Fetus in the womb

Introduction (what it is)

The uterus is the largest organ that makes up the female reproductive system of most mammals, including humans.

Knowing the Uterus - Main Features and Function

There is a passageway for sperm deposited in the vagina to be able to reach the fallopian tube.

Its main function is to receive the fertilized egg and give it all the conditions for its development. The fertilized egg goes to the uterus still as an embryo, inside this organ, it becomes a fetus that will develop during pregnancy.

With respect to its anatomy, it has a dome shape at the top of the fallopian tubes (known as the bottom of the uterus), a slender central region (known as the body of the uterus) and a narrower part that has an opening for the vagina (known as the cervix). Its inner part is known as the uterine cavity.

It has an intermediate muscle layer - called the myometrium - that makes up the main portion of the uterine wall. In the innermost region of this wall is the endometrium, a richly vascularized tissue composed of blood capillaries; This is formed with the intention of nurturing the fetus, however, whenever the fertilization of the egg does not occur, it is discarded in menstruation.


After leaving the ovary, the egg can live for a maximum of 24 hours; however, he lives an average of ten hours. After this period he will go through a process known as autolysis, that is, he will self-destruct.
