The renal corpuscle is a blood-filtering part of the nephron and is located in the cortex. The renal tubule extends from the renal corpuscle to the medulla into the loop of Henle and then returns back to the cortex. Finally, the renal tubule flows with its distal end into its collecting duct, which is common to several nephrons.
The proximal tubule as a part of the nephron can be divided into an initial convoluted portion and a following straight (descending) portion. [12] Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries, including 80% of glucose, more than half of the filtered salt, water and all filtered ...
Its chief function is to regulate the concentration of water and soluble substances like sodium by filtering the blood, reabsorbing what is needed and excreting the rest as urine. In the first part of the nephron, Bowman's capsule filters blood from the circulatory system into the tubules. Hydrostatic and osmotic pressure gradients facilitate ...
The major functions of these lining cells are the reabsorption of water and small molecules from the filtrate into the blood, and the secretion of wastes from the blood into the urine. Proper function of the kidney requires that it receives and adequately filters blood.
The distal tubule of the mammalian kidney is the portion of the nephron located between the macula densa region and the cortical collecting tubule. It consists of various subsegments that differ in structure and function, and it is responsible for reabsorbing 5-10% of filtered sodium and chloride under normal circumstances, as well as playing a ...
The mesonephros acts as a structure similar to the kidney that, in humans, functions between the sixth and tenth weeks of embryological life. Despite the similarity in structure, function, and terminology, however, the mesonephric nephrons do not form any part of the mature kidney or nephrons.
Uriniferous tubules: any of the small tubules that are the excretory units of the vertebrate kidney; Uveoscleral pathway: a tubule that drains excess aqueous humor; Vasa efferentia: convoluted tubules that lead from the rete testis to the vas deferens and form the head of the epididymis [2]
The main function of the glomerulus is to filter plasma to produce glomerular filtrate, which passes down the length of the nephron tubule to form urine. The rate at which the glomerulus produces filtrate from plasma (the glomerular filtration rate ) is much higher than in systemic capillaries because of the particular anatomical ...
