Absolutely. When you get your heart racing during (typically aerobic) exercise, you increase its ability to pump blood.
to much exercise can tire your body and can tensen up your muscles. for heart disease patients it can cause immense strain on the heart and increases the chances of heart attack.
The heart muscle can adapt to become more efficient to exercise. This allows it to push more blood per pump. It is able to take more stress as it adapts to it. Exercise for the heart also tends to be good for the rest of the body, especially the vascular system and lungs. To adequately work it, other muscles of the body need to do a lot of work and their fitness also increases.
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.
The more you exercise - the more oxygen your body's muscles need. In order for your heart to supply more oxygen - it must beat faster.
No you can do exercise when ever you want to improve muscles and other important part of your body.
exercise strenghtens all the muscles in the body. the heart is one. the harder you work, the harder the heart works to pumo blood around to other muscles and that makes it stronger. the heart pumps the blood with oxygen to the other muscles that need it
the body that needs exercise are the muscles in our body and our bones
Very basically the blood provides the body's working muscles with oxygen. During a work-out, the muscles are using up more oxygen than they would at rest. Various mechanisms transmit this information to the heart which increases the heart rate to push blood through the lungs around the body faster to get more oxygen to the muscles.

pumps them around your body to where they are most needed eg. if you are doing exercise then your heart will pump them to the muscles that are being used
== == it helps because it exercises your heart so it doesn't have to pump so much blood when you are exercise.
Running is cardiovascular exercise, because it increases the rate at which the heart pumps blood through your body to supply your muscles with oxygen during their contractions.
