Blood Glucose Levels

The insulin changed the plasma glucose levels by raising dramatically from fasting to the one hour mark, but by hour 3 it droped again to almost the same levels as fasting. The glucagon remained almost the same on throughout the levels except that it lowered a bit 1 hour after the meal.

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.

unit 5 P5- Explain the concept homeostasis with reference to the control of heart rate, breathing rate, body temperature and blood glucose.

The blood glucose level has very limited range for humans to survive and stay healthy. Generally, people are able to remove excess glucose rapidly from the body but this is not the case when they are diagnosed with diabetes and insulin resistant situations. The lack of insulin resistance can also lead to a decrease in glycogen synthesis and storage as it usually converts glucose to energy for cell’s use (Jensen & et al. 2011). When insulin is produced under insulin resistance, the cells are incapable of using them effectively which then leads to high blood sugar level as ketones and ketoacids are produced as an alternative energy source for the body. The rise of ketoacid causes the blood pH acidic and the patient may also be diagnosed with ketoacidosis (Newton & Raskin 2004). There would also be less intake of lipid and more of stored triglycerides as the lipids are effected by the insulin. As the glucose levels increase, the muscle glucose uptake will decrease while the liver glucose production and blood fatty acid concentration will also increase within the body (Lichtenstein & Schwab 2000). Excess glucose within the blood are converted to fat which can lead to Diabetic Dyslipidaemia and furthermore to obesity, hypertension and

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.

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.

The stimulus produces a change in the variable; sometimes the stimulus disrupts homeostasis by increasing or decreasing the controlled condition.

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 maintains a stable environment inside the body like the balance of sugar. The food that we digest is broken down into Glucose which is a simple sugar. Glucose is carried to every cell in the body by the blood stream to be used as energy for the body. The stored form of Glucose which is Glycogen which is a group of Glucose connected.

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 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.

1. a) The three basic components of feedback system are receptor, integrating center and effector. For the feed back to work, the body will feel stimuli in its environment causing the receptor to act on that change. The receptor monitors the change and send a signal through the afferent pathway an inputting the information into the integrating central. The Integrating center, usually the brain evaluates the input from the receptor and output the command through the efferent pathway. Effector, generally it will be a gland or muscle receives the command and act upon authority to the set point. There are two basic types of communication negative feedback and positive feedback. Most homeostasis is negative feedback the effector will reverse the change returning the body to a normal state. Positive feedback, reinforce the change in the effector driving it in the direction of completion.
