We have discussed many dramatic effects of hormone, for instance, testosterone. Yet, its concentration in the plasma of adult human male is only 30 to 100 ng per ml. How can hormones in such tiny quantities have such widespread and selective actions? Unlike catecholamine and peptide hormones, ..

It is the largest gland and is found in the upper part of the abdomen on the right side just below the diaphragm. Its secretion is called bile juice. It is alkaline and rich in organic (steroid) salts called the bile salts. The alkaline nature serves to neutralize the acidic pH of t..

These are secreted by both middle and inner layers of the adrenal cortex. Their secretion is believed to be stimulated by corticotropin of the anterior pituitary. They include steroids, which stimulate the development of external sexual characters or secondary sexual characters. They con..

The ovaries lie in the abdomen and are the female reproductive organ. They secrete three steroid female sex hormones Oestrogens, progesterone and relaxin . Ovaries are two almond-shaped glands placed one on each side of the uterus, below the uterine tubes attached to the back of the bro..
