The gastrointestinal or digestive tract, also referred to as the GI tract or the alimentary canal or the gut, is the system of organs within multicellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste.
The GI tract differs substantially from animal to animal. For instance, some animals have multi-chambered stomachs.

Diarrhea (American English) or diarrhoea (Commonwealth English) is a condition in which the sufferer has frequent and watery, chunky, or loose bowel movements (from the ancient Greek word διαρροή = leakage; lit. "to run through"). In the Third World, diarrhea is the most common cause of death among infants, killing more than 1.5 million per year.

This condition can be a symptom of injury, disease or foodborne illness and is usually accompanied by abdominal pain ...
In anatomy, the anus (from Latin ānus "ring, anus") is the external opening of the rectum. Closure is controlled by sphincter muscles. Feces are expelled from the body through the anus during the act of defecation, which is the primary function of the anus. Most animals — from simple worms to elephants and humans — have a tubular gut, with a mouth at one end and an anus at the other.
The anus is often considered a taboo part of the body, and is also known by a large number of slang terms, which are generally cons ...
A barium enema, also called a lower gastrointestinal series, is a medical procedure used to examine and dignose problems with the human large intestines. An X-ray examination of the large intestines, pictures are taken after rectal instillation of barium sulfate.
Barium enema - How the test is performed.
This test may be done in an office or a hospital radiology department. The patient lies on the X-ray table and a preliminary X-ray is taken. The patient is then asked to lie on the side while a well ...
In anatomy of the digestive system, the colon or large intestine or large bowel is the part of the intestine from the cecum to the rectum. Its primary purpose is to extract water from feces. In mammals, it consists of the cecum, ascending colon and approximately the first two-thirds of the transverse colon on the right (or proximal) side and the last third of the transverse colon to the splenic flexure, the descending colon, the sigmo ...
Gonorrhea (slang term "the clap") is among the most common curable sexually transmitted diseases in the world and is caused by the Gram-negative bacterium called Neisseria gonorrhoeae.
Infection with gonorrhea increases the risk of becoming infected with HIV (human immunodeficiency virus, the virus that causes AIDS). This is likely due to weakening of the mucosal surface secondary to the gonorrhea infection. Note, however, that this effect is by no means limited to gonorrhea and there is increased risk of HIV transmission with co-infect ...
Masturbation is the manual excitation of the sexual organs, most often to the point of orgasm. It can refer to excitation either by oneself or by another (see mutual masturbation), but commonly refers to such activities performed alone. It is part of a larger set of activities known as autoeroticism, which also includes the use of sex toys and non-genital stimulation. There are also masturbation machines used to simulate intercourse. Masturbation and sexual intercourse are the two most common sexual practices, but they are not mutuall ...
Syphilis (historically called lues) is a sexually transmitted disease (STD) that is caused by a spirochaete bacterium, Treponema pallidum. Syphilis has many alternate names, such as: Miss Siff, the Pox, and has been given many national attributions, e.g. the "French disease" or the "English disease".
The route of transmission for syphilis is almost invariably by sexual contact; however, there are examples of direct contact infections (see yaws) and of congenital syphili ...

Benign prostatic hyperplasia (BPH) also known as Benign prostatic hypertrophy or Benign enlargement of the prostate (BEP) refers to the increase in size of the prostate in middle-aged and elderly men. In BPH, the prostate grows larger and presses against the urethra and bladder, interfering with the normal flow of urine. It leads to symptoms of urinary hesitancy, frequent urination, increased risk of urinary tract infections and urinary retention. There is remarkably little correllation between BPH symptoms and th ...
Torture is any act by which severe torment, whether physical or psychological, is intentionally inflicted on a person as a means of intimidation, deterrent, revenge or punishment, or as a method for the extraction of information or confessions (i.e. "third-degree methods" of interrogation). Torture is often associated with terrible pain, severe suffering, and long-term trauma in its subjects.
Torture is almost universally considered to be an extreme violation of human rights, as stated by the Universal Declaration of Human Righ ...
Albert H. Fish (May 19, 1870 – January 16, 1936) was an American serial killer and cannibal. He was also known as the Moon Maniac, the Gray Man, and the Brooklyn Vampire.
Over the course of his criminal career, he murdered several children (some of whom he claimed to have eaten) and tortured others across the United States.

Butt plugs are sex toys that are designed to be inserted in the anus and rectum for sexual pleasure. In some ways, they are similar to a dildo, but they tend to be shorter, and to have a flared end to prevent the device from being lost inside the anus.
Butt plugs are popular with and can be pleasurable for both men and women, both heterosexual and homosexual.
Unlike the vagina, which is closed off by the cervix, the rectum leads to the sigmoid colon. Objects which are inserted into the rectum can therefore potentially travel up into the bowel: the f ...
Colonoscopy is the minimally invasive endoscopic examination of the large colon and the distal part of the small bowel with a fiber optic camera on a flexible tube passed through the anus. It may provide a visual diagnosis (e.g. ulceration, polyps) and grants the opportunity for biopsy of suspected lesions. Virtual colonoscopy, which uses 3D imagery reconstructed from computed tomography (CAT) scans, is also possible, as a totally non-invasive medical test, although it is not standard and still under investigation. Colonoscopy is simi ...
Anal sex or anal intercourse is a commonly practiced form of human sexual behaviour in some cultures. It involves the anus and possibly the rectum, especially, but not limited to, the insertion of the erect penis into the rectum through the anus.
The use of sex toys and other activities involving the anus and rectum may be considered anal sex as well. Anal sex can be pleasurable for both the insertive partner and the receptive partner, as the anus contains many of the ...
A cream is a topical preparation usually for application to the skin. Creams for application to mucus membranes such as those of the rectum or vagina are also used. Creams may be considered pharmaceutical products as even cosmetic creams are based on techniques developed by pharmacy and unmedicated creams are highly used in a variety of skin conditions (dermatoses).
Creams are semi-solid emulsions, that is mixtures of oil and water. They are divided into two types: oil-in-water (O/W) creams which are composed of s ...
In the anatomy of mammals, the urinary bladder is the organ that collects urine excreted by the kidneys prior to disposal by urination. Urine enters the bladder via the ureters and exits via the urethra.
Urinary bladder - Anatomy.
The urinary bladder is a hollow, muscular and distensible organ that sits on the pelvic floor (superior to the prostate in males). On its anterior border lies the pubic symphysis and, on its posterior border, the vagina (in females) and rectum (in males). The urinary bladd ...
Colorectal cancer, also called colon cancer or bowel cancer, includes cancerous growths in the colon, rectum and appendix. It is the third most common form of cancer and the second leading cause of death among cancers in the Western world. Many colorectal cancers are thought to arise from adenomatous polyps in the colon. These mushroom-like growths are usually benign, but some may develop into cancer over time. The majority of the time, the diagnosis of localized colon cancer is through colonoscopy. Therapy is usually th ...

Ulcerative colitis is an inflammatory disease of the bowel that usually affects the distal end of the large intestine and rectum. It has no known cause, although there is a genetic component to susceptibility.
Ulcerative colitis - Features.
Chronic diarrhoea (sometimes bloody). Other symptoms may include abdominal pain and discomfort, bloating, and nausea.
No infective cause of diarrhea found.
Inflammatory changes are most often confined to the left side and distal parts of the large ...
