Homeostasis Term Paper

Homeostasis is a characteristic of life in which all Living things maintain. some of the traits of Homeostasis are perspiration and some form of breathing and other natural body functions. An example of a negative feedback mechanism is a Thermostat If the heat is turned on and is set at 80 degrees the heat is turned on, If the temperature drops below 80 degrees, After the heater heats the house to 80 degrees, it shuts off keeping the desired temperature. An example of a positive feedback system is when a baby is born. while the mother is in labor, a hormone is released that boosts and quickens her contractions. The more contractions causes more of that Hormone to be let out and it continues to goes on until the

Homeostasis is the way that a system functions to control and maintain the body’s physiological systems. This system consists of:

homeostasis. Joint homeostasis is maintain with the balance between build up mechanism and break down mechanism of the joint. Imbalance homeostasis occurred when anabolic effect is slower than catabolic effect of the joint. This will result in joint instability (Goldring MB, 2006).

Homeostasis is vital for us humans. However, homeostasis imbalance can occur when cells in the body malfunction or experience a deficiency such as malnutrition (results from unhealthy diet) or when cells are exposed to toxins.

_There would be a greater change in the resting membrane potential in K+ than in Na+ because of more K+

In order for our bodies to function effectively, there is a series of events that occur at the biological and chemical level in our bodies. These events enable the human body to withstand various stresses that may be imposed on our bodies. These “events” that occur are more specifically known as the process of homeostasis. In this essay I will be discussing the process of homeostasis and how homeostasis works. Furthermore, I am discussing thermoregulation, osmoregulation, sugar regulation, and negative feedback which are all components of homeostasis.

All living things strive towards one goal: homeostasis. Homeostasis is a state of equilibrium reached through physiological processes. In order to maintain homeostasis, living things use cells, tissues, organs, and organ systems to counteract physical changes. Using a variety of different tissues, organs are formed to accomplish specific tasks. The four main types of tissues are epithelial tissue, connective tissue, muscular tissue, and nervous tissue. Several sublevels exist for each type of tissue.

Production of H+ will cause plasma pH to fall below 7.4. Normally, increases in H+ concentrations are buffered mostly by haemoglobin, however buffers can only resist small changes in pH. The HCO3- levels increase slightly, but are likely to still remain within normal levels of 22 to 26 mEq/L. This is because equilibrium changes in concentrations is slight compared to the large compensatory changes (1). Renal mechanisms can assist in excreting H+ and reabsorbing HCO3-.

Homeostasis Homeostasis works to maintain the organism's internal environment, where the body's processes are able to function at a level that would allow life to continue in that organism. The three systems which are controlled by homeostasis are the respiratory, cardiovascular, and muscular systems. Changes to the cardiovascular system are often a result of changes in the activities of other systems.

Homeostasis is when a livening system has the ability to keep an internal balance. The internal balance includes body temperature, digestion, and fighting of sickness.

According to Thompson (2011), most DKA patients experience dehydration which entails tachycardia and hypotension. In order to balance the system, an elimination of CO2 by the respiratory buffer system occurs as the serum pH of the patient becomes more acidotic. Along with an imbalance of the electrolytes, dehydration can also cause renal and cardiac problems. An increased respiratory rate as well as Kussmaul respiration (deep quick breathing) has also been shown by assessment (Thompson, 2011). Most patients suffering from DKA have been observed to exhibit Kussmaul breathing, with deep and rapid breathing. This is linked to regulation of acid-base; to balance the overwhelming acidosis and in an effort to lower the carbonic acid’s levels created from carbon dioxide (a weak acid), the system of respiration is triggered (Thompson, 2011).

The pH balance in the body, better known as the potential of hydrogen, is the measure of consistency in acidity or alkalinity in a solution. The value is measured on a scale that ranges from 0-14, but is considered normal when within a range of 7.35 to 7.45.When the body maintains the ranges of pH from 7.35 to 7.45 the immune system within the body operates properly. The lower the pH level, the more the acidic solution, the higher the pH level, the more alkaline the solution is. However, when the solution consists of neither it maintains a neutral balance of 7.

If the pH of the blood of all human beings on earth was not maintained a crisis would occur. Organisms use homeostasis to maintain a necessary blood pH. Homeostasis is a process where internal conditions are maintained for survival. If homeostasis is not successful death may occur. Many times homeostasis occurs due to a concentration gradient. Also, the composition of fluids outside the cell must be kept stable in order to maintain homeostasis. The regulation of the blood pH occurs in order to keep a stable acid-base condition. Many effects will occur if the blood pH is not maintained therefore there is multiple adaptations helping to maintain it.
