Out in the open atmosphere, there is enough motion in the air to keep the oxygen and carbon dioxide mixed up. This motion of the air mostly comes from convection currents (i.e. wind) caused by temperature differences.
For homeostasis, insulin is the main hormone involved. Blood sugar regulation is the process by which the levels of blood sugar, primarily glucose, are maintained by the body.here are also several other causes for an increase in blood sugar levels. Among them are the 'stress' hormones such as epinephrine (also known as adrenaline), several of the steroids, infections, trauma, and of course, the ingestion of food.
Glucose Homeostasis and Starvation. Glucose Homeostasis: the balance of insulin and glucagon to maintain blood glucose. Insulin: secreted by the pancreas in response to elevated blood glucose following a meal.Insulin lowers blood glucose by increasing glucose uptake in muscle and adipose tissue and by promoting glycolysis and glycogenesis in liver and muscle.nsulin: secreted by the pancreas in response to elevated blood glucose following a meal.
