Question

Homeostasis: A Proletarian's Introduction.

Answer 1

This is just for people who would like to know more about our body's amazing aptitude to achieve equilibrium.

Answer 2

Introduction:

Simply put, homeostasis can be defined as “the equilibrium of the internal environment within an organism,” disturbances within which can “cause decreased function of the cell, organism and population” (McCarthy, 2010). Bailey (2014) describes homeostasis as “the ability to maintain a constant internal environment in response to environmental changes”. The function of homeostasis is to guarantee an active body’s temperature is regulated within suitable and safe parameters (Boorer, 2013) seeing as exercise necessitates high energy levels and the increase in the body’s heart, respiration and perspiration rates. Prototypically, homeostasis is the optimal constancy that permits the body to function in the most proficient manner (McCarthy, 2010) and both the cardiovascular system and the cerebral network function together to maintain a healthy balance. Although most obvious during exercise, homeostasis is, even in rest, acting to attain a state of balance. According to Boorer (2013), homeostasis denotes “the dynamic mechanisms that detect and respond to deviations in physiological variables from their ‘set point’ values by initiating effector responses that restore the variables to the optimal physiological range”. Increases in respiration clearly demonstrate the need for more oxygen and thus energy, and with the cells’ need for oxygen (delivered by capillaries and arteries) comes increases in the heart rate. Overall, the responsibilities of these homeostatic mechanisms include not only the monitoring of body temperature, but also of blood pressure, nutrient concentration and wastes within body fluids (Boorer, 2013). Aerobic respiration and the energy it creates causes the body’s temperature to rise and homeostasis acts to cool it down via sweat which is released through the eccrine and apocrine glands (Freudenrich, 2014). As exercise continues so too does perspiration, and the following experiment demonstrates how homeostasis was reached in an eight-minute period of exercise.

Answer 3

Hypothesis:

Exercise disturbs the heat, oxygen and carbon dioxide balance – as well as the heart, respiration and perspiration echelons – of an organism’s body which responds to restore it to an optimal state of equilibrium: thus homeostasis is achieved.

Answer 4

Conclusion:

Homeostasis is the body’s ability to assert equilibrium for every cell contained within its physiological being as a whole. Using a negative feedback loop, homeostatic regulation modifies the body back into a fixed range where maximum physical performance can be achieved despite external and internal influences that disrupt the balance. The postulation regarding the event wherein the human body is subjected to exercise and will result in several obvious signs – namely increased cardiac and respiratory rates, pulmonary circulation and perspiration levels – effectively encompasses the mechanism known as homeostasis and how, stimulated, homeostasis will monitor, regulate and return the body back to its most preferable performance parameters. Such was the experiment conducted to perceive. This experiment was relatively straight forward, thus future studies should definitely ensure a multitude of diversified subjects with differing backgrounds to enable a quantity of results and use more specialised measuring apparatus (eg. an electrocardiogram) to guarantee quality results. That said, this experiment effectively and efficiently establishes and expounds on the importance of homeostasis and proves how, that when under stress due to induced physical activity, the human body uses homeostasis to return the body back to its optimal performance status. The hypothesis asserts that the human body is one incredibly intricate and intelligent structure made up of many individual parts each with unique and pivotal designs and roles but the same overall function: to maintain life. This is an accurate supposition because the nerve centre in the brain responded to counteract the opposing strenuous forces when the subject was exercising; hence homeostatic regulation was achieved and can be interpreted as the reoccurring interaction between cause and effect in a perpetual endeavour to correct, restore and maintain optimal equilibrium. In summary, homeostasis, corresponding to the hypothesis, can be seen evidenced in the subject’s body as the physical response to exercise, with the increase in cardiac, pulmonary, respiration and perspiration echelons. The air-conditioned environment played a part in minimising the heat of the subject, yet the sheer physical exertion prevailed and homeostasis was required to return the body to optimal parameters. As aforementioned, it is recommended that more precise results could be gained by repeating the experiment in an outdoor environment open to the elements of sun, wind and humidity. The results of this investigation clarify beyond doubt that, provided with sufficient physical challenges, the human body does and will demonstrate homeostatic traits in an endeavor for systemic equilibrium.

Annotations:

I composed this text as part of my university degree and as you read you will see references to an experiment conducted; if you would like to see the outcome of the experiment let me know via email.

Answer 6

okay :)

Answer 7

Ah where could I begin Prae, this is magnificent. I totally adore your write style it is clear and understandable. But definitely not boring; idk but when I read lab reports I wanna fall asleep; but the way you wrote this kept me hooked on to the subject. However, I am aware that teachers especially professors always have at least a flaw to point out, though, I am neither of those so I am freely allowed to tell you that this is perfect, Praessie! \ (•◡•) /
