Ayesha Joshi answered
The uterus, also known as the womb, is responsible for nourishing and supporting a developing fetus during pregnancy. It provides the necessary environment for the implantation and growth of the embryo, and later the fetus, until birth.

The process of spermatogenesis primarily occurs in which of the following locations?
  • a)
    Epididymis
  • b)
    Seminal vesicles
  • c)
    Testes

    Uterus
  • b)
    Ovaries
  • c)
    Fallopian tubes
  • d)
    Vagina
Correct answer is option 'C'. Can you explain this answer?

Ayesha Joshi answered
The fallopian tubes, also known as the oviducts, are the site of fertilization in the female reproductive system. After ovulation, the released egg travels through the fallopian tubes, where it can be fertilized by sperm.

Fertilization of an egg by a sperm typically occurs in which of the following locations?
  • a)
    Uterus
  • b)
    Fallopian tubes
  • c)
    Cervix
  • d)
    Vagina
Correct answer is option 'B'. Can you explain this answer?

Ayesha Joshi answered
Fertilization, the fusion of a sperm and an egg, typically occurs in the fallopian tubes. After ovulation, the released egg travels through the fallopian tubes, where it may encounter sperm and undergo fertilization. The fertilized egg then continues its journey to the uterus for implantation.
