The vas deferens receives duct from the seminal vesicle and opens into urethra as:
a. Epididymis
b. Ejaculatory duct
c. Efferent ductule
d. Ureter
The answer is the option (b) Ejaculatory duct
Explanation: The vas deferens is an essential continuation of the cauda epididymis, which measures about 40 cm. It starts slightly coiled but becomes straight as it enters the abdominal cavity through the inguinal canal. It passes over the urinary bladder, curves around the ureter, and merges with a duct from the seminal vesicle to form the ejaculatory duct. These ducts are responsible for storing and transporting sperm from the testes to the urethra.
