Packet 15 - Endocrine System

Question 1

Function of Adrenal Cortex Hormones

Increases Na, which also causes water retention. Also lowers K.

a. ) Mineralocorticoids (aldosterone)
b. ) Glucocorticoids (cortisol)
c. ) Adrenal sex hormones (androgens)

Answer 1

Mineralocorticoids (aldosterone)

• increases Na → increases water retention
  
  • increases BP (secondary hypertension)
• decreases K

Question 2

Function of Adrenal Cortex Hormones

Increases blood glucose levels, breaks down proteins and fats, decreases inflammatory response (but also decreases immune response). Increases Na and water, and decreases K.

a. ) Mineralocorticoids (aldosterone)
b. ) Glucocorticoids (cortisol)
c. ) Adrenal sex hormones (androgens)

Answer 2

Glucocorticoids (cortisol)

• Increases blood glucose.
• breaks down proteins and fats.
• decreases inflammatory response (but also decreases immune response).
• Increases Na and water, and decreases K.

Question 3

Function of Adrenal Cortex Hormones

The hypothalamic-pituitary feedback mechanism regulates which two types of hormones?

a. ) Mineralocorticoids (aldosterone)
b. ) Glucocorticoids (cortisol)
c. ) Adrenal sex hormones (androgens)

Answer 3

cortisol and androgens

Glucocorticoids (cortisol)

• Increases blood glucose.
• breaks down proteins and fats.
• decreases inflammatory response (but also decreases immune response).
• Increases Na and water, and decreases K.

Adrenal sex hormones (androgens)

Affects secondary sex characteristics.

Question 4

Function of Adrenal Cortex Hormones

The RAA mechanism regulates which hormone?

a. ) Mineralocorticoids (aldosterone)
b. ) Glucocorticoids (cortisol)
c. ) Adrenal sex hormones (androgens)

Answer 4

Mineralocorticoids (aldosterone)

• increases Na → increases water retention
  
  • increases BP (secondary hypertension)
• decreases K

Question 5

Function of Adrenal Cortex Hormones

Type of adrenal sex hormone.

a. ) Aldosterone
b. ) Cortisol
c. ) Androgens

Answer 5

Androgens (adrenal sex hormone)

Question 6

Function of Adrenal Cortex Hormones

Type of glucocorticoid hormone.

a. ) Aldosterone
b. ) Cortisol
c. ) Androgens

Answer 6

Cortisol (glucocorticoids)

Question 7

Function of Adrenal Cortex Hormones

Affects secondary sex characteristics.

a. ) Mineralocorticoids (aldosterone)
b. ) Glucocorticoids (cortisol)
c. ) Adrenal sex hormones (androgens)

Answer 7

Adrenal sex hormones (androgens)

Affects secondary sex characteristics.

Question 8

Function of Adrenal Cortex Hormones

Type of mineralocorticoid hormone.

a. ) Aldosterone
b. ) Cortisol
c. ) Androgens

Answer 8

Aldosterone (mineralocorticoids)
