The renal tubule consists of 5 components: the proximal convoluted tubule, descending loop of Henle, ascending loop of Henle, distal convoluted tubule, and collection duct. The renal tubule will be broken down into 5 easy steps while using a phrase I came up with to help remember each part and the physiology that takes place. Last Modified Date: January 24, 2022 A diagram of a kidney. A distal convoluted tubule is a twisted, tube-like structure about 0.2 inches (around 5 mm) in length, found inside a part of the kidney known as a nephron. Each kidney contains many nephrons, and these are the functional units in which blood is filtered to form urine. Distal convoluted tubule - Tubulus contortus distalis. Anatomical Parts. The renal tubules, commencing in the renal corpuscles, present, during their course, many changes in shape and direction, and are contained partly in the medullary and partly in the cortical substance. distal convoluted tubule, with isolated macula densa specializa- well as in principal cells of CCT.

c) Distal Convoluted Tubule (DCT): Lies next to the glomerulus and similar to PCT, it secretes ions such as hydrogen, potassium, and NH3 into the filtered material while reabsorbing the HCO3-. Sodium ions along with water are reabsorbed in the DCT utilizing cellular energy and in presence of hormones.

The main function of the kidney is to filter fluid from the blood and concentrate the solution of waste materials which is passed out as urine. It can also control the levels of electrolytes and water that is lost in the urine or retained in the body thereby influencing blood volume and blood pressure. This ensures that the body is able to maintain a state of balance that is optimum for sustaining life (homeostasis). The kidney broadly has three main regions, an outer lying cortex, middle region known as the medulla and inner pelvis. The renal cortex and medulla is where the main processes of urine production occurs. The urine then accumulates in the renal pelvis and is directed towards the ureter, a narrow tube that carries urine from the kidney to the urinary bladder. The nephron is the main functional unit of the kidney which is responsible for filtering the blood and concentrating the solution to produce urine. In the process, macronutrients, electrolytes and the required amount of water are retained whil

The proximal convoluted tubule avidly reabsorbs filtered glucose into the peritubular capillaries so that it is all reabsorbed by the end of the proximal tubule. Distal convoluted tubules are paler and lack the brush border, which is more readily appreciated on PAS-stained sections.
