Questions & Step-by-Step Solutions
Which of the following factors primarily influences heart rate?
Step 1: Understand what heart rate is. Heart rate is the number of times your heart beats in a minute.
Step 2: Learn about the nervous system. The nervous system controls many body functions, including heart rate.
Step 3: Identify the two parts of the nervous system that affect heart rate: the sympathetic nervous system and the parasympathetic nervous system.
Step 4: Know that the sympathetic nervous system is responsible for the 'fight or flight' response, which increases heart rate during stress or exercise.
Step 5: Recognize that when you are relaxed, the parasympathetic nervous system can slow down your heart rate.
