Anal Fisting
Fisting, handballing, fist-fucking, brachiovaginal, or brachioproctic insertion is a Human sexual activity, sexual activity that involves inserting a hand into the vagina or rectum. Once insertion is complete, the fingers are either clenched into a fist or kept straight. Fisting may be performed without a partner, but it is most often a partnered activity. History Fisting's emergence as a popular sexual practice is commonly attributed to gay male culture and it may not have existed until the twentieth century. Robert Morgan Lawrence, a sex educator, however, believes the practice dates back thousands of years. The most famous fisting club in the world was the Catacombs (fisting club), Catacombs, located in San Francisco, which operated during the 1970s and 1980s.; reprinted in The Handball Express was another such club. Crisco was commonly used as a lubricant, before more specialized personal lubricants became available. In the 1980s, it was assumed that unprotected fisting鈥 ...

Leather Subculture
Leather subculture denotes practices and styles of dress organized around sexual activities that involve leather garments, such as leather jackets, vests, boots, chaps, harnesses, or other items. Wearing leather garments is one way that participants in this culture self-consciously distinguish themselves from mainstream sexual cultures. Many participants associate leather culture with BDSM (Bondage/Discipline, Dominance/Submission, Sado/Masochism, also called "SM" or "S&M") practices and its many subcultures. For some, black leather clothing is an erotic fashion that expresses heightened masculinity or the appropriation of sexual power; love of motorcycles, motorcycle clubs and independence; and/or engagement in sexual kink or leather fetishism."Elegy for the Valley of Kings," by Gayle Rubin, in ''In Changing Times: Gay Men and Lesbians Encounter HIV/AIDS,'' ed.

Colorectal Perforation
Gastrointestinal perforation, also known as ruptured bowel, is a hole in the wall of part of the gastrointestinal tract. The gastrointestinal tract includes the esophagus, stomach, small intestine, and large intestine. Symptoms include severe abdominal pain and tenderness. When the hole is in the stomach or early part of the small intestine, the onset of pain is typically sudden while with a hole in the large intestine onset may be more gradual. The pain is usually constant in nature. Sepsis, with an increased heart rate, increased breathing rate, fever, and confusion may occur. The cause can include trauma such as from a knife wound, eating a sharp object, or a medical procedure such as colonoscopy, bowel obstruction such as from a volvulus, colon cancer, or diverticulitis, stomach ulcers, ischemic bowel, and a number of infections including '' C. difficile''. A hole allows intestinal contents to enter the abdominal cavity. The entry of bacteria results in a condition known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Embolism
An air embolism, also known as a gas embolism, is a blood vessel blockage caused by one or more bubbles of air or other gas in the circulatory system. Air can be introduced into the circulation during surgical procedures, lung over-expansion injury, decompression, and a few other causes. Air embolisms may also occur in the xylem of vascular plants, especially when suffering from water stress. Divers can develop ''arterial'' gas embolisms as a consequence of lung over-expansion injuries. Breathing gas introduced into the venous system of the lungs due to pulmonary barotrauma will not be trapped in the alveolar capillaries, and will consequently be circulated to the rest of the body through the systemic arteries, with a high risk of embolism. Inert gas bubbles arising from decompression are generally formed in the ''venous'' side of the systemic circulation, where inert gas concentrations are highest, these bubbles are generally trapped in the capillaries of the lungs where the ...

