Bio/Biochem 3 Flashcards
What does aldosterone do to blood pressure?
Increase blood pressure
How does aldosterone raise blood pressure?
^ Na+/H2O reabsorption
What is reabsorption?
being reabsorbed into the blood. Is not excreted.
When aldosterone is released where is na+ reabsorbed?
distal tubule
What does ADH do to blood pressure?
increase bp
How does ADH increase blood pressure?
allows more water to be reabsorbed
What does ANP (atrial natriuretic peptide) hormone do?
Decreases blood pressure
If you have high blood osmolality what hormone is released?
ADH
What are the starling forces?
Hydrostatic pressure and osmotic pressure
What pressure draws blood into the veins/arteries?
osmotic pressures
What pressure pulls blood out of the arteries/veins?
hydrostatic pressure
where does reabsorption occur?
vasa recta in the kidney
What are the two layers of the kidney?
cortex (superficial) medulla (deep)
What is a oncotic pressure?
osmotic pressure
What kind of hormones are ADH and aldosterone?
ADH is peptide hormone Aldosterone is steroid hormone
