What is Homeostasis?
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).

This process is known as homeostatic imbalance (Human Homeostasis, 2014). Consequently, homeostatic imbalance often leads to illness as the body’s cells either receive too little or too much of a particular substance (Disease as Homeostatic Imbalance - Homeostasis, 2014). Diabetes, especially type 1, is caused by homeostatic imbalance as the endocrine systems fails to maintain a normal blood glucose level (Zoubina, 2014).
Type 1 diabetes:
Type 1 diabetes is a life-long autoimmune disease that is generally diagnosed during childhood (Jdrf.org.au, 2014). Type 1 diabetes is a result of autoaggressive T cells that infiltrate the pancreas and destroy insulin-producing β-cells (Betacellmetabolism.org, 2014). As a result the pancreas stops making insulin, and without insulin the body is unable to convert glucose into energy (Diabetesaustralia.com.au, 2014). Consequently, individuals with type 1 diabetes are at risk of a condition known as diabetic ketoacidosis (Diabetesaustralia.com.au, 2014). To counteract the lack of insulin, the body begins to burn fat and muscle as a substitute (Diabetesaustralia.com.au, 2014). This process results in the production of fatty acids called ketones, which are released by the liver to restore energy levels within the body (Drugs.com, 2014). If ketones accumulate in the bloodstream it causes a chemical imbalance (metabolic acidosis) (Chealth.canoe.ca,
Homeostasis is an organisms way of stabilizing and keeping a consistent internal environment within the body while our external environment is always changing. The endocrine system plays a big role in this as hormones help regulate the cells. The stimulus controls the release of hormones into the blood, it either increases or decreases the amount released. The receptor then detects the change, and sends the information to the control center. The control center then analyzes the information and decides the appropriate response. The effector then receives the information sent by the control center, the effector either puts out negative feedback or positive feedback. Negative feedback will shut off the stimulus, and positive feedback will fasten
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
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.
Type 1 diabetes is an autoimmune disorder, in which the pancreas does not produce insulin. It usually begins in childhood or adolescence. In Type 1 diabetes, the body’s immune system destroys beta cells in the pancreas that produce insulin. Insulin is a hormone that converts sugar, starches, and food into energy. Without insulin, blood glucose levels become too high, which is known as hyperglycemia. To prevent hyperglycemia, people with Type 1 diabetes must take insulin daily to survive. Genetic and environmental factors affect the onset of Type 1 diabetes. [1] According to the American Diabetes Association, a predisposition to Type 1 diabetes is
Homeostasis is described as the body's ability to maintain internally stable conditions. Each organ plays a huge role in maintaining this stability.
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.
Insulin is a hormone that is needed to allow sugar (glucose) to enter cells to produce energy. A more common form of diabetes is the type 2 diabetes. This condition develops in an individual when the body becomes resistant to insulin or doesn't produce the required amount of insulin. Type 1 DM can occur at any age. It is commonly found in children but this disease is also common among adults. Various factors contribute to an individual being diagnosed with type 1 diabetes, which may vary from genetics, exposure to certain viruses, lifestyle choices etc. Those with type 1 DM usually are not obese and initially show symptoms of diabetic ketoacidosis (DKA). These patients are dependent on exogenous insulin to counter low levels of
Diabetic ketoacidosis is an event which occurs when there is not enough insulin in the body to utilize sufficient amount of glucose needed to provide cells with energy; body then starts to use fatty acids as a fuel, which are converted to ketones in the liver. In healthy people who do not have diabetes, ketone bodies are produced in normal quantities and then successfully used by tissues as energy supply. This state is known as dietary ketosis and it is completely normal and may even provide health benefits. But in those who have diabetes, ketones are produced in enormous quantities and aren't used in full by cells, so they start to build up in the blood. Acids 3-hydroxybutyric acid and acetoacetic acid are produced rapidly causing decrease in buffering capacity of the blood and eventually depleting buffering systems (Manninen, 2004).
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.
For unknown reasons, the body of a T1D attacks the insulin producing cells, called islets, that are formed in the pancreas and destroys them. This type of attack is known as an autoimmune disorder (Diabetes Research Institute Foundation [DRIF], n.d.). Insulin is the hormone that allows sugar to enter cells, and produce energy. The body now sees islet cells as foreign and eventually the pancreas yields little to no islet cells. Once there are no more islet cells to produce the insulin hormone the sugar levels in the blood become high, called hyperglycemia. This disturbance in homeostasis is not like type 2 diabetes (T2D), where the body becomes insulin resistant. In a T2D, the pancreas still produces islet cells and they are still
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
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 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.
I think because of my history, people have attached the word resilient to me. I have had a professor and other social worker professionals wonder how I got to where I am when others similar to myself haven't done so well. The concepts above explain a lot and had I a better understanding of the above terms I might be able to explain how I was able to go in and out of modes or through necessity, be able to keep homeostasis without trying.
Homeostasis can have many different applications in everyday life. It can mean keeping the body in balance, in regards to weight, health etc. It can mean keeping the mind in balance, not sinking into a depression, not succumbing to harmful addictions, or not caving under everyday stress. I feel this term is very important, because developing balance, or homeostasis in my life was one of the main ways I battled and won depression. I plan on entering the field of counseling psychology, because of this I want to learn more about homeostasis.
