Document Summary
An easier way to think of the cardiovascular system is as a set of closed tubes (blood vessels) which are lled with uid (blood) that is moved around by a central pump (the heart). There are really two separate circulation circuits : pulmonary circulation: this circuit delivers blood to the lungs for it to get rid of carbon dioxide and pick up a fresh supply of oxygen (more on this in module 10). Once it passes through the tissues (picking up some carbon dioxide in exchange for delivering oxygen), it returns to the right side of the heart. If our resting heart beat is 70 beats per minute, and there are 60 minutes in an hour (70 x 60) and 24 hours in a day (x 24); that is equal to. That is a lot of work: the heart structure: You should know the basic structure of the heart.
