The uterus is part of the internal genital organs and is the organ of pregnancy. It is a hollow muscle that receives the egg after fertilisation and where the pregnancy develops. It is a sort of “room” for the baby to grow before birth.

It is located above the vagina into which it opens via the cervix.

It also plays an important role during childbirth by its contractions to expel the baby.

The uterus is made up of 3 parts:

the lining: this is the highest part of the uterus. This is the thickness that serves as the implantation zone for the egg after fertilisation. In the absence of pregnancy, this mucous membrane is removed at the end of each cycle to give menstruation.

the serosa: this is the membrane surrounding the uterus

the muscularis: this is the muscle responsible for contractions during childbirth
