Relationships Between The Reproductive System and Other Systems

Relationship Between the Reproductive System and the Endocrine System

These two system share a common organ: the ovaries. The endocrine system sends hormonal messages to the reproductive system (just like it does to any other system). Once the hormone is secreted, traveling from the endocrine gland through the bloodstream to target the cells designed to receive its message. The endocrine system sends information to the reproductive system regard when to release the eggs, with which, starting the menstruation cycle.

Relationship Between the Reproductive System and the Nervous System

Both of these systems are greatly affected by the other. Reproductive hormones affect brain development. They also sway with the sexual behavior of a human being. On the other hand, the brain controls mating behavior, which is a key point in the process of reproduction.

Reproductive System Overview

The female reproductive system. The system that is crucial to life, life depends on it, without it the human race would die out. It fulfils on of the seven basic life processes. I think it has been stated just how important it is. It is a system in which the organs that make it up, work together for the purpose of reproduction.

Ovaries

The two oval shaped organs that lie to the upper right and left of the uterus are called the ovaries. The ovaries produce, store, and release the eggs into the fallopian tubes in the process called ovulation. Each ovary is about one and a half to two inches in a grown woman. They are part of the endocrine system and they produce hormones such as estrogen and progestrogen. Estrogen is responsible for the secondary sex characteristics in female puberty. Progestrogen functions with estrogen and prepares the endometrium for pregnancy.

Uterus

The uterus is connected with the vagina at the cervix. It is also known as the womb. The uterus is shaped like an upside down pear. It has thick lining and muscular walls and even has some of the strongest muscles in the body. The muscles expand and contract to make room for the growing fetus, if the woman is pregnant, and then push out during labor. When the woman isn’t pregnant, her uterus is only 3 inches long and 2 inches wide. Two uteruses usually form in the female body, and in placental mammals they may partially or completely fuse into a single uterus depending on the species.

Urethra

The urethra is the canal that carries urine from the bladder to the outside of the body. It is about 2-5 inches long and it contains 3 coats. The three coats are the muscular, the erectile, and the mucous, the muscular layer being a continuation of that of the bladder. The area on top of the urethra and on both sides of it is thought to be sexually sensitive. It is sometimes called the VAKI U-spot or urethral erogenous zone. It exits between the clitoris and the vagina. It extends from the internal to the external urethral orifice. You can also get cancer in the urethra. It is named so: Urethral Cancer.

Fallopian Tubes

The fallopian tubes, also called the oviduct or uterine tubes, a part of the female reproductive system, through which the ovaries pass to the uterus. Women have two fallopian tubes. This is usually where the male sperm fertilizes the egg. Each tube measures 4 inches or 10 centimeters in length. Two types of cells line this organ. Ciliated cells have cilia on their surface to help the egg into and through the fallopian tubes. As the name suggests, secretory cells produce secretions that nourish the egg.

Vagina

The vagina, a tube-shaped canal, is a crucial part of the female reproductive system. It is located between the bladder and the urethra or the urinary canal. The vagina measures about 4 inches or 10 centimeters. This organ stretches from the cervix (lower part of the uterus) to an opening between the legs.

The lining of the organ, the mucous membrane has numerous ridges and folds running across it. The mucous membrane contains numerous nerve endings. “The areas near the vaginal opening and around the clitoris, a small knob of tissue in front of the urethra, are especially sensitive to stimulation.” Vaginal internal surfaces are lubricated be secretions from glands in the cervix. Normally, the walls of the organ are collapsed in such a manner that the walls touch each other. In females, who have not had sexual intercourse, the opening of the vagina might be covered by the hymen (a thin membrane). Breaking of this membrane is not dangerous but may cause pain.
