Question

define uterus
and state its function​

Answer 1

Functions of the uterus. Functions of the uterus include nurturing the fertilized ovum that develops into the fetus and holding it till the baby is mature enough for birth. The ferlized ovum gets implanted into the endometrium and derives nourishment from blood vessels which develop exclusively for this purpose.

Answer 2

The uterus is an organ of the female reproductive system. It’s shaped like an upside-down pear and has thick walls. The uterus’s main function is to house and nourish a fetus until it’s ready for birth.

Fundus
The fundus is the upper part of the uterus. It’s broad and curved. The fallopian tubes attach to the uterus just below the fundus.

Corpus
The corpus is the main body of the uterus. It’s very muscular and can stretch to accommodate a developing fetus. During labor, the muscular walls of the corpus contract to help push the baby through the cervix and vagina.

The corpus is lined by a mucus membrane called the endometrium. This membrane responds to reproductive hormones by changing its thickness during each menstrual cycle. If an egg is fertilized, it attaches to the endometrium. If no fertilization occurs, the endometrium sheds its outer layer of cells, which are released during menstruation.

Isthmus
The portion of the uterus between the corpus and the cervix is called the isthmus. This is where the walls of the uterus begin to narrow toward the cervix.

Cervix
The cervix is the lowest part of the uterus. It’s lined with a smooth mucous membrane and connects the uterus to the vagina. Glands in the cervical lining usually produce a thick mucus. However, during ovulation, this becomes thinner to allow sperm to easily pass into the uterus.

The cervix has three main parts:

Endocervix. This is the inner part of the cervix that leads to the uterus.
Cervical canal. The cervical canal links the uterus to the vagina.
Exocervix. The exocervix is the outer part of the cervix that protrudes into the vagina.
During childbirth, the cervix dilates (widens) to allow the baby to pass through the birth canal.
