- #1Write down the functional activity of the following parts, (a) Glomerulus ....... (b) Henle's loop .......... (c) Ureter ........ (d) Renal artery ........... (e) Urethra ............Ans : (a) Glomerulus is involved in the process of ultrafiltration. The liquid part of the blood which is plasma including urea, salts, glucose filters out from the glomerulus into the renal tubule. (b) Henle's loop is involved in reabsorption of water and sodium ions. (c) Ureter carries urine to the urinary bladder by ureteral peristalsis. (d) Renal artery supplied blood to the kidney. (e) Urethra is involved in the process of micturition i.e. expelling urine out of the body.
