Second stage of urine formation is called selective re-absorption. Why? |
Answer» The second stage of urine formation, tubular re-absorption, is called selective re-absorption because some substances such as glucose, amino acids, urea, salts and excess water are selectively reabsorbed back into the blood as urine is being filtered along the tubes. All components of plasma are not re-absorbed but only a few of them, hence, selective re-absorption. |
