Identify and briefly describe the functions of the labeled glands of the human endocrine system. 

What will be an ideal response?


A. thyroid: regulates metabolic rate, growth and development and lowers blood calcium levels. 
B. parathyroid: raises blood calcium
C. adrenal glands: The adrenal cortex raises blood glucose levels, stimulates breakdown of proteins, regulates blood volume and pressure, produces male and female sex hormones, and mediates a long-term stress response. The adrenal medulla mediates a short-term stress response.
D. pineal gland: produces melatonin which is involved in the sleep-wake cycle and sexual development
E. hypothalamus: releases and inhibits hormones; regulates the anterior pituitary
F. pituitary gland: produces a variety of hormones such as ADH, oxytocin, TSH, ACTH, FSH, LH, PL, and GH
G. thymus: production and maturation of T lymphocytes
H. pancreas: produces insulin which regulates blood sugar and the formation of glycogen, and glucagon which raises blood sugar level and promotes glycogen breakdown
I. testis: produces the androgen testosterone which produces male sex characteristics
J. ovaries: produce estrogen and progesterone which produce female sex characteristics
