PATHOLOGY

Detailed explanation-1: -The kidney plays a central role in the regulation of arterial blood pressure. A large body of experimental and physiological evidence indicates that renal control of extracellular volume and renal perfusion pressure are closely involved in maintaining the arterial circulation and blood pressure.

Detailed explanation-2: -The kidneys help to control blood pressure by removing water and salt from the blood, as well as producing hormones that are involved in controlling blood pressure.

Detailed explanation-3: -The constriction of arterioles increases resistance, which causes a decrease in blood flow to downstream capillaries and a larger decrease in blood pressure. Dilation of arterioles causes a decrease in resistance, increasing blood flow to downstream capillaries and a smaller decrease in blood pressure.

Detailed explanation-4: -Healthy kidneys respond to a hormone called aldosterone which is produced in the adrenal glands, to help the body regulate blood pressure.
