Reabsorption of the metabolic products along the kidney tubules is made possible by the

The reabsorption of metabolic products in the kidney tubules is made possible by the presence of a network of capillaries around the convoluted tubules. The capillaries around the tubules allow the metabolic products to diffuse from the tubules into the bloodstream, where they can be transported to other parts of the body for use or excretion. The convoluted nature of the tubules also increases the surface area for absorption, while the joining of the main collecting tubules to the kidney tubules allows for the proper regulation and elimination of excess metabolic waste.
