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.
1. The negative feedback system has three main components that enable the system to work.
• The stimulus produces a change in the variable; sometimes the stimulus disrupts homeostasis by increasing or decreasing the controlled condition.
• The change is detected by the receptor (eyes, ears, touch etc.) via the stimuli

Diabetes mellitus is the failure to have control over blood glucose levels. When the system that controls the insulin and glucagon is disrupted, diabetes mellitus is the result. The occurrence of diabetes mellitus is due to excessive blood sugar (hyperglycemia).
There are two types of diabetes mellitus
Type 1: In type 1 diabetes the cells that produce insulin in the pancreas are destroyed and cannot be made, this type of diabetes usually occurs in childhood due to the autoimmune system attacking and destroying its own cells that produce the insulin, the beta cells in the islet of Langerhans are destroyed and thus unable to produce insulin. This type of diabetes in incurable and is treated with insulin injections.
Type 2: In type 2 diabetes, the pancreas produces insulin, however the body doesn’t respond to it as it should, this is because the quantities of the insulin being produced are insufficient, or the body’s cells just don’t react to it and so the glucose levels in the system remain high. Type 2 diabetes is a ‘progressive disease’ and can get worse if it is not managed properly. Long term effects of high blood sugar can result in heart disease or kidney
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 is carried out in two ways: Negative feedback and Positive feedback. In a feedback loop the product of a process, has an effect on
Type 1 is characterized by the body’s inability to produce insulin. It is caused by autoimmune-mediated destruction of pancreatic beta cells, which are responsible for producing insulin. There appears to be a hereditary link in people with Type 1 diabetes. Other factors have been known to cause Type 1 diabetes such as viral infections, toxins, and other environmental factors. Type 1 diabetes is the rare form, affecting about 10% of the diabetes population. Its onset usually occurs in people less than the age of 20.
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 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
Diabetes Mellitus is currently classified as type one and type two. Type one diabetes is characterized as a complete lack of insulin due to the destruction of the pancreatic cells. Type one is thought to come from an interaction between a genetic component or an acquired environmental component (auto immune). Type one diabetes, develops over the course of years. The peak age for diabetes is ten to fourteen years. With beta cells destruction happening before the disease is diagnosed.
Type 1 diabetes is a disease where the pancreas no longer produces insulin for the body function properly and survive. When your body is no longer producing insulin, you will need a way to provide your body with insulin to function properly and to survive. Type 1 Diabetes in children is commonly known as juvenile diabetes or insulin-dependent diabetes.
Firstly, those who have Type 1 diabetes; do not produce any insulin. Type 1 diabetics experience broken down fat and have high ketone levels, which destroys the insulin produced by beta cells located in the pancreas.Symptom development depends on the number of beta cells that are destroyed. Type 1 can also be caused by genetic factors, also it is believed that diabetes can be caused from environmental factors. However, type 2 diabetes occurs when insufficient amounts of insulin are produced. Alos, it supplies some insulin, but not enough to maintain healthy blood glucose levels. Typically, this particular type of diabetes occurs in the mid-forties, and there is a genetic factor, over three-quarters are overweight. Diabetes can be regulated by exercise, diet, weight loss, and oral medications to lower blood glucose levels. Millions of people have diabetes and are not aware of it, that is why it is important, to become familiar with symptoms of this disease and its risk
Type 1 diabetes, also referred to as Insulin Dependent Diabetes Mellitus (IDDM) or Juvenile Diabetes, can be caused by a genetic disorder. It can occur at any age, but it is most often diagnosed in children, adolescents, or young adults around 20 years old or before a person is 30 years of age. Insulin is a hormone produced by special cells, called the beta cells, in the pancreas, an organ located in the area behind the stomach. Insulin is needed to move blood sugar (glucose) into cells, where it is stored and later used for energy. In type 1 diabetes, these cells produce little or no insulin. Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. The body is unable to
The body can regulate its internal environment through feedback systems. A feedback system is a cycle of events in which the condition of the body is monitored, changed, re-monitored and re-evaluated. Each monitored variable such as temperature, blood glucose and blood pressure is termed as a controlled condition. Any disruption that changes a controlled condition is called a stimulus. Only three components make up the feed back system - a receptor, a control center and an effecter.
Type 1 Diabetes mellitus is characterised by the genetic or autoimmune destruction or deficiency of the pancreatic b cells that produce insulin and usually progresses rapidly that it is often diagnosed in childhood. Individuals diagnosed with Type 1 diabetes, present with signs of pancreatic b-cell destruction prior to diagnosis (Armstrong 2014).
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 uses a feedback mechanism called negative feedback meaning that it works from feedback it receives about changes that need to be made. The mechanism responds to the normal range of environmental factors because the receptors sense that a change needs to be
First I would like to start out with clarifying the different kinds of homeostasis in greater detail.
