WHAT IS THE UTERUS?

The uterus is also known as the womb. The uterus is the main place where the fetus grows. Thus, the uterus constitutes a vital part of the female reproductive system. The uterus is pear-shaped and hollow. The diameter of a normal uterus is several centimeters.

UTERUS FORMATION

Mostly muscles known as myometrium constitute the uterus. The most interior portion of myometrium is called ‘Junctional zone'. When this zone thickens during pregnancy; the process is known as adenomyosis. The uterus cavity lining is called endometrium. This lining is peeled off during menstruation. Parametrium is the surrounding tissues which are generally loose.

UTERUS LOCATION

The uterus is located between the rectum and the bladder within the pelvic region. The uterus is the place where the baby grows up.

UTERUS SECTIONS

The eight different sections of a uterus are cervix, corpus, fundus, fallopian tubes, ovaries, tissues, endometrium and myometrium.
The first three basically refer to various portions of the uterus. The cervix is the lower portion of the uterus. The corpus is the middle portion of the uterus. It is broad in size and expanse. The fundus is the top portion of the uterus. It remains in the shape of a dome.
The others five are ancillary sections of the uterus. The fallopian tubes stretch till the ovaries. They stretch from the two top sides of the uterus.
The tissues are integral linings of the uterus. Endometrium and myometrium are the inner and the outer tissue linings of the uterus.

UTERUS FUNCTION

The uterus is the natural grooming bed for the fertilized egg. This egg called ovum gets implanted into the endometrium. The ovum draws its nourishment from the surrounding blood vessels linked to this lining. It is within the uterus that the ovum transforms into a fetus and then grows into the baby.
During pregnancy, the expanded ovum carrying uterus gets pushed into the abdomen. The pelvic portion provides the natural impetus in this process. At such times, the uterus mass weighs approximately a kilogram.

TISSUE UTERINE LININGS, PREGNANCY & MENSTRUATION

A normal woman enters her "fertile" stages every month. A girl attains this crucial womanhood stage once she attains puberty. The first major sign of puberty is menstruation. During this menstruation stage, the ovaries release a mature egg. The egg passes via the uterus. If at this time, the egg gets impregnated by a male sperm pregnancy happens. During this juncture, the tissue linings of the uterus grow thicker to provide insulation and a proper grooming environment to the fertilized egg.
However, if there is no fruitful meeting between the egg and the sperm, menstruation occurs. This is the time when the aforementioned uterine tissue linings start breaking up. The menstruation process refers to the flowing out of these uterine linings along with blood via the vagina.
