Question 3 - 10 What is homeostasis?

Answer 3 – 10 The body’s ability to maintain a relatively stable internal environment.

Question 3 - 20 In response to rising blood sugar, the brain stimulates the pancreas to release insulin – which lowers blood sugar. This represents ___________ feedback.

Answer 3 – 20 Negative feedback

Question 3 - 30 An example of positive feedback is:

Answer 3 – 30 Blood clotting, ovulation, child birth

Question 3 - 40 IN THE FEEDBACK SYSTEM CONCERNING RISING BLOOD SUGAR, THE PANCREAS (WHICH RELEASES INSULIN TO LOWER IT), REPRESENTS THE:

Answer 3 – 40 EFFECTOR

Question 3 - 50 BRIEFLY DESCRIBE A FEEDBACK SYSTEM AND INDICATE THE: RECEPTOR CONTROL CENTER EFFECTOR

Answer 3 – 50 Some stimulus disrupts homeostasis and your blood pressure changes (increases or decreases) Receptors in the blood vessels sense the altered blood pressure (these receptors are called baroreceptors because they are pressure-sensitive) and they… Send nerve impulses called input to the brain… The brain acts as a control center which evaluates the input and sends… Output in the form of nerve impulses to your heart and blood vessels… Your heart and blood vessels are the effectors which cause a change in your heart rate and blood vessels which… Reverses the original stimulus and brings your blood pressure back to normal to maintain HOMEOSTASIS!
