What Are The Two Mechanisms Of Tubular Reabsorption?

What Are The Two Mechanisms Of Tubular Reabsorption? Mechanisms by which substances move across membranes for reabsorption or secretion include simple diffusion, facilitated diffusion, active transport, secondary active transport, and osmosis. Simple diffusion moves a substance from a higher to a lower concentration down its concentration gradient. What is the process of tubular reabsorption? Tubular

Why Does Selective Reabsorption Occur At The Proximal Convoluted Tubule?

Why Does Selective Reabsorption Occur At The Proximal Convoluted Tubule? Selective reabsorbtion occurs in the PCT (proximal convoluted tubule). The PCT is highly permeable meaning it is easy for molecules to diffuse through it. How does reabsorption occur in the proximal convoluted tubule? Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into
