Solution
In a nephron, the blood .enters by afferent arteriole and is filtered through the glomerulus. The filtrate is passed into the Bowman’s capsule; by the process called ultrafiltration. The filtrate contains useful products like glucose, amino acids, salts, etc. The plasma proteins, blood corpuscles, and platelets are retained in the glomerular mass. The filtrate now passes through Henle’s loop where selective reabsorption of useful products takes place but urea and uric acid are not absorbed. Now the excretory substances are secreted by proximal and distal convoluted tubule and urine is formed.
