Hormonal Control - Coggle Diagram
Hormonal Control
Hormones
- Endocrine glands release hormones into the bloodstream
- Hormones act as chemical messengers carrying information from one area of the body to another
- The Endocrine system consists of several organs called Glands
- Hormonal control is slower than the nervous control
Decreasing Blood Glucose
- GLUCAGON is released in response to the decrease
- Glucagon travels to the liver to help covert glycogen to glucose
- A decrease by different receptors in the Pancreas
Insulin is released when you have High blood glucose
Glucagon is released when you have Low blood glucose
Blood Glucose
- Blood glucose concentration increases after eating carbohydrates
- Receptor cells in the Pancreas detect these increases
- Glucose levels are contolled to ensure there is suffeient glucose for respiration
Diabetes
- Diabetes is an example of a communication pathway that has failed
- Glucose concentration rises to dangerous levels
- Type 1) releases no insulin
- Type 2) is when insulin is not responded too
Target organ
- A hormone is specific this means it only affects cells in its target organ(s)
- Cells have receptor proteins on their membrane which only interacts with a specific hormone
Insulin
- Is released by the pancreas in response to increased blood glucose levels
- Insulin travels to the liver
- helps convert excess glucose to GLYCOGEN
- Glycogen is insoluble
- Glucose can lead to problems with Osmosis
