what hormones do the kidneys produce and what are their function
The kidneys remove waste products and excess water from the body and so help to regulate blood pressure. They activate vitamin D, which helps to maintain strong bones, and produce erythropoietin, a hormone that is vital for the production of red blood cells.Each kidney contains 1.0-1.5 million small tubes called nephrons. The kidneys filter blood through a network of small blood vessels called the glomerulus.his helps to control blood pressure. In addition to making hormones, the kidneys also respond to a number of hormones including vitamin D, aldosterone, prostaglandins, cortisol, parathyroid hormone and calcitonin.
