THORAX ABDOMEN AND PELVIS

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: -Conception typically happens in your fallopian tubes. This is where an egg goes after it leaves your ovary and where sperm wait for an egg. In some cases, fertilization can happen in your uterus once your egg has left your fallopian tubes.

Detailed explanation-4: -Fertilization occurs at ampulla isthamus junction due to paracrine signalling from tryosine kinase and lactoferrin which is instrumental in combining sperm with ovum.
