The corpus uteri, or body of the uterus, is the main part of the uterus located above the cervix, playing a crucial role in reproductive health by housing and nurturing the developing fetus during pregnancy. It is composed of three layers: the endometrium, myometrium, and perimetrium, each serving specific functions in menstruation and gestation.

Corpus Uteri

The body of the uterus, also known as the corpus uteri, is the major portion of the uterus and plays a crucial role in reproductive functions, including housing and nourishing a fertilized egg until it develops into a fetus. It is lined with the endometrium, which thickens during the menstrual cycle in preparation for potential implantation and sheds during menstruation if fertilization does not occur.

Body Of The Uterus

Main part of the uterus

The cervix is a cylindrical-shaped neck of tissue that connects the vagina and uterus, playing a crucial role in reproductive health by acting as a barrier to protect the uterus from pathogens and facilitating the passage of sperm. It also undergoes significant changes during menstruation and childbirth, making it a vital focus in gynecological health and cancer screening.

Cervix

Reproductive health encompasses a state of complete physical, mental, and social well-being in all matters relating to the reproductive system at all stages of life. It implies that individuals have a safe, satisfying, and informed approach to sexual and reproductive life, with the capability to reproduce and the freedom to decide if, when, and how often to do so.

Reproductive Health

Developing fetus

Pregnancy is the biological process in which a fertilized egg develops into a fetus within a woman's uterus, typically lasting about 40 weeks from the last menstrual period to childbirth. It involves complex physiological changes and requires careful medical monitoring to ensure the health of both the mother and the developing baby.

Pregnancy

Three layers

The endometrium is the inner lining of the uterus, playing a crucial role in the menstrual cycle and pregnancy. It thickens in response to hormonal changes to prepare for potential implantation of an embryo, and sheds during menstruation if implantation does not occur.

Endometrium

The myometrium is the middle layer of the uterine wall, composed mainly of smooth muscle tissue, and plays a crucial role in uterine contractions during menstruation and childbirth. Its structure and function are essential for reproductive health, influencing processes such as labor and delivery, as well as conditions like uterine fibroids and myometrial hyperplasia.

Myometrium

The perimetrium is the outermost layer of the uterus, composed of a thin layer of epithelial cells and connective tissue that provides structural support and protection. It is part of the uterine wall's three-layer structure, playing a crucial role in maintaining the integrity and function of the uterus in reproductive health.

Perimetrium

Specific Functions

Menstruation is a natural biological process in which the uterine lining is shed, resulting in bleeding through the vagina, occurring typically on a monthly cycle in individuals with female reproductive systems. It is a critical component of the menstrual cycle, which prepares the body for potential pregnancy and involves hormonal changes, physical symptoms, and emotional fluctuations.

Menstruation

Gestation is the period during which an embryo or fetus develops inside a mother's womb, culminating in birth. It varies significantly across species, with humans typically experiencing a gestation period of approximately nine months from conception to delivery.
