Biology
Given below is a diagram of two systems together in the human body.
(a) Name the systems.
(b) Name the parts numbered 1-10.
(c) Describe the functions of the parts 3, 4, 5 and 6.
(d) What will happen if the part 3 on both sides gets blocked?
Answer
(a) Excretory system and Female Reproductive system.
(b) The parts numbered 1-10 are:
- 1 → Kidney
- 2 → Ureter
- 3 → Fallopian Tube
- 4 → Oviducal Funnel
- 5 → Ovary
- 6 → Uterus
- 7 → Urinary Bladder
- 8 → Cervix
- 9 → Vagina
- 10 → Vulva
(c) Functions of the parts are:
- Fallopian Tube (part 3) — The fallopian tubes carry the ovum released from the ovary to the uterus.
- Oviducal Funnel (part 4) — It is the funnel shaped distal end of the ovary which picks up the released ovum and pushes it further on its passage into the fallopian tube.
- Ovary (part 5) — Ovary produces female gametes i.e. ova.
- Uterus (part 6) — Uterus allows the growth and development of the embryo.
(d) If fallopian tube (part 3) on both sides gets blocked, the ovum released by the ovary will not be pushed into the oviduct and hence, there will be no possibility of fertilisation.
