Basically, a nephron comprises a renal tubule and blood vessels. The renal tubule expands into a cup-shaped structure called the Bowman's Capsule, which contains a ball of capillaries known as the Glomerulus. The Glomerulus is the primary structure of the filtering process.
From Wikipedia, the free encyclopedia. Renal glucose reabsorption is the part of renal physiology that deals with the retrieval of filtered glucose, preventing it from disappearing from the body through the urine. If glucose is not reabsorbed by the kidney, it appears in the urine, in a condition known as glucosuria.This is associated with diabetes mellitus. Firstly, the glucose in the proximal tubule is co-transported with sodium ions into the proximal convoluted tubule walls.Some (typically smaller) amino acids are also transported in this way. Once in the tubule wall, the glucose and amino acids diffuse directly into the blood capillaries along a concentration gradient.This blood is flowing, so the gradient is maintained. Lastly, sodium/potassium ion active transport pumps remove sodium from the tubule wall and the sodium is put back into the blood.nce in the tubule wall, the glucose and amino acids diffuse directly into the blood capillaries along a concentration gradient.
