Homeostasis is the biological process that maintains a stable internal environment despite what occurs in the external environment. Chemicals and bodily functions are maintained in a balanced state so the body may function optimally. There are various systems in the human body that require maintenance through the processes of biochemical checks and balances so they may function properly. One of these systems includes the rise and fall of blood glucose and is under the control of the homeostatic regulation process. Homeostasis is essential in blood glucose regulation as high blood glucose levels (hyperglycaemia) and low blood glucose levels (hypoglycaemia) are dangerous and can affect the human body in many ways and can also lead to fatal events. Therefore, it is important that glucose enters and leaves the blood at equal rates in order to keep blood glucose levels within the normal, healthy range of 70 mg/dl to 110 mg/dl. A number of hormones regulate the balance between these processes and are secreted by the adrenal glands and pancreas.

Homeostatic System of Blood Glucose Regulation
The human body requires homeostasis to keep a set point at a constant. With feedback loops, the internal environment of the body can achieve to keep it at the set point. All homeostatic mechanisms use a feedback loop to inform the body about any changes that occur externally or internally. There are two different kinds of homeostatic mechanisms: a positive feedback mechanism and a negative feedback mechanism. Positive feedback mechanisms boost the physiological process and amplify the system 's action to move the system away from the equilibrium state so it is more stable. Negative feedback mechanisms, on the other hand, maintain equili...

Individuals who are diagnosed with Type 1 Diabetes must be treated with daily injections of insulin into their body after meals along with a managed diet and regular exercise so they can keep a balance between their energy needs and so they can maintain a storage of glucose for emergencies.
To produce insulin for diagnosed patients scientists use a process called 'genetic engineering '. Genetic engineering uses various technologies to switch the cells genetic makeup in order to develop an organism. One advantage of genetic engineering is that the insulin produced is identical to human insulin but isn 't made by humans but by bacteria itself.
Diabetes medication such as insulin can overshoot the amount of insulin that is required by the body to keep homeostasis, which then causes the blood glucose level to go too low and become hypoglycaemic.

Maintaining a Stable Internal Environment Essay

- INTRODUCTION Maintaining a stable internal environment, or homeostasis, is essential for the survival of complex animals. Living organisms must maintain a salt and water balance, and they must continually remove the toxic by-products generated by metabolism. Organisms have evolved a variety of strategies to maintain a more or less stable internal environment. In animals that have a circulatory system, the blood typically passes through excretory organs, commonly termed kidneys. In terrestrial animals, the kidneys not only play a major role in the removal of wastes, but are also the primary organs of osmoregulation....   [tags: Biology]

Physiological Processes And Its Effect On A Stable Internal Environment Essay example

- 1. A. Homeostasis is the ability for the body to maintain a stable internal environment, despite changes that can occur in external conditions. A typical feedback loops has three main components that make it function. 1) Receptor, which regulates changes in a controlled environment and sends information to the control center. 2) Control Center, which compares incoming input with other information and informs the effector, for a change to occur. 3) Effector, acts on the changes and releases the response....   [tags: Neuron, Nervous system, Action potential]

What is Homeostasis? Essay

- What is Homeostasis. Homeostasis is the ability to maintain a reasonably stable internal environment that is necessary for overall function and survival of living organisms. Homeostasis is able to maintain the function of an organism by constantly adjusting to the change in conditions caused by external and internal stimuli, stabilising internal conditions suitable for survival. In humans it is carried out by the whole body, reaching every cell and organ, the body being able to detect changes in internal conditions and perform certain adjustments to account for the changes....   [tags: control system, blood glucose]

Stability of Humans' Internal Environment Maintained by Homeostasis Essay

- Homeostasis is the process of a system in which variables are regulated so that internal conditions remain stable and moderately constant. In response to both internal and external changes to conditions, homeostasis is a process that maintains the stability of the human’s internal environment. To regulate changes in the condition, homeostasis requires a sensor to detect changes, an effector which ultimately varies that condition and a negative feedback connection between the two. Homeostasis therefore ultimately stabilizes health and functioning....   [tags: body, blood, organism]

Creating Homeostasis for the Human Body Essay

- The human body has 11 different organ systems working together to perform functions for life. The circulatory system is one, which consists of the heart, the blood vessels, and the blood that circulates though them. This system is an important part of supplying the needs of cells by transporting nutrients and oxygen to tissues and organs in the body and removing substances such as waste products from the body. The lymphatic system, another body system, consists of a network of lymphatic vessels throughout the body, lymph nodes, the thymus gland, tonsils, adenoids, and spleen....   [tags: Health]

- The Significance of Homeostasis to the Human Body What is homeostasis. According to the 'Oxford Colour Medical Dictionary, Third Edition' homeostasis is the "the physiological process by which the internal systems of the body (e.g. blood pressure, body temperature, acid-base balance) are maintained at equilibrium, despite variations in the external conditions" Homeostasis is the maintenance of a stable internal environment within tolerance limits, this is the restricted range of conditions where cellular operations effectively work at a consistent rate and maintain life....   [tags: Papers]

- Section one Homeostasis, which literally means ‘same standing’ from the Greek words for "same" and "steady," refers to any process that living things use to actively maintain fairly stable conditions necessary for survival (Clancy et al., 2011). It is a term introduced by Cannon in 1930 to describe the goal of all the body’s physiological processes. These processes dynamically maintain a relatively constant state called steady-state in the internal environment (CREDO, 2006). The internal environment is the fluid that surrounds cells, which refers to the direct cell survival and material exchange with the environment....   [tags: homeostasis, endocrine system]

Homeostasis Essay

- Elaine’s reaction to the high winds and extreme cold is because of her body maintaining homeostasis. Homeostasis is the ability of the human body to maintain its internal environment at equilibrium, or in other terms, to keep the body at a constant temperature. This ability is regulated by the circulatory systems, endocrine systems, and the nervous system, because of how they organize the various functions in the human body’s system. When the body maintains homeostasis, it controls blood pressure, body temperature, pH, and glucose concentration....   [tags: equilibrium, thermoreceptors, diagnostics]

- Homeostasis Homeostasis works to maintain the organism's internal environment, where the body's processes are able to function at a level that would allow life to continue in that organism. The three systems which are controlled by homeostasis are the respiratory, cardiovascular, and muscular systems. Changes to the cardiovascular system are often a result of changes in the activities of other systems.
