which of the following factors would cause an increase in the heart rate?
select all that
apply
epinephrine
parasympathetic stimulation
exercise
cold

Explanation:

• Epinephrine: It is a hormone that activates the sympathetic nervous system, increasing heart rate.
• Parasympathetic stimulation: This generally slows the heart rate, so it is not a factor for increase.
• Exercise: During exercise, the body needs more oxygen, so the heart rate increases to pump more blood.
• Cold: Cold can initially cause a slight increase in heart rate due to vasoconstriction (narrowing of blood vessels) which makes the heart work a bit harder, but it's not a major or consistent factor like epinephrine and exercise.

Answer:

Epinephrine, Exercise
