AAbout 4 cm long
BAbout 8 cm long
CAbout 12 cm long
DAbout 20 cm long
Answer & Solution
Correct answer: A. About 4 cm long
1. The female urethra runs about 4 cm from bladder to external orifice.
2. That short path is a weaker barrier to faecal bacteria than the much longer male urethra.
3. It is the best explanation offered for the greater incidence of urinary tract infection in women.
4. The 20 cm figure belongs to the male urethra, not the female one.
