They block release of noradrenaline at sympathetic nerve endings and therefore cause vasodilation and reduced peripheral vascular resistance.

The absorbing membrane for nutrients and drugs is the mucous membrane of the epithelial buys metformin online cheap lining the gastrointestinal tract. General factors affecting diffusion across cell membranes, considered above, apply in addition to the pH of gastrointestinal contents: surface area of the gastrointestinal tract; gastric emptying and intestinal transit time; blood flow from the gastrointestinal tract; plasma protein binding; active transport mechanisms and drug formulation.

Hormones are chemicals that are released into the blood stream where they travel to distant tissues and their sites of action.
As with any body system, there is the possibility of disease and malfunction: glands can secrete too much of their hormones; cells in tissues can have altered sensitivity to hormones; feedback control systems can break down.
