%
is the most energy demanding organ of your body:
the kidney
The pituitary gland releases:
antidiuretic hormone (ADH)
ADH stimulates the nephrons in the kidneys to:
produce less urine
Adrenal glands secrete:
aldosterone.
Aldosterone signals kidneys to reduce the
elimination of sodium in urine
