Adrenal gland Flashcards
1
Q
Adrenal gland secretes
A
Glucocorticoids- cortisol
Mineralcorticoids- aldosterone
2
Q
Cortisol
A
Body’s stress response
CRH acts on anterior pituitary to secrete ACTH
ACTH triggers adrenal cortex release
affects metabolism and sodium/water balance
3
Q
Aldosterone
A
Regulated by RAAS system
Helps maintain extracellular fluid volume through excretion of potassium and re absorption of water by kidneys
4
Q
RAAS system
A
- Kidneys sense change in blood volume,pressure, and sodium
2.Renin is secreted by kidney - Renin converts angiotensinogen to angiotensin 1
- Reaction causes aldosterone to be released
5.Aldosterone acts on kidneys to reabsorb Na and water
6.Leads to increased blood pressure and serum Na
