Very probable any serious effect.
Exercise increases the heart rate, because the blood has to supply additional oxygen to the muscles.
Coronary artery disease limits the ability of the heart muscle to get the oxygen and nutrients it needs. This can decrease the efficiency of the heart muscle.
Running increases the body's need for oxygen. The heart rate speeds up to deliver more oxygen to the body. The pulse increases.
Yes, the heart rate is pumping harder to get oxygen to the muscles in your body.
== == it helps because it exercises your heart so it doesn't have to pump so much blood when you are exercise.
When you exercise, certain muscles need more oxygen. Your body does this by bringing more oxygenated blood to those muscles. This is done by an increase of heart rate.
When the heart beats too rapidly, it pumps less efficiently and blood flow to the rest of the body, including the heart itself is reduced. The higher-than-normal heartbeat means there is an increase in demand for oxygen by the myocardium (heart muscle) - if this persists it can lead to myocardial infarction (heart attack), caused by the dying off of oxygen-starved myocardial cells.
It is the heart that pumps fresh oxygen in the blood.
well, the answer is so simple, a frog's heart needs oxygen which is required from the lungs therefore the circulatory system (blood/heart) needs oxygen from the respiratory system (lungs). since they are so close together, both system have easy access to one another.
blood coming from the HEART is rich in oxygen
the heart race is effect on the
Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
