Answer explanation

Match the following terms with their definitions.

• Diastole

• amount of blood pumped by ventricle per contraction

• Systole

• amount of heart beats per min

• Stroke Volume

• ventricle relaxing & filling blood

• Cardiac Output

• ventricle contracting & pumping blood

• Heart Rate

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

Match the following terms with their definitions.

• Bundle Branches

• nerves extending from NA node (down septum)

• ECG/EKG

• complete cycle of blood filling and pumping

• Purkinje Fibers

• measure of electrical activity produced by SA & AV nodes

• Cardiac Cycle

• nerves extending from bundles branches (up heart walls)

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.
