Answer explanation

Match the following terms with their definitions.

• Stroke Volume

• ventricle relaxing & filling blood

• Cardiac Output

• amount of heart beats per min

• Heart Rate

• ventricle contracting & pumping blood

• Systole

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

• Diastole

• amount of blood pumped by ventricle per contraction

Match the following terms with their definitions.

• Cardiac Cycle

• nerves extending from NA node (down septum)

• Purkinje Fibers

• measure of electrical activity produced by SA & AV nodes

• Bundle Branches

• complete cycle of blood filling and pumping

• ECG/EKG

• 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.
