Renal System Functions: Blood Pressure Regulation and Acid/Base Balance

Question 1

The adrenal glands release epinephrine and norepinephrine. These hormones would respond to what type of receptors?

Answer 1

Adrenergic receptors

Question 2

What type of receptor does acetylcholine respond to?

Answer 2

Cholinergic receptors

Question 3

What happens to blood pressure when you lose blood?

Answer 3

Blood pressure drops

Question 4

How does the hypothalamus impact blood pressure? What about the kidney? What is the name of this system?

Answer 4

Renin-angiotensin-aldosterone-system (RAAS)
The hypothalamus alters the sympatheric nervous activity.
The Kidneys filter blood and remove excess H2O and Na+.

Question 5

What 3 things cause the release of renin?

Answer 5

Decreased blood pressure
Decreased Na+ levels
Increase in Sympathetic Nervous Activity

Question 6

What does renin do?

Answer 6

Control BP, Na+/K+ levels, and fluid homeostasis

Question 7

What is the effect of angiotensin 2?

Answer 7

Increased blood pressure

Question 8

What is Alkalosis?

Answer 8

Basic (pH >7.45)

Question 9

What is Acidosis?

Answer 9

Acidic (pH <7.35)

Question 10

What are things that trigger/cause an increase/decrease in pH?

Answer 10

Increased or decreased amounts of CO2 (respiratory)
Changes in amount of H+ and HCO3- (metabolic)

Question 11

How does the body respond to an increase/decrease in pH?

Answer 11

Adjusting breathing rates (respiratory)
Reabsorption or secretion of H+ and HCO3- (metabolic)
