So this is basically the uterus. Now if the sperm cell is present inside the fallopian tube so after sexual intercourse if the sperm cell makes its way into the fallopian tube eventually it fuses, it combines with that excel to produce a zygote and that zygote begins to move and eventually makes its way into this organ known as the uterus. So the uterus is basically a pear shaped organ that is lined with a thick layer of smooth muscle. This layer right here that can basically contract during the process of childbirth. And it also contains a layer known as the endometrium. So a mucus layer, a mucous membrane known as the endometrium.
