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.
Two hormones are responsible for controlling the concentration of glucose in the blood. These are insulin and glucagon. The diagram illustrates the principle of negative feedback control in action involving blood/sugar levels.ancreas Receptors. The receptors of the pancreas are responsible for monitoring glucose levels in the blood, since it is important in every cell for respiration. Two types of cell release two different hormones from the pancreas, insulin and glucagon.
