If there is a high level of glucose in the blood, the pancreas secretes

• insulin so the liver stores less glucose
• glucagon so the liver will break down glycogen to release glucose
• insulin so the cells can uptake glucose
• glucose to bring the level back up

A heavy 50 -year-old patient has increased thirst and is very fatigued (no energy).  The doctors tell the patient that their cells are resistant to insulin.  This patient most likely has

• Type II diabetes
• low blood glucose levels
• type I diabetes
• no glucose

A gland in your body releases hormone P.  This hormone causes target cells to release hormone J.  Once the body has enough hormone J, the gland stops the release of hormone P.  This is an example of

• a negative feedback loop
• a positive feedback loop
• a neutral feedback loop
• this is not a feedback loop

Patient 1's pancreas does not produce insulin but they take insulin shots and watch their diet in order to maintain normal blood glucose levels.  Patient 2 has consistently high blood glucose levels, but their pancreas is functioning normally.  Which is the best diagnosis?

• Patient 1 has type II diabetes and patient 2 has type I diabetes
• Both patients have type II diabetes
• Patient 1 has type 1 diabetes and patient 2 has type II diabetes
• Both patients have type I diabetes

When you are cold, your brain sends signals to release hormones to increase metabolic activity and generate heat.  When your body temperature returns to normal, the brain stops sending the signals.  This is an example of 

• a negative feedback loop
• a positive feedback loop
• a neutral feedback loop
• none of the above

If the body is lacking insulin, what else would happen?

• cells can't take up glucose
• lower glucose levels in the blood
• decreased thirst
• infrequent urination

Which of the following is MOST OFTEN involved in maintaining homeostasis?

• negative feedback
• positive feedback
• concentration gradients
• all of the above

In Type I diabetes the main problem with the body is that it....

• can't make insulin
• can't accept insulin
• can't produce glucagon
• can't absorb glucose

Insulin is released from the

• kidney
• pancreas
• pituitary gland
• stomach
