What is the proximal tube?
The proximal tube is part of the kidney responsible for filtering glucose, salt, amino acids, potassium, phosphates, vitamins and minerals and urea in the blood and re -introducing the blood back into the blood supply. It consists of two parts: Pars Convoluta and Pars Recta. As the name suggests, it is, as its name, intricate, and it is the initial part of the proximal tubule, reabsorbing water, salt and the above nutrients and by -products, and producing what is called organic cations and anions such as creatinine, as well as hydrogen ions. Pars Recta, a direct descending part, also filter all these and also a bicarbonate for blood pH regulation. The proximal tubule works with other parts of the kidney tubule system and is a member of what is called the collection channel. The proximal tube receives nutrients from Bowman's capsules through small arteriole holes under pressure; These holes are too small to make the proteins pass. The proximal tube can produce anhydrous ammonia to clean the protons, produce a hydroOgenujičitanitane ions as needed to regulate pH and even the main contributor in blood pressure regulation.
The proximal tube acts mainly as an absorption and re -assembly line and produces ions such as the ion of bicarbonates and organic acids such as creatinine, to the filtrate. Sodium transport carries filtrate via tubul and filtration is essentially isotonic, where mechanisms that are dependent on energy along the line absorb and reabsorb nutrients to achieve the correct balance in the blood. Most of the re -absorption takes place in the Rect of Pars, where high concentrations of nutrients are collected to and cause osmotic re -preparation of water.
When the filtrate is accepted from Bowman's capsule, the epithelial cells in the proximal tubule are transport for movement and re -absorption of glucose and amino acids, as well as most water and a certain urea. Mitochondria also transports nutrients along where bufroVaca phosphates can regulate urine pH. Proton pumps then disperse the protons into the urine for excretion.
The most common form of kidney cancer is the kidney cancer, which usually occurs in the proximal tubule. In addition, damage to toxins or some antibiotics, pigments and sepsis may damage toxins or some antibiotics, pigments and sepsis. Disorders in absorption and re -absorption may be caused by a disease known as Hartnup's disease, a congenital maladaptation of a gene that causes victims to be unable to absorb amino acids and thus fail to prosper. Other diseases are ischemia, which is a reduction in blood supply, causing tissue necrosis and Cells robs oxygen and nutrition from blood and interstitial nephritis, which is an inflammation of tissues surrounding the proximal tube.
