CH 20 Vessels part 4 (Lab exam 3) Flashcards
4 hormones that regulate blood pressure?***
- Renin
- Aldosterone
- ADH
- ANP
What steps does aldosterone take to increase BP?
- Aldosterone released from the adrenal cortex will go to the kidneys.
- Kidney’s will start reabsorption and move sodium into the blood.
- BV will increase and so will BP.
Blood volume is directly linked to?
Blood pressure
When is aldosterone released?
When angiotensin 2 is released
Kidneys can’t function on? ***
Low blood pressure
