Glands that sit on the top of the kidneys, has two sections
Yellowish in color due to presence of lipids, part of the adrenal gland
Steroid hormones produced by the adrenal cortex.
Hormones that affect the electrolyte composition of body fluids.
Stimulates the conservation of sodium ions by targeting cells that regulate the ionic composition of excreted fluids.
Hormones that affect glucose metabolism
Cortisol, Corticosterone, Cortisone

Hormone released by the kidneys, stimulates production of aldosterone.
Organ located in the mediastinum, posterior to the sternum, releases thymosins
Hormones released by the thymus, aid in lymphatic and immune defenses.
Cells in the testes that produces androgens
Hormone produced by the testes, most important androgen
Hormone secreted by the testes, inhibits secretion of FSH
Structures in the ovaries in which ova develop under stimulation by FSH.
Hormones produced by the cells surrounding the ova that support the maturation of the ova and the growth of the uterine wall.
The follicular cells reorganize into a ______ after ovulation
Hormone that accelerates the movement of fertilized eggs along the uterine tubes.
