The glomerulus is the main filtering unit of the kidney. It is formed by a network of small blood vessels ( capillaries) enclosed within a sac called the Bowman's capsule. The space inside the capsule that surrounds the glomeruli is known as the Bowman's space. Each glomerulus is located at the beginning of the nephron.

nephron. noun. neph· ron ˈnef-ˌrän. : one of the functional units of the kidney that filters the blood, selectively reabsorbs substances (as glucose, ions, and amino acids), and excretes nitrogenous waste (as urea) and excess water and salts in the form of urine.

A nephron is the basic structural and functional unit of the kidneys that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine. Its function is vital for homeostasis of blood volume, blood pressure, and plasma osmolarity.

The structure of nephron comprises two major portions: Renal Tubule Renal Corpuscle

A nephron is the basic structural and functional unit of the kidney. They are the microscopic structure composed of a renal corpuscle and a renal tubule. The word nephron is derived from the Greek word – nephros, meaning kidney. There are about millions of nephrons in each human kidney. Structure of Nephron

The functioning of nephron has 3 mechanism to convert blood into urine which are. Filtration Reabsorption Secretion; After entering the kidney the renal artery gets divided into many small divisions until it reaches the smallest one that enters the nephron.

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.
