The reproductive system ensures the survival of the species. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for the survival of the individual. An individual may live a long, healthy, and happy life without producing offspring, but if the species is to continue, at least some individuals must produce offspring.

A stratified squamous epithelium with a minor degree of keratinization lines the vagina. A thick layer of dense connective tissue, similar to that found in the skin's dermis, lies beneath the epithelium. Following this is a layer of loose connective tissue with numerous blood vessels and nerves. Because they produce and store glycogen, vaginal…[Read more]

The cervix is located at the bottom of the uterus and protects it from bacterial infiltration. It is the location of a critical epithelial transition. The lining of the upper cervix (endocervix) is a simple columnar epithelium that contains mucous-secreting cells. The lower cervix, on the other hand, is lined by a stratified squamous epithelium.…[Read more]

At the end of menstrual flow, the uterine cycle enters the early proliferative phase. The uterine glands are sparse and small during this phase, and the epithelial cells develop microvilli and cilia under the influence of estrogen. The stratum functionalis thickens in the late proliferative phase, and the glands become more coiled and densely…[Read more]

The uterus is divided into layers, each with its own structural and functional characteristics. The mucosal layer, or endometrium, the muscularis layer, or myometrium, and the serosal layer, or perimetrium are the most basic classifications of these layers. The endometrium is composed of two layers: the stratum functionalis and the stratum…[Read more]

The oviduct epithelium is made up of two types of cells. The ciliated cells take precedence and help to move the ovum away from the ovary and toward the uterus. Non-ciliated secretory cells, also known as peg cells, secrete a secretion that lubricates the tube while also feeding and protecting the traveling ovum.
-
-
-
The oviduct is made up of several segments, including the infundibulum, which contains fimbriae and is located near the ovary, the ampulla, the isthmus, and the pars interstitialis. The first two of these regions have a distinct appearance dominated by an elaborate mucosa thrown into numerous branched folds and surrounded by a relatively thin…[Read more]

At any stage of development, follicle degeneration (atresia) can occur. The granulosa cells die, and the oocyte degenerates as a result. The basement membrane that separates the oocyte from the granulosa cells frequently thickens to form the glassy membrane. The granulosa cells are replaced by fibrous material.

-
If fertilization does not occur, the corpus luteum involutes to form the fibrous tissue-filled corpus albicans. The corpus luteum's secretory cells degenerate and are phagocytosed by macrophages.
-
-
-
The granulosa lutein cells have a steroid-producing cell appearance, with pale cytoplasm indicating the presence of lipid droplets. Theca lutein cells are smaller and darker in color. If fertilization and implantation occur, hCG will keep the corpus luteum active as the corpus luteum of pregnancy.
