because the glucagon will bind to receptors in the liver starting the response. The glucose will then enter the blood stream thus increasing the blood glucose concentration. This will be detected by the pancreas which will then stop or decrease the secretion of glucagon; this is the negative feedback as now the internal environment has returned to the norm. The ability of humans being able to control the blood glucose levels is a benefit because many biological and chemical processes in the body need

A negative loop could be hormone secretion. Hormone levels decrease so the body stimulates the organ to produce more. At a certain level‚ the body recognizes that there is too much and pulls back production the negative

Biology exam Endocrine system: Hormones: chemical messengers that coordinate the body’s activates. Substances secreted by cells that act to regulate the activity of other cells in the body. They are part of the endocrine system and they are slow acting but have a longer affect than neurotransmitters. Functions: * regulate growth‚ development‚ behavior‚ and reproduction. * Maintain homeostasis * Regulate metabolism and water and mineral balance * Respond to external stimuli

Patients diagnosed with GBS start off with a febrile episode‚ followed by muscle weakness‚ ascending paralyzation‚ and increased oral secretions. A patient can be diagnosed better by various testing such as measuring the patient’s Negative inspiratory force‚ blood gasses and vital capacity. The management of GBS is fairly easy but very tedious‚ the diagnostic numbers must be constantly updated
