Explain the probable homeostatic responses to changes in the internal environment following the consumption of a healthy meal.

Homeostasis:

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 which include sensors, signal transmissions, control centres and also effectors.  The above allow the body to adapt to its own environment and therefore allows it to function normally.

The reason that we need the internal environment within the body to stay constant is because the enzymes within our body can only work effectively within a certain ph and temperature, if these conditions are not maintained the enzymes will not be able to work and therefore the chemical proteins within the enzymes will not be able to speed up reactions within the body and the enzymes will become denatured, if this occurs this occurs the consequences could be fatal for the individual.

Homeostatic mechanisms work by negative feedback as they detect any changes in the boys internal environment and bring about an effect that will reverse the change.

 Although after eating a meal certain changes occur within the body they are:

After eating a healthy balanced meal the glucose levels within the blood will rise the reason for this is because the food in which you have just eating contains glucose, therefore the islets of langerhans within the pancreas release insulin to reverse the change.  The islets of langerhans contain a small number of alpha cells and numerous beta cells, the alpha cells secrete glucagon where as the beta cells secrete insulin, this has an antagonistic effect on the blood glucose level within the body.

4 stars This essay explains the principles of homeostasis with reference to maintaining blood glucose levels. It is set out logAically, with mostly good content linking to the roles of the pancreas and liver, alongside insulin and glucagon. Areas for improvement, or extension of knowledge and understanding, have been identified within the marking comments. There is some content towards the second half of the essay which is not required in order to meet the essay title.
