Final Answer:
The major calyx in the inner kidney is a larger structure that collects urine from several minor calyces before draining into the renal pelvis.
Step-by-step explanation:
Within the kidney, the minor calyces gather urine from individual renal papillae. Several minor calyces converge to form larger structures called major calyces. These major calyces serve as a collection point, merging urine from multiple minor calyces before transporting it further. Ultimately, the major calyces combine to form the renal pelvis, a funnel-shaped area in the kidney that acts as a reservoir for urine before it travels to the ureter and exits the kidney.
The major calyx plays a pivotal role in the urinary system by efficiently channeling urine from the minor calyces to ensure its smooth flow toward the renal pelvis. Its function is essential in maintaining proper kidney function and the elimination of waste products from the body through the urinary tract.
