What are the individual unit of kidney called?

The individual unit of the kidney is called the nephron. Each kidney contains millions of nephrons, which are responsible for filtering waste products from the blood and producing urine. The nephron is made up of several parts, including the glomerulus, proximal convoluted tubule, loop of Henle, and distal convoluted tubule. The glomerulus is a small cluster of blood vessels that filter waste products from the blood. The proximal convoluted tubule is a long, winding tube that reabsorbs water and nutrients from the filtered fluid. The loop of Henle is a U-shaped structure that helps to concentrate the urine. The distal convoluted tubule is responsible for fine-tuning the composition of the urine before it is excreted from the body.
