Multiple Choice

Where does the electrical current in the heart start?

• The ventricle

• The apex

• The sinoatrial node

• The coronary artery

Multiple Choice

Systole is...

• the word used to describe the heart and its functions

• when the heart contracts, the blood is forced out of the heart

• the name of the blood leaving the body

• Carry deoxygenated blood and waste away from body cells and to the heart

• Take oxygenated blood to the heart

• Maintain oxygen levels in blood
