Excretory System and the Nephron
Amoeba Sisters・2 minutes read
The excretory system, including the kidneys, is vital for maintaining osmotic balance and eliminating metabolic wastes through urine production. Various organs work together in the urinary system, with the nephron being the functional unit responsible for filtering blood, reabsorbing substances, and secreting others to regulate urine composition and concentration.
Insights
- The excretory system, including the kidneys, skin, liver, and lungs, is vital for maintaining the body's balance by eliminating waste and regulating osmotic levels.
- The nephron, with its components like the glomerulus, loop of Henle, and collecting duct, filters blood to create urine, regulating water and substance reabsorption, with hormonal control impacting urine concentration and medications like diuretics affecting osmotic values.
