Match the following terms with their definitions.

• Heart Rate

• amount of blood pumped by ventricle per contraction

• Diastole

• ventricle relaxing & filling blood

• Stroke Volume

• ventricle contracting & pumping blood

• Cardiac Output

• amount of heart beats per min

• Systole

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

Match the following terms with their definitions.

• Purkinje Fibers

• nerves extending from bundles branches (up heart walls)

• Bundle Branches

• measure of electrical activity produced by SA & AV nodes

• Cardiac Cycle

• nerves extending from NA node (down septum)

• ECG/EKG

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.
