High Altitude Training High altitude training is a method that has gone through extensive research over the past years. It is an interesting trainingprocedure that is being adopted by Olympic and professional athletes worldwide. Many professional athletes, today, include a section of high altitude training in their routines. They train at higher altitudes to prepare for lower altitude oxygen level.
The idea behind this form of training is that if an athlete can get used to the tough environment that is present at higher altitudes, he or she would have experience a higher level of endurance when traveling to lower altitudes. The reason is that at higher altitudes, there is lesser amount of oxygen for the body and muscles. Therefore, the excess oxygen will help avoid the early production of lactic acid and keep heart rate lower even when the athlete is working harder at sea level. (Smith, 2005)
The trick to high altitude training is a process known as acclimatization. This means that athletes must give time to their bodies to get used to the increase in altitude, and decrease in oxygen levels in the atmosphere. For instance, when an athlete reaches, say 5000 feet, he must spend some days there so that the body acclimatizes to the conditions present there before moving on to higher altitudes. After acclimatization to higher altitudes, when the athlete returns back to sea level, his endurance level and performance is better.
High Altitude Training and Respiration
As the oxygen levels at higher altitudes decrease, there are a number of changes that the body undergoes in the process of acclimatization. Firstly, the depth of respiration increases. The pulmonary arteries go through an increase in pressure, forcing blood into those parts of the lung which are not utilized under normal circumstances. (Curtis, 1999)
Along with increasing the production of red blood cells to carry oxygen, the body also steps up the production of a specific enzyme that eases the discharge of oxygen from hemoglobin to the body tissue. (Curtis, 1999)
Exercise and Carbon Dioxide Levels
As we know, the air in the atmosphere consists of 78% nitrogen, 21% oxygen and 1% water vapor, carbon dioxide and other gases. This is the proportion of gases you inhale during normal breathing. However, 6% of oxygen is breathed out together with carbon dioxide and other waste products. (Science Fair 2003: Does Exercise Affect the Amount of Carbon Dioxide Exhaled, 2003)
During exercise, the body needs more energy which is provided to it through the chemical reaction of oxygen and glucose. This, in turn, means that during exercise, the body needs more oxygen. This extra demand in oxygen is provided through deeper and faster breathing.
However, it is important to note that the respiration of the body is controlled by carbon dioxide and not oxygen. During exercise, the production of carbon dioxide in the body is increased. A part of the brain, known as medulla, is responsible for measuring the level of carbon dioxide in the blood. When the medulla detects the increase in the carbon dioxide levels, it responds to it by increasing the respiration rate. (Science Fair 2003: Does Exercise Affect the Amount of Carbon Dioxide Exhaled, 2003)
As discussed, high altitude training is a great form of training for professional athletes who want excellent performance and endurance results in competitions. Although, critics argue that the advantages of high altitude training do not last for a long time after the athlete returns to sea level, it is still practiced by the top level athletes to train for competitions, a month or two before the big event.

...?Organism Physiology of the Organism The of the organism, which I am going to discuss in this paper, is ‘Frog’. Frog is an amphibian, whichhas its presence on the earth for millions of years. In this paper, we will talk about its main organs and will discuss how it has evolved physiologically to suit its external environment. Frog and Its Environment Researchers have done a lot of research on the physiology of frog. Some of the main organs of a frog studied extensively by the researchers include head, trunk, belly, webbed foot, hind leg, front leg, tongue, eye, nostril, and tympanum. Let us get an overview of some of the main organs of a frog in order to get an understanding of the roles...

...? Causes of diabetes Research proposal Insert Grade Introduction Indeed, diabetes has become a major global crisis due to its effects and scale of prevalence. It has led to an unproductive society that directly impacts its growth. Its physiological aspect is that many studies show that it majorly arises from the lifestyles that people lead (Dijk, 2012). The outcome of diabetes is profound in that it also affects the physiological well-being of a person. Dijk (2012) states that a lot of people suffer from type 2 diabetes which has been found to be on the rise with the rise in obesity. Study also shows that with its faster economic growth, Asia has become the epicenter of the disease. According to Struijs...

...Ans 1a Ans b Answer b: Glucose is preferred over lactose for growth and metabolism, as it is clearly indicated in data the activity of -galactosidase induced after 10 h of growth. At this time -galactosidase will cleaved lactose to make glucose. E.coli prefers glucose over lactose and start utilizing glucose in initial stage. Once glucose gets exhausted it switches over to lactose. Similarly in case of time v/s dry weight plots it indicates biphasic (diauxic growth) growth curve. There is steady increase in dry weight as soon as culture was inoculated and reached to plateau around 10h followed by lag phase for one hour and again there is increase in dry weight. This lag phase needed for organism to switch over to new carbon source...

... of the gastrointestinal function. (15) Gastrointestinal function is regulated by the sympathic and parasympathic autonomous nervous system. The parasympathetic innervation of the gastrointestinal tract is provided by the vagal nerve (upper part of abdominal viscera) and the pelvic nerve (lower segments of colon and rectum). The sympathetic innervation is supplied by the branches of the paravertebral chain, prevertebral coeliacomesenteric and caudal mesenteric ganglia. Parasympathetic stimuli activate the peristalsis and secretion whereas the sympathetic stimuli produce opposite effect. References: Guyton, A.C. & Hall, J.E. 2000.

...Skeletal System Essay DESCRIBE THE DEVELOPMENT AND GROWTH OF BONES Ossification or osteogenesis begins towards the end of 8th week of gestation. All bones begin as mesenchymal condensations during the embryonic period. The fibrous condensations ossify into the membrane or dermal bones and the cellular condensations ossify in to hyaline cartilages (Gardner, 856-862). Thus, the skeletal pattern is formed in cartilage and connective tissue membranes. From here, bone development continues throughout adulthood. The 3 cell types involved in the development, growth and remodeling of bones are osteoblasts, osteocytes and osteoclasts. While osteoblasts are bone-forming cells, osteocytes are mature bone cells and osteoclasts break down... System Essay...

After the evaporation, the cooled blood returns to the core of the body this regulating the temperature. Blood flowing through the dermis is regulated when one’s body heat is stable depending on the changes in ambient temperature. This is to ensure that differences in temperature between the environment and the skin remain constant thus preventing heat loss and attaining a constant temperature (Yagiela,...
