Each renal tubule is divided into a proximal tubule, loop of Henle, and distal convoluted tubule. Renal Tubule StructureRenal tubules are a duct system beginning at the Bowmen's capsule in the cortex, looping through the renal medulla, and returning to the cortex to connect to the collecting duct system. The glomerular filtration rate is a measure of kidney function. The glomerulus is a capillary extension, a small network of thin blood vessels, receiving blood from the renal circulation. The Bowman's capsule is a double membrane that cups the glomerulus.
Renal Corpuscle StructureThe renal corpuscle is the initial filtering component of the nephron and is made up of two structures known as the glomerulus and Bowman's capsule. There are two main parts of a nephron: the renal corpuscle and renal tubule. The approximately 1 million nephrons in each human kidney form 10-20 cone-shaped tissue units called renal pyramids that span both the inner and outer portions of the kidney, the renal medulla and renal cortex. Each nephron is made of intricately interwoven capillaries and drainage canals to filter wastes, macromolecules, and ions from the blood to urine. The basic structural and functional units of the kidneys are the nephrons. The kidney is responsible for maintaining fluid balance within the body. They consist of a network of tubules and canals specialized in filtration. Nephrons are the basic structural and functional units of the kidney.
