Homeostasis: Balance Of Sugar Levels In The Body

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.

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 described as the body's ability to maintain internally stable conditions. Each organ plays a huge role in maintaining this stability.

Homeostasis is when the body has a stable internal environment. Homeostasis is important, it keeps the body balanced in order to function. Since the body can function only under certain conditions, without homeostasis this wouldn’t be possible.

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.

An organ called the pancreas makes insulin. The role of insulin is to move glucose from the bloodstream into muscle, fat, and liver cells, where it can be used as fuel.

Two of the main pancreatic hormones are insulin, which acts to lower blood sugar, and glucagon, which acts to raise blood sugar. Maintaining proper blood sugar levels is crucial to the functioning of key organs including the brain, liver, and kidneys. (Columbia, 2015)

Homeostasis is a self-regulating process of equilibrium where the internal conditions of an environment are kept constant to maintain its normal functions. Homeostasis exists to primarily help your body control body temperatures and fluids at stable levels. If homeostasis cannot be sustained within limitations, our body cannot function properly.

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.

One point where there is a constant risk of losing glucose is in the kidney but normally the kidney will reabsorb glucose that has spilled into the urine. Unfortunately when blood glucose gets above 20mM then it can’t be reabsorbed so the glucose is lost so its better to keep blood glucose low to avoid this loss. We need glucose all the time but we cant eat all the time so we need a system for storing glucose. So what is happening when blood glucose levels fall after a meal is we are storing the glucose so that we can use it later. The main place we store glucose is in the liver and we can store enough to keep us going for 2-3 days. Smaller amounts are taken into muscle ad fat cells stored. This is stimulated by insulin and is the way blood glucose levels are kept low. One of the livers roles is to be a ‘rechargeable glucose

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.

The main function of the pancreas is maintaining blood glucose levels to about 70-150 milligrams per decilitre. The pancreas does this by measuring if the blood sugar level is too high or low, if it is not the correct level then a hormone is released. If the blood sugar level is too high insulin is released from the beta cells and causes glucose to enter body cells to be used for energy but sometimes can stimulate glucose to turn to glycogen in the liver. However, if it is too low then glucogen is released into the blood which causes the stored glycogen in the liver to break down

The control of glucose levels in the blood is an example of homeostasis. Homeostasis is the body maintaining a stable internal state despite changes in the external environment. This homeostasis is achieved through negative feedback. Negative feedback is when a deviation of normal levels is brought back to the normal level by a corrective response. The larger the deviation from the normal, the greater the corrective response will be. The level of glucose in the blood achieves homeostasis by its removal from the blood being balanced with its entry into the blood.
