What does a pace maker adjust the heart rate to correspond with in the body?
it adjusts the heart rate to correspond to the body's need for oxygen
What cell set the pace for the beating for the heart as a whole?
Purkinje fibers
What is the name of rate set by the heart's pacmaker?
Sinus rhythm
What is the difference between a resting heart rate and a active heart rate?
The difference between a person's resting and target heart rate reflects the amount of work the heart must do to meet the increased demands of the body when exercising.
How does depressants affect the heart rate?

Does the SA node set the pace for the whole heart?

When you are swimming how fast does your heart beat?
when sprinting (putting in as much effort as possible) your heart rate will reach around 200bpm (beats per minute). Swimming at an average pace your heart rate will be around 150-160 bpm and at a slow easy leisurely pace your heart rate will be around 120-140 bpm. Heart rates will vary for different people and in general the younger you are, the higher your heart rate will be and the fitter you are, the lower your heart rate will be.
How is the pace maker involved in your heart beat?
The pace maker uses electrical impulses to regulate heart rate. It is used when the bodies own impulses from the brain are not able to do the job anymore.
3 pacemaker sites within the heart and rate that each of these sites will pace?

How does adrenline effect heart rate?
Adrenaline acts on the Beta-1 adrenoceptors on the heart muscle to increase the heart rate and the force of the contraction. Leading to more blood being pumped around the body at a higher pace.
What cell set the pace for the beating for the heart as a whole?
Purkinje fibers
How do sympathetic and parasympathetic nerves affect a pacemaker?
Sympathetic nerves increase the heart rate by releasing norepinephrine, while parasympathetic nerves decrease the heart rate by releasing acetylcholine. This affects the pacemaker by altering its firing rate and influencing overall heart rhythm.
How the human heart could compensate for flow rate changes to maintain blood pressure?
The human heart could compensate for flow rate changes to maintain blood pressure by setting the pace at which it beats and maintains blood flow. When a heart rate increases, blood pressure will rise, and when a heart rate decreases, blood pressure will drop.
What tools can specifically maintain your heart rate count for running exercises?
You can maintain your desired heart rate by wearing a heart rate monitor. These are small electronic devices that usually resemble a wrist watch. The heart rate monitor will display your current heart rate and allow you the opportunity to either speed up or slow down your running pace in order to stay within what your desired heart rate is. If you notice your heart rate is getting higher than desired, slow down, and if it is lower than desired, speed up.
What is the name of rate set by the heart's pacmaker?
Sinus rhythm
How the heart respond to the strenuous exercise?
when you exercise, the heart rate increases, (as does your breathing pace), so that more oxygen can be carried in the blood to your muscles. The more intense the exercise, the more your muscles have to work, so more oxygen is required and your heart rate will increase. The quicker you heart rate returns to normal, the better your fitness.
