Diagram of the uterus and part of the vagina. The cervix is the lower part of the uterus situated between the external os (external orifice) and internal os (internal orifice). 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.
A small proportion of the sperm pass through the cervix into the uterus and then into the fallopian tubes for fertilization of the ovum. Only one sperm is required to fertilize the ovum. Upon successful fertilization, the fertilized ovum, or zygote, travels out of the fallopian tube and into the uterus, where it implants in the uterine wall.
When the fetus has developed enough to survive outside the uterus, the cervix dilates, and contractions of the uterus propel it through the birth canal (the vagina), where it becomes a newborn. The breasts are not part of the reproductive system, but mammary glands were essential to nourishing infants until the modern advent of infant formula.

The uterus can be divided anatomically into four regions: the fundus – the uppermost rounded portion of the uterus above the openings of the fallopian tubes, [4] the body, the cervix, and the cervical canal. The cervix protrudes into the vagina. The uterus is held in position within the pelvis by ligaments, which are part of the endopelvic ...
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 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 passes through the ...
Diagram showing parts of the stomach. The human stomach can be divided into four sections, beginning at the cardia followed by the fundus, the body and the pylorus. [7] [8] The gastric cardia is where the contents of the esophagus empty from the gastroesophageal sphincter into the cardiac orifice, the opening into the gastric cardia.
