Final answer:
Option 1). The medical terms cali/o and calic/o denote the kidney's calyx, which collects urine before it passes into further urinary structures.
Step-by-step explanation:
The calyx or calices, which are anatomical features of the kidney, are referred to by the medical terms cali/o and calic/o. The kidney's funnel-shaped structure called the calyx (plural: calyces) gathers urine before it enters the renal pelvis and ureter. It refers to the area of the renal pelvis that is cup-shaped and where urine gathers before to being sent to the bladder. The Latin word "calix," which meaning cup, is the source of this noun. It has nothing to do with the other choices, which include calisthenics, calories, and calcium—all of which pertain to physical activities, energy units, and chemical elements, respectively.
