Human anatomy
"Physiologies" redirects here. For other uses, see Physiology. The study of the human body involves anatomy and physiology. Structure[edit] The human body has several body cavities the largest of which is the abdominopelvic cavity. Composition[edit] The main elements that compose the human body are shown from most abundant to least abundant. The average adult body contains between 5 and 5½ litres of blood and approximately 10 litres of interstitial fluid. The composition of the human body can be referred to in terms of its water content, elements content, tissue types or material types. The vast majority of cells in the human body are not human at all; rather they are of bacteria, archaea, and methanogens such as Methanobrevibacter smithii. The proportions of the elements of the body can be referred to in terms of the main elements, minor ones and trace elements.

Muscular System Anatomy, Diagram & Function Without muscle, humans could not live. The primary job of muscle is to move the bones of the skeleton, but muscles also enable the heart to beat and constitute the walls of other important hollow organs. There are three types of muscle tissue: Skeletal muscle: This type of muscle creates movement in the body. Muscle movement happens when neurological signals produce electrical changes in muscle cells. Muscle pain is a common issue that can signal numerous problems, even if it’s something as simple as overuse. Muscle pain Sprains and strains Bruising Cramping Myopathy Muscular dystrophy Parkinson’s disease Fibromyalgia Multiple sclerosis Proper nutrition and exercise is important to keeping all muscles healthy, whether they are cardiac, smooth, or skeletal.

Waivers (NHL) Waivers is a National Hockey League (NHL) labor management procedure by which an NHL team makes a professional ice hockey player’s contract and rights available to all other NHL teams. The term "waivers" refers to a concept wherein other NHL teams 'waive' any claim to a player designated for assignment in the AHL or designated for release. The process is typically referred to as 'being placed on waivers.' In the NHL, each player signs what is, or is a variation of, a standard NHL player's contract. After a player has been designated for assignment, the other 29 NHL teams can put in a claim or waive their claim for that player. When a player clears waivers and is sent down and then is called up again, he does not have to clear waivers to be sent down again unless he has played ten games or has been "up" for 30 days.[5] The 2005 NHL-NHLPA collective bargaining agreement introduced re-entry waivers. The 2013 collective bargaining agreement eliminated re-entry waivers.

Wings of Change - Formation to Success Anatomy of the Human Heart - Texas Heart Institute Heart Information Center Click here for non-Flash version of this illustration of anatomy of the heart. Your heart is located between your lungs in the middle of your chest, behind and slightly to the left of your breastbone (sternum). A double-layered membrane called the pericardium surrounds your heart like a sac. The outer layer of the pericardium surrounds the roots of your heart's major blood vessels and is attached by ligaments to your spinal column, diaphragm, and other parts of your body. The inner layer of the pericardium is attached to the heart muscle. Your heart has 4 chambers. The Heart Valves (illustration) Four types of valves regulate blood flow through your heart: The tricuspid valve regulates blood flow between the right atrium and right ventricle.

Windows Phone 7: the complete guide After Windows Phone 7's grand unveiling at Barcelona's Mobile World Congress last month, Microsoft has circled back during GDC and its own MIX10 conference to fill in many of the holes in this story -- in particular, details around the app development ecosystem and how third parties can take full advantage of it have been focal points. Of course, it makes sense: a modern smartphone is only as good as its software catalog, and Redmond's clearly keen to show that it knows how very true that is. XNA -- the technology that underpins Zune games and a host of Xbox content -- figures prominently into the equation, but Silverlight is a huge, unavoidable component as well, making development for WP7 devices a starkly different experience for studios and independent code monkeys than in versions prior. The basic facts Windows Phone 7 is the successor to Microsoft's line of Windows Mobile phone operating systems. Gallery | 48 Photos Windows Phone 7 Series live gallery + See all 48 Hardware

Health Status Health Risk Assessments and Health Calculators Scanadu Raises $2M: “Check Your Body As Often As Your Email” Meet Scanadu, an innovative health tech startup I daresay you’ll be hearing a lot more from in the future. It’s not the easiest of tasks explaining what the company is building at this point, but let’s call it a personal, mobile, auto-diagnostics product – they refer to it as a Medical Tricorder. Founded in January 2011 by a team of entrepreneurs with diverse backgrounds, the roots of Scanadu actually go way back. One of the company’s founders, and its chief executive officer, is Walter De Brouwer – something of a legend here in Belgian entrepreneurial circles, and beyond. He says he had the basic idea for a personal health monitoring service back in 1999 when he was working at the renowned Starlab research institute, which he jump-started alongside MIT Media Lab founder Nicholas Negroponte. “Sci-fi stories are business plans in disguise,” De Brouwer tells me, referring to the invention of the mobile phone, which was inspired by the Star Trek communicator.

PSFK - the go-to source for new ideas and inspiration The Heart Disease and Cardiology Home Page Richard Avedon Richard Avedon (May 15, 1923 – October 1, 2004) was an American fashion and portrait photographer. An obituary published in The New York Times said that "his fashion and portrait photographs helped define America's image of style, beauty and culture for the last half-century".[1] Early life and education[edit] Photography career[edit] In 1944, Avedon began working as an advertising photographer for a department store, but was quickly endorsed by Alexey Brodovitch, the art director for the fashion magazine Harper's Bazaar. In addition to his continuing fashion work, by the 1960s Avedon had turned his energies toward making studio portraits of civil rights workers, politicians and cultural dissidents of various stripes in an America fissured by discord and violence.[10] He began to branch out and photographed patients of mental hospitals, the Civil Rights Movement in 1963, protesters of the Vietnam War, and later the fall of the Berlin Wall. In the American West[edit] Exhibitions[edit]

BVI (body volume index) The Body Volume Index (BVI) is a new measurement for obesity, proposed as an alternative to the Body Mass Index (BMI). BMI is based on a measurement of total mass, irrespective of the location of the mass, but BVI looks at the relationship between mass and volume distribution (i.e. where different body mass is located on the body). People of different age, gender or ethnicity will have different body shapes and recent studies have highlighted the limitations of BMI as an indicator of individual health risk.[1][2] BVI as an application for body shape and obesity measurement[edit] The Body Volume Index (BVI) was originally devised in February 2000 as a new, modern-day measurement for measuring obesity; an alternative to the Body Mass Index (BMI) which was originally conceived between 1830 and 1850. BVI is an application[3] that can be used on a 3D Full Body Scanner to determine individual health risk, whether the scanning hardware uses visible light optical information or otherwise.

Philippe Starck Philippe Starck is a French designer[1] who has become widely known since the start of his career in the 1980s[2] for his interior, product, industrial and architectural design work. Career[edit] The son of an aeronautical engineer, Starck studied at the École Camondo in Paris. An inflatable structure he imagined in 1969 was a first incursion into questions of materiality, and an early indicator of Starck's interest in where and how people live. Starck's iconoclastic designs brought him to the attention of Pierre Cardin who offered him a job as artistic director of his publishing house. A year later he designed the Asahi Beer Hall in Tokyo, a building topped with a golden spermatozoon. Alhondiga, Bilbao, 2010 For the past thirty years Philippe Starck has been designing hotels all over the world, including the Royalton in New York in 1988, the Delano in Miami in 1995, the Mondrian in Los Angeles, the St Martin's Lane in London in 1999, and the Sanderson, also in London, in 2000.
