THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in altitude have a profound effect on the human body. The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body's ability to provide adequate oxygen to be utilized in cellular respiration. With an increase in elevation, a typical occurrence when climbing mountains, the body is forced to respond in various ways to the changes in external environment. Foremost ...

... taneously as the body acclimatizes to the higher elevation. Moderate AMS includes a severe headache that is not relieved by medication, nausea and vomiting, increasing weakness and fatigue, shortness of breath, and decreased coordination called ataxia (Princeton, 1995). Normal activity becomes difficult at this stage of AMS, although the person may still be able to walk on their own. A test for moderate AMS is to have the individual attempt to walk a straight line heel to toe. The person with ataxia will be unable to walk a straight line. If ataxia is indicated it is a clear sign that immediate descent is required. In the case of hiking or climbing it is important to get the affected ind ...

- Electrocardiogram - 797 words
Electrocardiogram Electrocardiogram Lab Introduction Electrocardiograms are used to obtain information about the function of the heart. An ECG is a recording of the electrical activity of the heart made from electrodes placed on the surface of the skin. Salt solutions are good conductors of electricity and can transfer electrical activity to the skins surface. An ECG tracing shows the sum of the electrical potentials generated by all the cells of the heart at any moment (Silverthorn, 1998). Each point reflects depolarization or repolarization of a portion of the heart. Depolarization is the signal for contraction. There are three major components of an ECG: the p waves, which corresponds to ...

... n 5.7 hours of sleep followed by 7.4 hours awake and 5.8 hours of sleep. The big difference between short haul and long haul was the external environment such as light and activities that were different from the pilots normal circadian system; this was due to flying over as many as 5 different time Zones. The internal clock system was changed from the normal 24 hours to a clock system of 25.7. This made the sleep episodes unable to adapt to the changing time Zones. The most important information gathered from the study was that it showed that there are times of good sleep and times of bad sleep. The current regulations regulate the off-duty times to allow for sleep and rest, but they do ...

... e (Whatever is, is right, An Essay on Man, 1732-34) it is hard to see any useful role of the basophil/mast cell in human physiology. The mast cell is the essential effector of immediate (Type 1) hypersensitivity reactions, which produce only misery, dysfunction, and occasionally death for the hapless host. E. Lymphocytes In the immune/inflammatory response, if the neutrophils and monocytes are the brutes, the lymphocytes are the brains. It is possible to observe the horror of life without lymphocyte function by studying the unfortunate few with hereditary, X-linked, severe combined immune deficiency. Such individuals uniformly die of systemic infections at an early age (except for the bu ...

- Mozart Effect - 1,690 words
Mozart Effect Although it is only in recent times that scientists have started to document the effects of music, the qualities of music were understood even in earliest times. Evidence suggests that dance and song preceded speech, which means that music is the original language of humans. Researcher's have found that about two-thirds of the inner ear's cilia resonate only at the higher frequencies that are commonly found in music (3,000 - 20,000 Hz). This seems to indicate that primitive humans communicated primarily through song or tone. The ancient Greek philosopher Pythagoras, best known for his work in mathematics, thought the whole universe was comprised of sounds and numbers. There has ...

- Swimming Bio Mechanics - 1,687 words
Swimming Bio Mechanics Natural forces affect the movements of swimmers in water. And it is often useful to know how these forces act. This knowledge will help swimming teachers and coaches analyze swimming skills and assist them to understand how these forces influence movement, so that they can encourage beginners to be better swimmers or good swimmers to achieve there optimum potential. Biomechanics is the branch of science that is concerned with understanding the relationship between a living body's structure and function relative to movement. In this paper the swimming form of the front crawl stroke will be analyzed, which may result in improvement in the following areas: Improving perf ...

- Ufo Kinds - 3,432 words
UFO Kinds Ever since US Air Force Pilot Kenneth Arnold coined the term Flying Saucer, on 24th June 1947, after allegedly encountering nine disk shaped objects while out flying over the Cascade Mountains, the world wide sightings of such objects, has increased logarithmically. By 1957 the furor over UFO sightings showed no sign of abating and the sightings had now been awarded levels of classification by US Astronomer, Allen. J. Hynek. Hynek created three categories for UFO encounters: Close encounters of the first kind: nocturnal lights, daylight disks, the second kind: Physical affects left by UFOs, marks on the ground, car engines stalling and finally close encounters of the third kind: th ...
