Water and Electrolytes 4 Flashcards
What is the primary and secondary electrolyte in the ICF
Primary: K+ Potassium
Second: Mg2+ magnesium
Sodium and Potassium can pass through a cell membrane with the help of what
Na+ K+ ATPase pump
What is the ratio of the movement of sodium and potassium ions across the membrane
3 Na+ Sodium out
2 K+ Potassium in
What is the electrical charge/ potential of the Sodium Potassium ATPase pump
-70 mV
Increased osmolality (osmotic pull) in the blood vessels, what does this most likely mean?
Dehydration= Increased ADH from Pituitary
The _________ is the first water regulator
Pituitary gland
What is the drug name for ADH and its effects
vasopressin (retain water, decreased urine output)
What does Aldosterone do specifically?
Increased sodium retention
Glomeruli can sense less blood through the afferent and efferent arterioles in the pelvis, and releases what
RENIN - Angiotensin - Aldosterone System
(from adrenal glands)
Three effects of the Renin - Angiotensin - Aldosterone System
1.Na+ Sodium retention
2. Water conservation
3. Increased thirst
