Why Does The Body Need To Maintain 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

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 the process of maintaining a fairly constant interval environment. Homeostatic mechanisms help us to be independent of our external environment. It helps us regulate our body temperature, pH, concentration of dissolved substance in the body fluids, concentration of glucose in blood, concentration of oxygen and carbon dioxide in the blood and body fluids, blood pressure and concentration of metabolic wastes. Without it, we wouldn’t be able to survive and adapt to our environment.

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

Homeostasis is the maintenance of a constant internal environment. The maintenance of homeostasis can occur through the nervous system or through chemical stimulation and changes are achieved and controlled by the homeostasis regulation mechanisms

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.

The circulatory system maintains homeostasis, by the controlled and continuous flow of blood that reaches each cell in the body. This allows the mechanisms within the circulatory system to ensure that every cell maintains a constant and balanced internal environment!

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.

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 maintenance of near constant conditions/ state of the internal environment of an organism, this is important for the organism as it needs to maintain a near constant internal environment, it does this by allowing the body cells to function at optimal levels so internal and external influences don’t affect the state and conditions of the organism. An example of a homeostatic system is blood glucose regulation. It is the process that is maintained by the body for the levels of blood sugar; glucose, Glucose regulation is a process in the body that keeps it in homeostasis; insulin and glucagon are the main hormones involved in the process. Blood glucose is produced from food we eat, especially carbohydrates, fats and proteins, this is the main source of energy for the human body. Blood glucose is transported to the cells by the circulation and into cells by glucose transporters; some are regulated by insulin. Insulin is one of the hormones produced by the pancreas in which regulates the glucose levels in the blood around the body. Glucose is needed for respiration and the concentration levels of glucose in the blood is important to be kept and maintained at a near constant level (70 to 115mg, in a normal adult). Hyperglycemia means high blood glucose levels, this can caused by several factors such as poor food/ diet and physical activity choices and even illness. The body needs glucose to properly function due to being

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.

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