The ampulla is the second portion of the uterine tube. It is an intermediate dilated portion, which curves over the ovary.

It is the most common site of human fertilization.

For ovary as part of plants see ovary (plants)
An ovary is an egg-producing reproductive organ found in female organisms. They are usually purple. It is often found in pairs as part of the vertebrate female reproductive system.

The Fallopian tubes, also known as oviducts, uterine tubes, and salpinges (singular salpinx) are two very fine tubes leading from the ovaries of female mammals into the uterus.

The ostium of the Fallopian tube is the opening in the infundibulum of uterine tube into the abdominal cavity. In ovulation, the oocyte enters the Fallopian tube through this opening.

It is surrounded by fimbriae, which help in the collection of the oocyte.

The third part of the uterine tube is the the infundibulum. It terminates with the ostium of Fallopian tube, surrounded by fimbriae, one of which, the ovarian fimbria is attached to the ovary.
..... Click the link for more information.
In the female reproductive system, the fimbria (plural, fimbriae) is a fringe of tissue around the ostium of the Fallopian tube, in the direction of the ovary.

An ovary is not directly connected to its adjacent Fallopian tube.

The first part of the uterine tube is the isthmus tubae uterinae. It is the medial third, and it is constricted.

Sexual reproduction.


The human female reproductive system contains two main parts: the vagina and uterus, which act as the receptacle for the male's sperm, and the ovaries, which produce the female's ova.

The reproductive system is the ensembles and interactions of organs and/or substances within an organism that strictly pertain to reproduction. As an example, this would include in the case of female mammals, the hormone estrogen, ova, and the uterus and the vagina, and the breasts.

Oogenesis or rarely oögenesis is the creation of an ovum (egg cell). It is the female process of gametogenesis. It involves the various stages of immature ova.

Oogenesis in mammals

In mammals, oogenesis occurs in the ovarian follicle of the ovary.

The surface of the ovary is covered by a layer of columnar cells which constitutes the germinal epithelium of Waldeyer. (Some sources consider it simple cuboidal.[1]

On the surface of the ovary this tissue is much condensed, and forms a layer, the tunica albuginea, composed of short connective-tissue fibers, with fusiform cells between them.

The stroma of the ovary is a peculiar soft tissue, abundantly supplied with bloodvessels, consisting for the most part of spindle-shaped cells with a small amount of ordinary connective tissue.

The medulla of ovary (or Zona vasculosa of Waldeyer) is a highly vascular stroma in the center of the ovary.

This stroma forms the tissue of the hilum by which the ovary is attached, and through which the bloodvessels enter: it does not contain any ovarian follicles.

corpus albicans (Latin for "white body" ) is the regressed form of the corpus luteum. As the corpus luteum is being broken down by macrophages, fibroblasts lay down type I collagen, forming the corpus albicans. This process is called "luteolysis".
