Explanation / Answer

21.b growth of endometrial tissue outside the uterus

Explanation : The term is endometriosis which when split into two gives you 'endometri' (standing for endometrial /endometrium) and the suffix 'osis' which stands for diseased state physiological /pathological increase.

Therefore the correct option would be 'b'

22.b

Explanation : vasectomy derived from modern Latin 'vas' for Vasa deferens and 'ectomy' for cutting.

As the function of Vasa deferns is directing sperms to urethra after reaching epididymis and vasectomy means surgical removal of the same and thus stopping the function of propelling sperms into the urethra the correct answer is 'b'

23.b

Explanation : For the process of spermatogenesis i. e. the process of sperms development it is essential that the temperature in the testicles be lower than that of the entire body. Rise in temperature leads to decrease in sperms production over the course of time thus leading to infertility.

24.b

Explanation : Seminiferous tubules is where the spermatozoa (male gamete) is produced and differentiated to mature sperms. The sperms are stored in epididymis. During sexual activity the sperms from epididymis reach the blind tube called Vasa deferns and finally urethra.
