Categories : Kidney anatomy. Each nephron is a long tubule or extremely…. In the presence of parathyroid hormonethe distal convoluted tubule reabsorbs more calcium and secretes more phosphate. The hypertonicity of the medulla and therefore concentration of urine is determined in part by the size of the loop of Henle. Your ureter carries urine from the kidney to your bladder. The structure and function of the epithelial cells lining the lumen change during the course of the nephron, and have segments named by their location and which reflects their different functions.

    The left nephron is labelled. Nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood. The nephron is the functional unit of the kidney. The glomerulus and convoluted tubules of the nephron are.
    The collecting duct system begins in the renal cortex and extends deep into the medulla.

    Juxtamedullary nephrons start low in the cortex near the medulla and have a long loop of Henle which penetrates deeply into the renal medulla: only they have their loop of Henle surrounded by the vasa recta.

    Some diseases of the nephron predominantly affect either the glomeruli or the tubules. As the urine travels down the collecting duct system, it passes by the medullary interstitium which has a high sodium concentration as a result of the loop of Henle's countercurrent multiplier system. The JGA is located between the thick ascending limb and the afferent arteriole.

    The renal tubule is the portion of the nephron containing the tubular fluid filtered through the glomerulus.

    The nephron is the functional unit of the kidney, with each nephron being comprised of the following components. Each nephron is made up of two parts: a renal corpuscle and renal tubules Schematic diagram of the nephron demonstrating the site of action of diuretics. The renal cortex is granular due to the presence of nephrons, the functional unit of the kidney. The medulla consists of multiple pyramidal tissue.
    At the end of the tubule, the remaining fluid— urine —exits: it is composed of water, metabolic wasteand toxins.

    A nephron consists of three parts: a renal corpuscle, a renal tubule, and the associated capillary network, which originates from the cortical radiate arteries.

    When aldosterone is present, more sodium is reabsorbed and more potassium secreted.
