Question

Describe the autonomic and hormonal control of the vasculature

Answer 1

Answer:

The vasculature is nothing but the vascular system of the body. It is regulated partly by autonomic (neural) and hormonal factors. Neural mechanisms primarily involve sympathetic adrenergic and parasympathetic cholinergic branches of the autonomic nervous system. The sympathetic system stimulates the heart and constricts blood vessels resulting in a rise in arterial pressure. The parasympathetic system depresses cardiac function and dilates selected vascular bed. There are several very important humoral mechanisms including circulating catecholamines, the renin-angiotensin system, vasopressin (antidiuretic hormone), atrial natriuretic peptide, and endothelin. Each of these humoral systems directly or indirectly changes the vascular function.
