There are three clinically significant concentric zones of prostatic glandular tissue about the urethra. The cervix separates the uterus from the vagina or birth canal, where the sperm are deposited see diagram Many girls also experience abdominal cramps during the first few days of their periods.
Just before birth the mother often becomes restless, lying down and getting up frequently. The female reproductive system is complex as compared to the male reproductive system.
Most other animals restrict reproduction to one or two seasons in the year-seasonal breeders see diagram The body of the penis, sometimes referred to as the shaft, is cylindrical in shape when flaccid but when erect is somewhat triangular in cross sectionwith the angles rounded.
It is a Reproductive system in nutrients and contains protective antibodies from the mother. It can then be diluted, stored and used to inseminate females. The liquid produced by the seminal vesicles contains proteins and mucus and has an alkaline pH to help sperm survive in the acidic environment of the vagina.
The corpus can easily expand to hold a developing baby. Ejaculatory Duct The ductus deferens passes through the prostate and joins with the urethra at a structure known as the ejaculatory duct. The urethra enters it on the flattened deep aspect that lies against the perineal membrane, traverses its substances, and continues into the corpus spongiosum.
The male reproductive system consists of a pair of testes that produce sperm or spermatozoaducts that transport the sperm to the penis and glands that add secretions to the sperm to make semen. The ovary consists of an inner region medulla and an outer region cortex containing egg cells or ova.
There is some evidence that the ductules and the first portion of the duct of the epididymis remove excess fluid and extraneous debris from the testicular secretions entering these tubes. The ductules from the testis have a thin muscular coat and a lining that consists of alternating groups of high columnar cells with cilia hairlike projections and low cells lacking cilia.
Epispadiasan opening in the upper dorsal side of the penis, is considerably less common than hypospadias. The accessory glands, including the seminal vesicles and the prostate gland, provide fluids that lubricate the duct system and nourish the sperm.
A cow mounts other cows bullingbellows, is restless and has a discharge from the vulva. Genetic and congenital abnormalities In the male Congenital anomalies of the prostate gland and seminal vesicles are rare; they consist of absence, hypoplasia underdevelopmentor the presence of fluid- or semisolid-filled sacs, called cysts.
There are two fallopian tubes, each attached to a side of the uterus. This process is called implantation. The prostate gland contributes additional fluid to the ejaculate.
Conceptionthe fertilization of an egg by a sperm, normally occurs in the fallopian tubes. It occurs when cells in the testicle divide abnormally and form a tumor. A female's internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries.
The fluid is thin, milky, and slightly acidic. During this phase, the following events occur: The skin of the penis is loose and elastic to accommodate changes in penis size during an erection.
These chambers are made up of special, sponge-like tissue. It is brought about by the contraction of the epididymis, vas deferens, prostate gland and urethra.Reproductive System.

Its function is to enable reproduction of the species. Sexual maturation is the process that this system undergoes in order to carry out its role in the process of pregnancy and birth.
Internal reproductive organs. The reproductive system is a collection of internal and external organs — in both males and females — that work together for the purpose of procreating, according to the Cleveland Clinic.

Testis means “witness” in Latin. As the testis witnesses to manhood, you may witness to the truth at trial, proclaim your favorite brand of corn flakes or witness to your final wishes in your will.Download
