Question 18

The axial portion of the body consists of:

Answer 18

head, neck, and torso or trunk

Question 19

Why is homeostasis also called “balance” of body function?

Answer 19

Homeostasis is what physiologists call the relative constancy of the internal environment.

*conditions stay within a narrow range. The temperature, salt content, acid level (pH), fluid volume and pressure, oxygen concentration, and other vital conditions must remain within acceptable limits

Question 20

What is a feedback loop and how does it work?

Answer 20

Feedback control
To accomplish such self-regulation, a highly complex and integrated communication control system is required. The basic type of control system in the body is called a feedback loop.

Question 21

Discuss/Explain:
Negative feedback

Answer 21

negative feedback loops because they oppose, or negate, a change in a controlled condition
(Reactionary)

Question 22

Discuss/explain: (uncommon)
positive feedback loops

Answer 22

Positive feedback control loops are stimulatory. Instead of opposing a change in the internal environment and causing a “return to normal,” positive feedback loops temporarily amplify the change that is occurring. This type of feedback loop causes an ever-increasing rate of events to occur until something stops the process

*example labour contractions

Question 23

the activity of blood cells called platelets, which become increasingly sticky in response to damage to a blood vessel.
Circulating platelets rapidly cling to the damaged area and release chemicals that attract additional platelets which accumulate at the site of damage to form a blood clot.

This is an example of what kind of feedback?

Answer 23

positive feedback regulation

Question 24

Parts of a Feedback loop (3)

Answer 24

Feedback loops involve a sensor, a control center, and an effector

Question 25

Can negative feedback turn into positive feedback?

Answer 25

Negative feedback loops can turn into positive feedback loops during injury or disease, possibly causing a deadly shift in body function
