Organs Organs In animals, the brain, or encephalon ( Greek for "in the head"), acts as the control center of the central nervous system. In most animals, the brain is located in the head close to the primary sensory apparatus and the mouth. While all vertebrate nervous systems have a brain, invertebrate nervous systems may have either a centralized brain or collections of individual ganglia. The brain is an extremely complex organ; for example, the human brain is a collection of 100 billion neurons, each linked with up to 25,000 others ** . This huge number of interconnecting neurons—often referred to as a neural ensemble—is what allows the brain to conduct such complex processes. ...more on Wikipedia about "Brain"
The clitoris (plural: clitorides) is a sexual organ in the body of female mammals. The visible knob-like portion is located near the anterior junction of the labia minora, above the opening of the vagina. The clitoris has no urethra and functions solely to induce sexual pleasure. The only known exception to this is in the Spotted Hyena, where the urogenital system is modified so that the female urinates, mates and gives birth via an enlarged, erectile clitoris. ...more on Wikipedia about "Clitoris"
The gas bladder (also fish maw, less accurately swim bladder or air bladder) is an internal organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at the current water depth, ascend, or descend without having to waste energy in swimming. ...more on Wikipedia about "Gas bladder"
In aquatic organisms, gills are a respiratory organ for the extraction of oxygen from water and for the excretion of carbon dioxide. ...more on Wikipedia about "Gill"
The heart ( Latin cor) is a hollow, muscular organ that pumps blood through the blood vessels by repeated, rhythmic contractions. The term cardiac means "related to the heart", from the Greek kardia (καρδια) for "heart". ...more on Wikipedia about "Heart"
The kidneys are bean-shaped excretory organs in vertebrates. Part of the urinary system, the kidneys filter wastes (especially urea) from the blood and excrete them, along with water, as urine. The medical field that studies the kidneys and diseases affecting the kidney is called nephrology, from the Greek name for the kidney; the adjective meaning "kidney-related" is renal, from the Latin. ...more on Wikipedia about "Kidney"
The liver is an organ in vertebrates, including humans. It plays a major role in metabolism and has a number of functions in the body including drug detoxification, glycogen storage, and plasma protein synthesis. It also produces bile, which is important for digestion. Medical terms related to the liver often start in hepato- or hepatic from the Greek word for liver, hepar. ...more on Wikipedia about "Liver"

In biology, an organ ( Latin: organum, "instrument, tool") is a group of tissues, which perform a specific function or group of functions. Common animal organs include the heart, lungs, brain, eye, stomach, spleen, pancreas, kidneys, liver, intestines, skin, uterus, bladder, bone, etc. A group of related organs is an organ system. ...more on Wikipedia about "Organ (anatomy)"

The penis (plural penises or penes) or phallus is an external male sexual organ. The penis is the male reproductive organ and for mammals additionally serves as the external male organ of urination. ...more on Wikipedia about "Penis"
A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores. Underground storage organs and the plants that bear them are sometimes called geophytes. ...more on Wikipedia about "Storage organ"
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. ...more on Wikipedia about "Urinary bladder"
The uterus or womb is the major female reproductive organ of most mammals, including humans. One end, the cervix, opens into the vagina; the other is connected on both sides to the fallopian tubes. In mammals, the four main forms in which it is found are: bipartite, as in cows; bicornuate, as in pigs; simplex, as with the pear-shaped one found in humans and horses; and duplex, found in rabbits. ...more on Wikipedia about "Uterus"
In biology, a clasper or valva (plural valvae) is a body part of male insects that is used to hold the female during copulation. ...more on Wikipedia about "Valva"
In human anatomy, the vermiform appendix (or appendix, pl. appendixes) is a blind ended tube connected to the cecum. It develops embryologically from the cecum. In adults, the appendix averages 10 cm in length but can range from 2-20 cm. The diameter of the appendix is usually less than 7-8 mm. While the base of the appendix is at a fairly constant location, the location of the tip of the appendix can vary from being retrocaecal to being in the pelvis to being extraperitoneal. In most people, the appendix is located at the lower right quadrant of the abdomen. In people with situs inversus, the appendix may be located in the lower left side. ...more on Wikipedia about "Vermiform appendix"
