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.

Cervix
Mucosa – unlike the rest of the uterus, it is not lost during menstruation.
Endocervix – forms the wall of the cervical canal.
Simple Columnar Epithelium – mostly mucus-secreting cells continuous with the lining of the body of the uterus.
Cervical Glands – branched glands of mucus-secreting cells located in the lamina propria.
Ectocervix (or exocervix) – part of the cervix that protrudes in the vagina (portio vaginalis) and contains the opening of the uterus (external os).
Stratified Squamous Non-Keratinized Epithelium – continuous with the lining of the vagina.
Estrogen promotes the storage of glycogen in the middle and upper layers of the epithelium.
Cervical Glands – relatively few glands are found and are similar to those in the endocervix.
Transformation Zone – abrupt junction between the mucus-secreting columnar epithelium of the endocervix and the squamous epithelium of the ectocervix.
Nabothian Cysts – develop as stratified squamous epithelium grows over mucus-secreting simple columnar epithelium and entraps large amounts of mucus.
Cervical Wall – composed of dense connective tissue rich in both collagen and elastic fibers. Unlike the rest of the uterus, it contains little smooth muscle.
