The Concept of Homeostasis Particularly in Relation to Temperature Control

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

The purpose of this lab is to analysis goldfish an ectothermic animal affect toward different temperature ranges. The reactions toward the temperatures are taken upon the term of homeostasis, which is regulation for organisms to maintain a steady state while adapting to the conditions that are favorable for survival (Encyclopedia Britannica). In order to achieve a successful homeostasis, many animals use different methods of thermoregulation, which helps maintain the internal temperature of animals. Many methods vary whether the organisms is an endotherm or ectoderm. An endotherm, which includes mammals and birds, is a warm-blooded animal, which maintains a constant body temperature not influenced by the environment (Britannica).

Including human, most mammals and birds are homeotherm, whose body temperature maintains relatively constant,

Somewhat more precise descriptions can be made by using the terms poikilothermic and homoiothermic. The body temperature of poikllotherms is relatively variable, while that of homeotherms is relatively constant.

In the human body the internal temperature is maintained at 37 degrees Celsius and this is maintained as a result of homeostasis. Homeostasis is the process of balancing or keeping a stable internal environment in the body. A majority of organ systems in the body contribute to homeostasis, however there are two very important organ systems that play a massive role within this process, and they are the endocrine and nervous system. Both are crucial as they permit communication in the body and the integration of cells as well as tissue functions.

Thermoregulation is a process by which the body temperature is controlled and maintained within a range that enables the organism to function efficiently when variations occur in the temperature of the surrounding environment. This is important to ensure that the blood flowing through vital organs like the brain and the heart are kept at an ideal and constant temperature (Homeostasis, n.d.). In this lab, mealworms are used. Although referred to as a “mealworm”, it is not a worm but instead the larvae of the darkling beetle species called Tenebrio molitor (Gomez, n.d.; Tenebrio molitor, n.d.). Usually, the heat generated from cellular metabolism determines body temperature, but mealworms are ectotherms, which are organisms that depend mostly

Homeostasis means “‘steady state,’ referring to the maintenance of internal balance” (Reese 875). There are many ways homeostasis can be achieved by an animal. For instance, let’s say a dog is in a cold environment and in order for its body to maintain a normal body temperature it begins to shiver. When a body temperature decreases a message is sent to the hypothalamus (which is like an internal thermostat) and then activates a warming mechanism. Once the brain sends this message to the blood vessels, the blood vessels then begin to constrict, as an outcome, their skeletal muscles begin to contract, causing them to shake and begin to shiver. When shivering occurs heat is generated and as a result the body temperature increases and its body begins to warm up. First, as our

The Effect of Temperature on Animal Respiration Renee King 001420538 TA: Oliver Biology 3U03 L01 This lab examined the effect of temperature on the rate of oxygen consumption by measuring VO2. Effects were observed in goldfish, frogs, and mice, which each use different mechanisms for thermoregulation. The average rate of oxygen consumption by goldfish increased from an average of 0.175 mL g-1 h-1 at 5֯ C to 0.288 mL g-1 h-1 at 25 ֯C which was a 64% increase. The average rate of oxygen consumption by the frog was higher at 5֯ C than at 25 ֯C. At both temperatures, the rate of oxygen consumption increased over time.

The control of body temperature –thermoregulation. This is an example of the nervous and endocrine systems working together.

A really good example of homeostasis is the body keeping the average temperature of 98.6 degrees.

When the body has an open wound that overwhelms the clotting mechanism and leads to a serious hemorrhage one would receive a shock from the wound. This shock causes the arteries to loosen, which reduces the amount of pressure and slows down the blood loss. This activates the baroreceptors that cause the stimulation of the heart and the constriction of peripheral blood vessels.

Hibernation is a period where animals enter a dormant stage throughout the winter months. In regards to the animal domain, only mammals are able to maintain their body temperatures without the aid of their environment. Being, “warm blooded” allows for these animals to regulate their body temperature without restraints from the environmental temperature. Animals lives revolve around whether their actions are beneficially contributing to their overall fitness.

Homeostasis is the process of maintaining and regulating the body’s own internal condition and is extremely critical for proper body function; without it we could die. To maintain homeostasis, our body has created a system of positive and negative feedback loops that are controlled in the brain (specifically the hypothalamus in most mammals). This occurs when the product or output of something, like ion concentration, blood calcium or glucose levels, change in response to the body telling itself there’s too little or too much of it. A positive feedback loop will increase the output, or product, as a result of an amplified reaction to make it happen faster. A negative feedback loop, on the other hand, is the reduction of a product to lower it

The human body is easily affected by external environments, as such heat stroke or hypothermia may occur if the body cannot regulate the parameters back to constant through the homeostatic mechanism. In order to maximize our bodies’ functions, appropiate heat lose or heat gain mechanisms are necessary and however, if we cannot ensure the parameters are constant since like when the external environments are too cold, heat will be stored inside our core body for a larger extent but not for the limbs. Therefore, when we meet very cold environments, we can survive for a longer time through the help of homeostasis and keep our body functional. But since we cannot exceed the limits of parameters, hypothermia in this case may happen when homeostasis

Paradigms likely to influence my inferences, particularly with respect to artiodactyls, include: thermoregulatory behaviour, endothermy, homeothermy, heterothermy, adaptive heterothermy and heterothermy induced by water and/or energy stress. Competing paradigms of heterothermy (adaptive vs. stress induced) are particularly pertinent and continue to be debated (testing the paradigm and Kuhn’s period of ‘revolutionary science’ (82)). No neutral evidence exists to compare these paradigms (cf. positivism, (80)), however they are not entirely incommensurable (Kuhn’s incommensurability, (85-87)). In addition, although each paradigm possesses its own supporting evidence (albeit it being paradigm-relative (84, 88)); limited data and evidence exists to judge, compare and choose between the two paradigms (Kuhn’s theory-ladenness of data (88)). In anticipation of my findings, I am aware that I am more aligned to the paradigm of water and/or energy induced heterothermy and will remain conscious of this throughout my method of enquiry, evidence analyses and scientific
