After deoxygenated blood enters the heart at the right atrium, what path does it take?
Output from the heart can be altered mainly by changing which two variables?
Which portion of the heart would you expect to be the largest in a person with systemic high blood pressure?
What is the importance of the atrioventricular node's time delay upon receiving impulses from the sinoatrial node?
Which of the following structures is NOT part of the cardiac conducting system?
The sinoatrial node generates action potentials at a faster pace than normal heart rate. Why does the heart beat more slowly than the SA node would dictate?
