Final answer:
Calculi, or kidney stones, can become lodged in various parts of the urinary system including the kidney, ureters, urinary bladder, or urethra, and the statement is true.
Step-by-step explanation:
The answer to the student's question is true. Calculi, or kidney stones, can indeed become lodged in the kidney, ureters, urinary bladder, or the urethra. Kidney stones are formed from minerals in the urine. When urine becomes concentrated, minerals can crystallize and stick together forming stones. These stones can vary in size and may cause severe pain and blockage if they are large enough.
The ureters carry urine from the kidney to the urinary bladder, and stones can travel through this system. However, when a stone is large, it may block the ureter and prevent urine from reaching the bladder, resulting in a condition known as renal colic.
