Human anatomy

Human anatomy
"Physiologies" redirects here. For other uses, see Physiology. The study of the human body involves anatomy and physiology. The human body can show anatomical non-pathological anomalies known as variations which need to be able to be recognised. Physiology focuses on the systems and their organs of the human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis. 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 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: Body proportions While 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[edit] Human proportions marked out in an illustration from a 20th century anatomy text-book.

National School Reform Faculty What is a Critical Friends Group® learning community? 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.

From the moment it begins beating until the moment it stops, the human heart works tirelessly. 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.

Images Of Female Athletes The images below show an incredible variety of women, ranging in weight, height, race and proportion. What they all have in common is that they are professional athletes at their physical peak. The images, taken by photographer Howard Schatz for his 2002 book, Athlete, recently resurfaced, reminding us of the diversity of women's bodies. Schatz interviewed and photographed hundreds of athletes for the book, a project he says was inspired by his interest in human variation and the musculoskeletal system.

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.

Proportions for different heights BMI (body mass index) A graph of body mass index as a function of body mass and body height is shown above. The dashed lines represent subdivisions within a major class. For instance the "Underweight" classification is further divided into "severe", "moderate", and "mild" subclasses.[1] The body mass index (BMI), or Quetelet index, is a measure for human body shape based on an individual's mass and height.
