1. Peptide hormones Insulin has a profound influence or carbohydrate metabolism. It facilitates entry of glucose and other sugars into the cells by increasing penetration of cell membranes and augmenting phosphorylation of glucose. This decreases glucose concentration in blood and insulin is commo..

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 horm..

Adrenal cortex is a pale yellowish pink tissue, which shows three concentric regions outer, middle and inner. Each region produces its own set of hormones. It secrets a number of steroid hormones which are broadly classified into three groups such a..

1) They are the chief energy storers of the body, which form an important source of energy during starvation or other emergencies. 2) Fats play a role in the absorption of fats soluble vitamins like vitamins A, D, E and K. 3) Steroids like cholesterol which are related to fats are import..

Endocrine system consists of many endocrine or ductless glands, which secrete hormones into the blood. Hormones are information molecules, which regulate specific physiological processes in the target cell, tissues or organs. Hormones co-ordinate the activities of different organs and tissu..

Bile pigments (biliverdin and bilirubin) are produced as a result of break down of haemoglobin in the worn out red blood cells in the liver and excreted with the bile into the duodenum and removed along with the faeces. Liver also excretes cholesterol, various inactivated products of steroid..
