Q

What type of steroid hormones does the adrenal cortex secrete?

A
  1. Secretes mineralocorticoids
    • aldosterone- fluid balance
  2. Secretes glucocorticoids
    • Cortisol aids metabolism; when under stress;
    • aids in decreasing the immune response
  3. Secretes androgens & estrogens
    • androgens- male traits
    • estrogens- female traits
