Body Temperature And How It Regulate Homeostasis

Homeostasis is what allows our internal system to maintain at a constant condition. In order to maintain equilibrium the body must communicate using the control system. It is essential that the body monitors its conditions whether that be blood pressure, thirst sensation or body temperature (this is either gained or lost). Negative feedback is most important and comes first, this allows for the body to correct itself and get back to a set point when it is off track. There are three components that link with this feedback. A sensor (receptor) sends signals to the control center that something is unusual, the control center compares the many values of our normal body range and decides

Usually, homeostasis should be maintained using the stimulus-response model. In this model, the stimulus is the changes or variations in the internal environment of your body, and will be detected by receptors. Then, the control centre (your brain and spinal

Homeostasis is a biological process that maintains a constant internal environment, regardless of what is going on in the external environment. This process ensures the bodily functions and chemicals are kept in a state of balance which in return allows the body to function optimally. Homeostasis requires coordination of the hormonal (endocrine system) and nervous systems, which together regulate the activity of the body’s organ systems. The regulatory activities are constantly adjusted in response to stimuli (change) from both the internal and external environment. A change influenced by the external environment can cause a state in the body that will take it away from the normal, the body will act to counteract this change and return the internal environment back to a steady state. This is negative feedback. Negative feedback has a stabilising effect reducing changes from a set point and returning internal conditions to a steady state. Most body systems e.g. controlling blood glucose levels, obtains homeostasis through negative feedback which makes the negative feedback system critically important in obtaining homeostasis. However there is also positive feedback which is a system that results in the escalation of a response to a stimulus. It causes instability in the system and is used when there is a specific outcome required. Positive feedback ceases once the natural resolution is reached e.g. baby is born, pathogen is destroyed, blood clot forms. This system is not used

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.

I will initially start this assignment by explaining what homeostasis means. Homeostasis means the body’s ability to maintain a steady condition for cells live in even if the surroundings change around them. Cells rely on the process of homeostasis (Wright, 2007). I will start with thermoregulation. Thermoregulation is the method that keeps the body’s core temperature at the optimum working range, which is 37 degrees Celsius in order to function adequately. Homeostasis helps thermoregulation, osmoregulation, and sugar regulation to stay in a stable equilibrium, for this process, the whole body’s internal organs and the skin have to work together (Books, 2012).

Homeostasis is a key concept in biology. As stated by Bright Hub, 2014 “Homeostasis in a general sense refers to stability, balance and equilibrium.” It is a process by which the internal conditions of living organisms remain constant, or within a normal range, regardless of their external environment (Dummies.com, 2014. Homeostasis is controlled by a specific section of the brain called the hypothalamus (msichicago.org, 2014). The hypothalamus is comprised of neurons that form the main link between the nervous system and the endocrine system, which play a focal role in regulating a person’s internal temperature, hunger and thirst, blood pressure, and daily circadian rhythms (msichicago.org, 2014).

What is Homeostasis? According to Study.com, Homeostasis is a process of how our bodies keep a well-balanced internal condition. In addition to, Homeostasis occurs for anything that we do. This includes, eating working, exercising and other activities. Homeostasis is important because it maintains our bodies well and makes adjustments when needed. Without Homeostasis, our bodies would not function properly. If we did not have Homeostasis, we would get diseases and get ill.

Humans are endotherms and their physiological thermoregulatory responses are controlled by the hypothalamus in the brain. The hypothalamus receives information from both receptors in the hypothalamus that monitor core body temperature, and receptors in the skin which register external temperature. This information allows the hypothalamus to regulate body temperature.

Homeostasis is the body’s way of maintaining a steady balance in the internal organs regardless of fluctuations in the external environment. Homeostasis is an important function in all humans and animals as keeping a stable environment requires constant adjustments as the environment changes. Homeostasis requires the coordination of both the endocrine (hormonal) and nervous systems; they regulate the body’s internal organs.

Homeostasis. The control system behind maintaining an equilibrium in its internal environment. In humans the homeostatic control system is powered mainly by negative feedback loops to maintain things such as. Internal body temperature, blood glucose levels, etc… This essay focuses on the maintaining of the internal body temperature and the methods used to stop the athlete's body going in either hypothermia(dangerously low internal body temperature) or hyperthermia(dangerously high internal body temperature).

Negative feedback mechanisms do affect how hormones work and furthermost endocrine glands are beneath the influence of negative feedback mechanisms. With knowing this negative feedback lowers the abnormality from an ultimate standard value in the body, and is very important in upholding homeostasis. For example knowing negative feedback mechanisms affect the human body is the start, they do so by modifying the body by temperature. As the temperature increases from the ultimate standard value, the thermostat identifies the modification and initiates the air-conditioning to perform and cool its surroundings. The air conditioning is turned off after the temperature influences the thermostat and establishes the ultimate standard value. The hypothalamus

Homeostasis is a biological property of internal body environment. It is variable but usually stable and proximately constant. Generally, homeostasis is necessary for body maintenance and regulation to reach balance and steady state. Homeostasis mechanism has several parts working together to set off a homeostasis. The stimulus which can be external or internal variable changes. The sensor of the body receive the message of stimulus, then deliver the signal to control center then trigger a response of effector. Last but not least, the response helps to returns to normal state. There have two kinds of feedback mechanisms of homeostasis- positive feedback and negative feedback. Most cases of homeostasis control are negative

The homeostatic system is what works to maintain the physiological consistency within the internal environment of the body despite fluctuations within the external environment. The homeostatic system is constantly active in order to maintain an optimum internal environment to enable the body to work as efficiently as possible, it consists of receptors, a main control centre and effectors. This system is activated by an external stimulus producing a change within the internal environment which is detected by receptors and then corrected. The body has two different types of responses; these are either nervous responses or hormonal responses. The nervous responses are where the nervous system responds to stimuli by sending electrical pulses along neurons which tell their target cells what its response should be. This response is near instantaneous, whereas hormonal responses within the endocrine system occur at a much slower rate. Hormones are synthesized away from their target cells and then travel through the bloodstream or intercellular fluid until they reach these cells. Once entering or signally the cell the target cell must go through transcription, translation and protein synthesis before the hormone is able to do its intended purpose. Because of their longer process a hormonal response is slower than a nervous response; however the effects of the hormonal response are longer lasting. The body achieves homeostasis through negative or positive feedback. The positive

Temperature control is the body’s natural way of warming and cooling its self, allowing it to stay at one particular temperature (37oC or 98oF) Receptors in the skin detect changes in the external temperature. They pass this information to the processing centre in the brain Hypothalamus. Hypothalamus is a processing centre in the brain that controls body temperature and is in charge of sending out signals to other conductors. It does this by triggering curtain mechanism such as goose bumps, sweet gland, shivering and automatic responses i.e taking off or putting on clothing when hot and cold. These automatic mechanism helps’ the body maintain and control its preferred temperature, this helps keep the organs, enzymes and cells working at a good speed keeping you healthy and stable.

Homeostasis is what physiological systems in our bodies do in order to maintain a stable internal environment. Stability is held together by the coordinated responses of the components involved to any stress or unfamiliar situation that the human body is put under that could disrupt its normal functioning conditions. Homeostasis must be maintained constantly in order for our bodies to be able to function properly and not under stress which could have major effects later on in life.
