Homeostasis Essay

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 means keeping a constant internal environment in the body. Homeostasis reaches from every cell up to the whole of the organs and the systems.

The actual word homeostasis means "steady state". Homeostasis describes how the body regulates its process to keep its internal conditions as stable as possible. Homeostasis is

Conditions in the body have to be controlled with narrow limits. This is called homeostasis. These conditions include water content, ion content, body temperature and blood glucose concentration.

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

25. Homeostasis refers to an organism's ability to regulate its internal environment despite changes in the external environment.

Homeostasis is described as the body's ability to maintain internally stable conditions. Each organ plays a huge role in maintaining this stability.

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.

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.

Homeostasis is maintaining constant internal conditions regardless of changing external conditions. It is important because it is the key to survival as without it the body would come to equilibrium with its environment which would result in death.

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.

The definition of homeostasis is the means or ability to keep the body stable in order to compensate for environmental changes.

What is homeostasis? Homeostasis is the ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. (McGraw-Hill) How does the body maintain homeostatic balance? Each organ system helps in some way to maintain homeostasis. However, the organ systems also work together to maintain a constant internal environment. There are seven organ systems (Integumentary, Musculoskeletal, Endocrine, Cardiovascular, Lymphatic, Respiratory, and Nervous) within the body. (McGraw-Hill)

Homeostasis is the term used to describe a body or system in balance, but one of the process the
