Trace the path of filtrate and urine from the glomerulus to the external urethral opening

Nephron- - Collecting Tubule-Collecting Duct - Papillary duct - minor Calyx - Major Calyx - Renal Pelvis - Ureters - Bladder - Urethra

Explanation:

Urine is formed in nephron, basic unit of kidneys, through the process of filtration in glomerulus. Nephrons are connected with the collecting duct system of the kidney to a minor calyx. The collecting duct system consists of connecting tubule

, medullary collecting duct and papillary duct. The whole collecting duct system has a role in reabsorption and excretion.

Papillary ducts open at minor calyx, later in major calyx. Calyces open in pelvis, which is located inside hilum of kidney. Ureters travel out of kidney through hilum and pour urine into the urinary bladder. Urethra is the outlet that travels from bladder and when the bladder is ful sphincters control urethral opening to void urine outside the body.
