The cervical canal connects the interior of the vagina and the cavity of the body of uterus. The cervix is part of the female reproductive system.
The female reproductive tract is made of several connected internal sex organs—the vagina, uterus, and fallopian tubes—and is prone to infections. [1] The vagina allows for sexual intercourse, and is connected to the uterus at the cervix. The uterus (or womb) accommodates the embryo by developing the uterine lining.
The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the fallopian tubes. Each ovary contains hundreds of egg cells or ova (singular ovum). Approximately every 28 days, the pituitary gland releases a hormone that stimulates some of the ova to develop and grow. One ovum is released and it ...

Other proteins such as the HOX11 protein that is required for female fertility, is expressed in endometrial stroma cells throughout the menstrual cycle. Certain specific proteins such as the estrogen receptor are also expressed in other types of female tissue types, such as the cervix, fallopian tubes, ovaries and breast. [11]
One important type of parental care is the use of the mammary glands in the female breasts to nurse the baby. [4] The female reproductive system has two functions: The first is to produce egg cells, and the second is to protect and nourish the offspring until birth. The male reproductive system has one function, and it is to produce and deposit ...
The uterine cavity is the inside of the uterus. It is triangular in shape, the base (broadest part) being formed by the internal surface of the body of the uterus between the openings of the fallopian tubes, the apex by the internal orifice of the uterus through which the cavity of the body communicates with the canal of the cervix. The uterine ...
