The human body is composed of many different types of cells. Cells are composed of many different types of molecules. Molecules consist of one or more atoms of one or more elements joined by chemical bonds. An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons which can produce free radicals. The free radicals can start chain reaction in the body and cause damage to cells and important chemicals in the body. Free

Introduction to the Human Body Matching: Directions of the body Medial: Toward the midline of the body; opposite of lateral. Proximal: A structure is nearer to the trunk than is another part; opposite of distal. Distal: The part of the radius (arm bone) that is closer to the wrist than the elbow. Superior: The lung is above the diaphragm; above is described as… Anterior: Toward the front (the belly surface); another word is ventral. Matching: regional Terms Axillary: Armpit. Patellar: Kneecap

Editor’s Note: This occasional series of articles looks at the vital things in our lives and the chemistry they are made of. You are what you eat. But do you recall munching some molybdenum or snacking on selenium? Some 60 chemical elements are found in the body‚ but what all of them are doing there is still unknown. Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen‚ carbon‚ hydrogen and nitrogen‚ with a lot of that in the form of water. The remaining 4 percent

This system gives the body form and support‚ and protects the body while allowing it to move. Basically‚ the muscles in this system perform three important body functions: the movement of body parts‚ maintenance of body parts‚ and production of body heat. These muscles all consist of a mass of protein fibers grouped together‚ and most are of mesodermal origin. And almost all of the muscle fibers you will ever have or need were present at birth. Nearly half of your body mass is muscles‚ the largest

Nowadays‚ a Pitot tube would be of use as a speedometer on aeroplanes. It is also found useful in industries where velocity measurements are required‚ where an anemometer may not be the most efficient instrument to use. There are three types of pitot tubes: Pitot tubes‚ Static tubes‚ and Pitot-Static tubes. The simple pitot tube essentially consists of a tube bent at - usually - 90°‚ with an open end pointing directly towards the fluid flow. As the fluid flows in the tube‚ it becomes stagnant

It is the one essential nutrient that the human body cannot survive without. The adult human body is comprised of approximately 60% water‚ the body of a small child‚ infants for example is comprised of approximately 70% water. Water is found throughout the body
