What does your heart do when your heart rate increase?
The heart rate increases because of your bodies cells need more oxygen during activity. Nerves in the heart make the pacemakers fire electrical impulses faster because they release epinephrine and neropinephrine and thus the heart rate increases.
What happence to your pulse rate when you exercise?
when you exercise, your heart rate increases. the more explosive and intense the exercise, the higher the rate will go. As with any muscle in the body, exercise makes it stronger. a stronger heart allows for more blood and oxygen to circulate with each pump resulting in your heart rate lowering not only during exercise but in daily life. a lower heart rate means your heart does not have to work as hard and thats a good thing !!!
Each time the heart beats what does it do to blood-?
It simply keeps it circulating throughout the body. Your heart is the one muscle that works all the time and keeps you alive. Your mind and your heart basically depend on each other. The mind tells the heart when to beat, and the heart pumps oxygen-rich blood to the mind. But really all the heart does is allow blood circulation through your body. Best to eat healthy to avoid disturbances in its work, which are usually lethal. (Life threatening.)
Each complete heart beat is called what?
