Glands A gland is an organ which produces and releases substances that perform a specific function in the body. What is a gland? Male testes are egg shaped glands located in the sac like scrotum, and serve two main functions: i The production of sperm cells, and ii The secretion of testosterone.
Testosterone is the masculizing hormone inducing male secondary sexual characteristics after puberty. Female ovaries are two almond shaped glands on each side of the uterus.
They have three main functions; i Containing immature ova eggs , ii The secretion of oestrogen, and ii the secretion of progesterone. Ostrogen is secreted by the adrenal cortex as well as the ovaries, and is present in the blood of all females from puberty through to the menopause. This induces and maintains female secondary sexual characteristics. Progesterone works on the uterus to prepare it for the implantation of a fertilised ovum egg.
It causes the development of the breasts, and is essential for the complete development of the maternal proportion of the placenta. Giantism too much HGH is secreted before puberty. Dwarfism is caused by a lack of HGH before puberty. Diabetes Mellitus is a condition with under-secretion of insulin, causing the cells to loose their permeability to glucose preventing them from getting sugar needed for energy.
Sugar remains in the blood and often the body will try and remove this leading to a high sugar content in the urine, causing polyuria passing of large volumes of urine and polydipsia excessive thirst.

Paul Andersen Paul Andersen explains the major elements in the endocrine system. The hormones then diffuse into nearby capillaries and are transported throughout the body in the blood.
The endocrine and nervous systems often work toward the same goal. Both influence other cells with chemicals hormones and neurotransmitters. However, they attain their goals differently. Neurotransmitters act immediately within milliseconds on adjacent muscle, gland, or other nervous cells, and their effect is short-lived.
In contrast, hormones take longer to produce their intended effect seconds to days , may affect any cell, nearby or distant, and produce effects that last as long as they remain in the blood, which could be up to several hours.
