Urinary System - Anatomy and Physiology made simple.
Brief Overview: Urinary System is one of the eleven body systems and functions to eliminate waste and helps the body to maintain its internal environment (homeostasis) like the pH (acid-base balance) and electrolyte (Sodium, Potassium, Magnesium, Chloride, Bicarbonate, Phosphorus etc.,) levels, fluid balance along with blood pressure and stimulates the bone marrow to help form new red blood cells. In males it also works along with the reproductive system in forming the passage way for the semen to be ejaculated. The two main hormones that are secreted by the kidneys are the Renin (Renin-Angiotensin-Aldosterone System to maintain blood pressure) and the Erythropoietin (to stimulate Red Blood Cell production). Kidneys also convert part of Calcidiol to Calcitriol which is the active form of Vitamin D which plays a key role in Calcium metabolism and keeping bones healthy.
