Second stage of urine formation is called selective re-absorption. Why?
Answers
Explanation:
Therefore, the kidneys selectively reabsorb only those molecules which the body needs back in the bloodstream. The reabsorbed molecules include: all of the glucose which was originally filtered out. as much water as the body needs to maintain a constant water level in the blood plasma.
Selective reabsorption is the process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron.[1] Selective reabsorbtion occurs in the PCT (proximal convoluted tubule). The PCT is highly permeable meaning it is easy for molecules to diffuse through it.
