Module 2 Blueprint Flashcards
1
Q
The adrenal gland is made up of what two structures
A
adrenal cortex and adrenal medulla
2
Q
The adrenal cortex secretes
A
corticosteroids (cortisol) and alderosterone (mineralocorticoid)
3
Q
How does aldosterone work?
A
promotes sodium and water reabsorption and potassium excretion
4
Q
Aldosterone is regulated by the?
A
RAAS system and adrenocorticotropic hormone (ACTH)
5
Q
How does the RAAS system work
A
renin is produced in kidneys from sodium or blood loss. renin coverts angiotensinogen into angiotensin 1, then angiotensin 2. Angiotensin II triggers the release of aldosterone. Aldosterone promotes reabsorption in the kidneys to raise plasma level
6
Q
How does serum potassium level control aldosterone secretion
A
aldosterone is released when serum potassium is above normal. Aldosterone then enhances kidney excretion of potassium, correcting fluid and electrolyte imbalances
7
Q
What does cortisol affect
A
stress responses, metabolism, helps catecholamine function, maintenance of heart cell excitability
8
Q
Describe the release of cortisol (negative feedback loop)
A
low blood cortisol levels –> secretion of CRH by hypothalamus –> causes pituitary to release ACTH –> ACTH releases cortisol from adrenal cortex
