When you are hot, your body sweats to cool you down. This means your temperature went above normal and your body sweats to counteract that change to bring you back to normal. What kind of feedback loop would this be?
A. Negative Feedback Loop
B. Positive Feedback Loop
C. Neutral Feedback Loop
D. Linear Feedback Loop
Homeostasis
A. allows for a wildly fluctuating internal environment
B. is impossible in vertebrates
C. is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation
D. is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation
What is the main function of the endocrine system?
A. It creates chemicals, or hormones, that are sent around the body to maintain homeostasis.
B. It creates electrical messages that are sent around the body to maintain homeostasis.
C. It maintains the correct level of oxygen in the body to maintain homeostasis.
D. All of above
Detects change and sends a message to the control center
A. receptor
B. control center
C. effector
D. regulation
Which one here reduces the amount of glucose in the blood?
A. Glucagon
B. Insulin
C. Glycogen
D. ADH
When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels.
