Question

The correct path of transport of urine is ______

विकल्प

• Renal pelvis → minor calyx → major calyx → collecting duct

• Collecting duct → major calyx → minor calyx → renal pelvis

• Major calyx → minor calyx → collecting duct → renal pelvis

• Collecting duct → minor calyx → major calyx → renal pelvis

Answer 1

The correct path of transport of urine is Collecting duct → minor calyx → major calyx → renal pelvis.

Explanation:

Urine is formed by ultrafiltration, selective reabsorption, and secretion in the structural unit called a nephron. All nephrons open in a common collecting duct which in turn opens into a minor calyx. Major calyx, renal pelvis, and then into the ureter. urinary bladder, urethra, and expelled out by a process called micturition.
