Question

Describe the structure and function of human kidney

Answer 1

Kidney: The kidney is a major part of the excretory system. They are bean-shaped and located in the abdominal area, on each side of the trunk. The kidneys control the water and minerals the body absorbs. They act like filters. Blood enters the kidneys with waste. In the kidney, blood is filtered and purified. The waste remains in the kidneys, and the purified blood is transported to other parts of the body. Waste and other materials are then sent into the urinary tract through the ureter. The ureter contains urine. Urine is made from 95% water, 2.5% urea, and 2.5% other waste. The kidney is the structural and functional unit of the kidney that filters excess waste in the blood, urea and water. As blood passes through the nephron, it is purified and filtered in the nephron. Useful ingredients (such as sugar, salt, and amino acids) are sent back to the kidneys for reabsorption. Sometimes urine shows abnormal components. This indicates that the person may be suffering from a certain disease or infection. In this case, the disease can be determined through a medical test or a urine test. Sometimes blood appears in the urine, which indicates a serious infection or kidney damage.
