Write a teleological explanation for why heart rate increases during exercise. Now write a mechanistic explanation for the same phenomenon.

What will be an ideal response?


Teleological: Heart rate increases because the increased activity of skeletal and cardiac muscles requires increased delivery of blood contents such as oxygen and glucose. Mechanistic: Heart rate increases in response to signals from the brain (pacemaker cells of the heart are stimulated by the nervous system).
