1
Q
What produces angiotensinogen
A
Liver
2
Q
Macula Dena’s detects what
Macula Densa secretes what (in response to what)
What does this cause
A
Bp /nacl
Prostaglandins (when low bp or low nacl in blood)
Causes granular cells —> renin
3
Q
What secretes renin
In response to what
A
Granular cells (kidney)
Prostaglandins from macula densa
4
Q
Renin affect
A
Angiotensin 1 to 2
5
Q
What produces ace and where are they
A
Vascular Endothelial cells of lung
6
Q
Effect of aldoesterone generally
A
Na reavsorbed
Blood vol rise
Bp rise
7
Q
Effect of renin generally
A
Na reabsorbed
Blood vol rise
Blood pressure rise
8
Q
Angiotenain2 effect
-
-
A
- adrenal Cortez —> aldosterone (Zona glomerulosa!!!!!)
- vasoconstriction (esp in efferent arteriolar of kidney glomerulus )
9
Q
stimulates adh production
A
- low blood volume
- high osmolality - osmoreceptors in hypothalamus
- lack of negative feedback from adh in blooood
so hypothal produces and post pit secretes
