Describe the different diabetes? |
Diabetes is when people can't control blood sugar levels. Type 1-pancreas don't produce insulin...to control you need to exercise and inject insulin. Type 2-insulin is released by pancreas but body doesn't react to it. |

|
|
Define homeostatis? |
Maintaining a stable internal enviroment. |
Body enviroment |
|
|
What is the affect of carbon monoxide on the function of blood? |
Combines with haemoglobinin red blood cells. This reduses the ability of blood to carry oxygen putting stran on the circulirity system. Increases risk of contary heart disease and strokes. |

|
|
What happens when blood sugar levels are too high? |
Pancreas release hormone called insulin. Insulin transports in blood to liver. Insulin causesliver cells to take out glucose from blood and convert it into glycogen. It can convert back when required. |
Glycogen |

What is a hormone? |
A regulatory substance produced in an orgasm and trasported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action. |

|
When blood sugar levels are to low? |
Glycagon is releaed by pancreas into liver converting glucagen back to glucose which is then released into the blood. |
Glycagon |
|
|
What happens when your to hot? |
Sweat Vasodilation-when blood vessels become wider allowing more blood and heat to be lost. |
Vasodilation |

|
What happens when your to cold? |
Shiver Hair stands up Vasconstriction-blood vessels get narrower letting less blood flow through skin and conserving heat in body. |
Vasconstriction |
|
|
How do scientist classify veterbrates into different groups? |
Depending on thier features How it takes in oxygen..lungs, gills, skin Thermoregulation..how it maintains body temp Reproduction..viviporous or oviporous |
Thermoregulation |
|
