Question

Mark the odd term in each series: Give category for the rest of terms.

Vasa efferentia; epididymus; vas deferens; seminal vesicle.

Answer 1

Seminal vesicle

1. Vasa efferentia are small tubules that originate from the seminiferous tubules and ultimately fuse to form the epididymus.
2. Epididymus is the highly - coiled structure originating from the seminiferous tubules where the sperms are stored, concentrated and mature.
3. Vas deferens originates from the testis and transports mature sperm from the epididymus to the urethra.
4. So, vasa efferentia, vas deferens, and epididymus comprise the duct system in the male reproductive system.
5. The seminal vesicle is an accessory gland associated with the male reproductive system.

Hence, the seminal vesicle is the odd one out and the others form the ducts of the male reproductive system.
