Detailed explanation-1: -Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.

Detailed explanation-2: -The nephron includes a filter called glomerulus, a tubule. The nephron includes a filter called the glomerulus, and tubule.

Detailed explanation-3: -The filtration of blood is carried out in renal corpuscle. Glomerulus and Bowman’s capsule together form the renal corpuscle. Glomerulus is a group of blood capillaries that is present in the Bowman’s capsule of nephrons and is the seat, where the process of ultrafiltration takes place.

Detailed explanation-4: -The primary route in which the body eliminates substances is through the kidneys. The main function of the kidney is the excretion of body wastes and harmful chemicals into the urine. The functional unit of the kidney responsible for excretion is the nephron.

Detailed explanation-5: -The nephrons of the kidneys process blood and create urine through a process of filtration, reabsorption, and secretion. Urine is about 95% water and 5% waste products. Nitrogenous wastes excreted in urine include urea, creatinine, ammonia, and uric acid.
