"Physiologies" redirects here. For other uses, see Physiology. The study of the human body involves anatomy and physiology. Structure The human body has several body cavities the largest of which is the abdominopelvic cavity. Composition 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 & FunctionWithout 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.
Body proportionsWhile there is significant variation in anatomical proportions between people, there are many references to body proportions that are intended to be canonical, either in art, measurement, or medicine. Similarly, in art, body proportions are the study of relation of human or animal body parts to each other and to the whole. These ratios are used in veristic depictions of the figure, and also become part of an aesthetic canon within a culture. Basics of human proportions Human proportions marked out in an illustration from a 20th century anatomy text-book. Different proportions in different people. It is important in figure drawing to draw the human figure in proportion. The proportions used in figure drawing are: Western ideal Leg-to-body ratio Another study using British and American participants, found "mid-ranging" leg-to-body ratios to be most ideal.

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. The 2005 NHL-NHLPA collective bargaining agreement introduced re-entry waivers. The 2013 collective bargaining agreement eliminated re-entry waivers.

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.

Proportions for different heightsWindows Phone 7: the complete guideAfter 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

Critical Friends Group professional learning communities consist of approximately 8-12 educators who come together voluntarily at least once a month for about 2 hours. Group members are committed to improving their practice through collaborative learning. How did the idea of CFGTM communities develop? In 1994, the Annenberg Institute for School Reform designed a different approach to professional development, one that would be focused on the practitioner and on defining what would improve student learning. Since the summer of 2000, Critical Friends Groups training is coordinated by the National School Reform Faculty (NSRF) at the Harmony Education Center in Bloomington, Indiana. What are the characteristics of a professional learning community? Professional learning communities can develop when there is: A professional learning community is enhanced when there is: There are a wide variety of professional learning communities (PLCs).
Female Skeleton AnatomyScanadu 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.