Colon (anatomy)
The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in tetrapods. Water is absorbed here and the remaining waste material is stored in the rectum as feces before being removed by defecation. The colon is the longest portion of the large intestine, and the terms are often used interchangeably but most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal. Some other sources exclude the anal canal. In humans, the large intestine begins in the right iliac region of the pelvis, just at or below the waist, where it is joined to the end of the small intestine at the cecum, via the ileocecal valve. It then continues as the colon ascending the abdomen, across the width of the abdominal cavity as the transverse colon, and then descending to the rectum and its endpoint at the anal canal. Overall, in humans, the large intestine is about long, which is about one-fifth o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perineum
The perineum in humans is the space between the anus and scrotum in the male, or between the anus and the vulva in the female. The perineum is the region of the body between the pubic symphysis (pubic arch) and the coccyx (tail bone), including the perineal body and surrounding structures. There is some variability in how the boundaries are defined. The perineal raphe is visible and pronounced to varying degrees. The perineum is an erogenous zone. The word perineum entered English from late Latin via Greek 蟺蔚蟻委谓伪喂慰蟼 ~ 蟺蔚蟻委谓蔚慰蟼 ''perinaios, perineos'', itself from 蟺蔚蟻委谓蔚慰蟼, 蟺蔚蟻委谓蔚慰喂 'male genitals' and earlier 蟺蔚蟻委蟼 ''per铆s'' 'penis' through influence from 蟺畏蟻委蟼 ''p膿r铆s'' 'scrotum'. The term was originally understood as a purely male body-part with the perineal raphe seen as a continuation of the scrotal septum since masculinization causes the development of a large anogenital distance in men, in comparison to the corresponding lack ...

Organ Perforation
Organ perforation is a complete penetration of the wall of a hollow organ in the body, such as the gastrointestinal tract in the case of gastrointestinal perforation. It mainly refers to accidental or pathologic perforation, rather than intentional penetration during surgery. It can lead to peritonitis if untreated. Types include gastrointestinal perforation and uterine perforation Uterine perforation is a potential complication of any intrauterine procedure. It may be associated with injury to surrounding blood vessels or viscera such as the bladder or intestine. If not diagnosed at the time of the procedure it can occasiona ....

Laceration
A wound is a rapid onset of injury that involves lacerated or punctured skin (an ''open'' wound), or a contusion (a ''closed'' wound) from blunt force trauma or compression. In pathology, a ''wound'' is an acute injury that damages the epidermis of the skin. To heal a wound, the body undertakes a series of actions collectively known as the wound healing process. Classification According to level of contamination, a wound can be classified as: * Clean wound 鈥 made under sterile conditions where there are no organisms present, and the skin is likely to heal without complications. * Contaminated wound 鈥 usually resulting from accidental injury; there are pathogenic organisms and foreign bodies in the wound. * Infected wound 鈥 the wound has pathogenic organisms present and multiplying, exhibiting clinical signs of infection (yellow appearance, soreness, redness, oozing pus). * Colonized wound 鈥 a chronic situation, containing pathogenic organisms, difficult to heal (e.g. b ...

Thrust
Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system. The force applied on a surface in a direction perpendicular or normal to the surface is also called thrust. Force, and thus thrust, is measured using the International System of Units (SI) in newtons (symbol: N), and represents the amount needed to accelerate 1 kilogram of mass at the rate of 1 meter per second per second. In mechanical engineering, force orthogonal to the main load (such as in parallel helical gears) is referred to as static thrust. Examples A fixed-wing aircraft propulsion system generates forward thrust when air is pushed in the direction opposite to flight. This can be done by different means such as the spinning blades of a propeller, the propelling jet of a jet engine, or by ejecting hot gases from a rocket ...

Anus
The anus (Latin, 'ring' or 'circle') is an opening at the opposite end of an animal's digestive tract from the mouth. Its function is to control the expulsion of feces, the residual semi-solid waste that remains after food digestion, which, depending on the type of animal, includes: matter which the animal cannot digest, such as bones; Summary at food material after the nutrients have been extracted, for example cellulose or lignin; ingested matter which would be toxic if it remained in the digestive tract; and dead or excess gut bacteria and other endosymbionts. Amphibians, reptiles, and birds use the same orifice (known as the cloaca) for excreting liquid and solid wastes, for copulation and egg-laying. Monotreme mammals also have a cloaca, which is thought to be a feature inherited from the earliest amniotes via the therapsids. Marsupials have a single orifice for excreting both solids and liquids and, in females, a separate vagina for reproduction. Female placental mamm ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections 鈥 the upper and lower mandibles 鈥 are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened bills o ...
