GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The female reproductive system derives from four origins: mesoderm, primordial germ cells, coelomic epithelium, and mesenchyme. The uterus forms during Mullerian organogenesis accompanied by the development of the upper third of the vagina, the cervix, and both fallopian tubes.

Detailed explanation-3: -Pregnancy is the term used to describe the period in which a fetus develops inside a woman’s womb or uterus. Pregnancy usually lasts about 40 weeks, or just over 9 months, as measured from the last menstrual period to delivery.
