Vagina – It Is an lactic, muscular tube that connects the cervix of the uterus to the exterior of the body. It serves as the birth canal by stretching to allow delivery of the fetus during childbirth. 2. Uterus – It is a hollow, muscular, pear-shaped organ located posterior and superior to the urinary bladder. Connected to the two fallopian tubes on its superior end and to the vagina (via the cervix) on its inferior end. 3. Fallopian Tubes – They are a pair of muscular tubes that extend from the left and right superior corners of the uterus to the edge of the ovaries. 4.
Ovaries – They are a pair of small glands about the size and shape of almonds. Ova (commonly called “eggs”). II. Male Reproductive System Here is an overview of the male reproductive system: The principal parts of the reproductive system include: 1. Testis (Testes) – They are the male gonads responsible for the production of sperm and testosterone. The inside of the testes is divided into small compartments known as lobules. Each lobule contains a section of coniferous tubule lined with epithelial cells. 2. Epidemics – It is a sperm storage area that wraps around the superior and exterior edge of the testes. . Vass Deferent – Also known as the duct defense, is a muscular tube that carries sperm superiorly from the epidemics into the abdominal cavity to the ejaculatory duct. 4. Prostate – An exocrine gland that produces a large portion of the fluid that makes up semen. This fluid is milky white in color and contains enzymes, proteins, and other chemicals to support and protect sperm during ejaculation. 5. Ejaculatory Duct – This is where the Vass deferent passes through the prostate and joins with the urethra. It contains the ducts from the seminal vesicles as well.
During ejaculation, the duct opens and expels sperm and the secretions from the seminal vesicles into the urethra. About once every 8 days in a sexually mature female. It starts at the moment a single sperm unites with an ovum in the oviduct of the fallopian tube. The union forms a new cell called a zygote. The approximate duration of pregnancy called gestation period is 260 days. This is equivalent to 9 months and is divided into three periods called a trimester.
