Question

Common duct formed by union of vas-deferens and duct from seminal vesicle is &ndash;a)Urethrab)Tunica-vasculosac)Ejaculatory ductd)Spermatic ductCorrect answer is option 'C'. Can you explain this answer?

Answer

The common duct formed by the union of vas-deferens and duct from seminal vesicle is the ejaculatory duct.
The ejaculatory duct is an important structure in the male reproductive system that is responsible for transporting semen. Here is a detailed explanation of the common duct and its formation:
1. Vas-deferens: The vas-deferens, also known as the ductus deferens, is a long, muscular tube that connects the epididymis to the ejaculatory duct. It carries sperm from the testes to the urethra.
2. Seminal vesicle: The seminal vesicle is a gland located behind the bladder that produces seminal fluid. This fluid contains various substances that nourish and protect the sperm.
3. Formation of the ejaculatory duct: The vas-deferens and the duct from the seminal vesicle join together to form the ejaculatory duct. The union occurs in the prostate gland, which is a walnut-sized gland located below the bladder and in front of the rectum.
4. Location and function of the ejaculatory duct: The ejaculatory duct passes through the prostate gland and opens into the urethra. It plays a crucial role in the ejaculation process by propelling sperm and seminal fluid into the urethra, from where it can be expelled from the body during sexual intercourse.
In conclusion, the common duct formed by the union of the vas-deferens and duct from the seminal vesicle is the ejaculatory duct. It serves as a conduit for the transport of sperm and seminal fluid during ejaculation.
