Fiber Optics Assignment Many modern medical materials and equipment work on a principle which is beyond the capacity of human transducers. Comment and discuss the working principles of an endoscope‚ uteroscope or a rectoscope showing the illuminating path‚ the image path‚ transmission path and the liquid transfer or operating instrument ducts‚ showing the position of suitable valves. This will therefore explain how light travels through an optical fibre and show how such

What Is the Function of the Spleen? By Jessica Pestka‚ eHow Contributor updated: April 28‚ 2010 The spleen is an internal organ‚ about the size of a fist‚ found in the human abdomen. The spleen functions as part of the immune system and contributes to the production and storage of blood cells as part of the circulatory system. Although the spleen is an important organ‚ it is not vital for human survival. Function of the Spleen The majority of the spleen’s functions are related to the immune

“The structures of body systems are determined by their functions”. Discuss this statement‚ focussing on the Circulatory System. You should include diagrams and relevant examples in your essay. In order to survive it is necessary for every cell in the body to exchange materials as not all cells are in contact with the external environment; we rely on the circulatory system to do this which is composed of the heart‚ blood vessels and blood. The heart consists of four chambers two atria and two ventricles

Fiber Optics Fiber Optic Cable Facts "A relatively new technology with vast potential importance‚ fiber optics is the channeled transmission of light through hair-thin glass fibers." [ Less expensive than copper cables [ Raw material is silica sand [ Less expensive to maintain If damaged‚ restoration time is faster (although more users are affected) [ Backbone to the Information Superhighway Information (data and voice) is transmitted through the fiber digitally by the use of high

Fiber optics is a cable that is quickly replacing out-dated copper wires. Fiber optics is based on a concept known as total internal reflection. It can transmit video‚ sound‚ or data in either analog or digital form . Compared to copper wires it can transmit thousands of times more data (slide 2) . Some of its general uses are telecommunications‚ computing‚ and medicine. <br> <br>The very first "fiber" was made in 1870 by the British physicist John Tyndal. In this experiment that he showed to the

definition of fiber may be needed. New products are being developed or isolated that behave like fiber‚ yet do not meet the traditional requirements of fiber‚ either analytically or physiologically. Without an accurate definition of fiber‚ compounds can be designed or isolated and concentrated using available methods without necessarily providing beneficial health effects‚ which most people consider to be an important attribute of fiber. Most of us are familiar with the terms "soluble fiber" and "insoluble

Understanding Your Fats and Fiber SCI/241 June 13‚ 2013 Understanding Your Fats and Fiber According to Face the Fats the bad fats are trans fats and saturated fats‚ both of these fats raises bad cholesterol levels in the blood. Monounsaturated fats and polyunsaturated fats can lower bad cholesterol levels and are beneficial when consumed in moderation. Taking in too many fats regardless of what kind they are can eventually lead to to many calories which can lead to weight gain. High levels

used in processed foods such as baked goods. Fiber and lipids serve two separate functions that both help keep the body healthy. Fiber absorbs cholesterol and helps to slow the amount of glucose the body absorbs. Fiber helps collect waste and build it into one entity rather than the body having diarrhea and waste just running through the body. It allows the waste to form into a single mass before it is passed through the body. Lipids help your body collect and store energy for use
