Today in class we:
Discussed the electrical and mechanical conductions of the heart:
- Electrical impulses conducted through specialized tissues or nodes from SA node through the AV node, Bundle of His, Left and Right Bundle branches, Purkinje fibers
- Mechanical contraction of the heart, or cardiac cycle, is produced from alternating systole and diastole contractions of the atria and ventricles. This rhythms are influenced by electrical impulses and changes in chamber pressure.
Homework: due Tuesday
