Answer explanation

Match the following terms with their definitions.

• Systole

• ventricle relaxing & filling blood

• Diastole

• amount of blood pumped by ventricle per contraction

• Cardiac Output

• volume of blood each ventricle pumps per min (mL/min)

• Stroke Volume

• ventricle contracting & pumping blood

• Heart Rate

• amount of heart beats per min

Match the following terms with their definitions.

• Purkinje Fibers

• measure of electrical activity produced by SA & AV nodes

• Cardiac Cycle

• nerves extending from bundles branches (up heart walls)

• ECG/EKG

• complete cycle of blood filling and pumping

• Bundle Branches

• nerves extending from NA node (down septum)

Answer explanation

Draw an arrow showing how blood circulates through the heart. Use blue for deoxygenated and red for oxygenated.

Answer explanation

Place the way blood flows through the heart starting from the vena cava & ending with the aorta.

Begin on the top left corner and work your way down, then up, and back down.
