What is the normal level of glucose in the blood? Why is this called a "set point"?

90mg/100mg, because it's the point at which you blood sugar is at balance and starts at.

What is the effect of glucagon? What cells release glucagon?

causes the liver to breakdown glycogen into glucose, Pancreatic alpha cells

What is the effect of insulin? What cells release insulin?

causes your liver to take up the glucose and store it as glycogen; causes body cells to take up glucose, pancreatic beta cells

Where does the glucose that is released into the blood ultimately end up (2 places)?

liver and body cells

What would you expect to happen if your blood sugar was 120 mg /100 mL ? Be specific.

pancreatic beta cells would release insulin into the blood that would cause the liver and body cells to take in the glucose. Blood glucose level will decline.

The image shows two different types of stimuli (1 and 2), but doesn't explain what the stimuli is that causes blood sugar to raise or lower. Based on clues in the graphic, what are the two stimuli?

raise- eating lower- time passing without eating

In a single sentence, explain the relationship between the pancreas and homeostasis.

the pancreas help the body maintain homeostasis by releasing the hormones insulin and glucogan in order to returen the blood glucose level at it's set point

A person with diabetes cannot regulate their blood sugar, mainly because the pancreas does not release enough insulin. To treat the disease, a person must monitor their blood sugar, if their blood sugar is high, they must take an injection of insulin. How do you think they would need to treat low blood sugar?

they would need to eat something to take an injection/pill of glucogon

What happens when your blood sugar rises?

your pancreatic beta cells release insulin into the blood
