Label the parts marked 2 and 4. Mention the function of part 5.
Topic: Ureter, urinary sphincter and urethra
Answer
2 — URETER 4 — URINARY SPHINCTER
Part 5 is the URETHRA. Its function is to carry urine from the urinary bladder to the OUTSIDE of the body. (In the male it also carries semen.)
THE SPELLING DISTINCTION costs marks every year and both words appear in this one question: URETER — kidney to bladder (two of them, one per kidney) URETHRA — bladder to outside (only one)
The URINARY SPHINCTER is the ring of muscle at the neck of the bladder. It stays contracted, holding urine in, until voluntarily relaxed — which is why prostate surgery near it can cause incontinence, as the 2026 paper describes.
