Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Where must fertilisation take place before there can be implantation?

A	Ovary
B	oviduct/fallopian tube
C	uterus
D	vagina

Explanation:

Detailed explanation-1: -Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.

Detailed explanation-2: -During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining-a process called implantation.

Detailed explanation-3: -The oviduct takes care of and modifies the sperm in such a way that it is able to fertilize. One of these modifications is the sperm pattern motility. Sperm within the epididymis are unmotile or poorly motile (inactivated).
