Adrenal cortex
Identify the part of the adrenal gland indicated by "E."
Adrenal medulla
If you have a homeostatic imbalance of excessive loss of Na+ in extracellular fluids, what hormone will help restore that balance?
Aldosterone

Glucocorticoids
Androgens secreted by the adrenal cortex belong to which category of hormones?
Gonadocorticoids
Which of the following hormones is secreted by the adrenal gland?
