- considered normal
A
functional murmur
5
Q
symptoms indicating activation of the Sympathetic division
A
- increased heart rate
- dilated pupils
- sweating

6
Q
- impulses travelling from SA node to AV node
- SA node-Bundle of HIS-Purkinje fibers
- a group of specialized cells that conduct electrical impulses in the heart

conducting cells to help determine heart rate
A
Sinoatrial (SA) nodes
8
Q
factors contributing to cardiac output
A
stroke volume x heart rate
9

heart parts contracting during systole and diastole
A
ventricles contract during systole, and atria contract during diastole
10
