Diagram of kidney tubules
The nephron (fromGreek νεφρός – nephros, meaning "kidney") is the microscopic structural and functional unit of the kidney.It is composed of a renal
corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and an encompassing Bowman's capsule.The renal tubule extends from the capsule. The capsule and tubule are connected and are composed A gross section of the kidney reveals that the outer cortex has a somewhat different texture from the deeper medulla.This difference reflects the disposition of various portions of the many nephrons which comprise the kidney. The cortex consists of convoluted tubules together with the renal corpuscles.; The medulla consists of loops of Henle and collecting ducts. The kidneys filter about one-quarter (750-1000 pints) of the blood that is output by the heart daily. This blood is
sent to the body’s filter treatment plant, where it is … The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle.It can be further classifed into the proximal convoluted tubule (PCT) and the proximal straight tubule (PST The kidney has many roles, including: Elimination of metabolic waste; Fluid, electrolyte and acid-base balance; Conservation of nutrients: Glucose, amino acids Glucose: This is filtered and resorbed in the proximal convoluted tubules (PCT) by Na-dependent carrier transport mechanisms.The renal threshold differs amongst species: Valerie Lovelace Copyright September 2, 2005 In order to fully understand and appreciate the complexity of this process, we have to break it apart into steps, first Figure 1. This is a schematic diagram illustrating the kidneys' ability to separate particles in the blood in order to maintain optimal
body chemistry. Each of our kidneys contains over a million nephrons.They are the functioning unit of the kidneys. They remove waste from the body and produces urine.Each nephron is made up of two parts: a renal corpuscle and renal
