Answer explanation

Match the following terms with their definitions.

• Heart Rate

• ventricle contracting & pumping blood

• Systole

• amount of blood pumped by ventricle per contraction

• Stroke Volume

• amount of heart beats per min

• Cardiac Output

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

• Diastole

• ventricle relaxing & filling blood

Match the following terms with their definitions.

• Cardiac Cycle

• nerves extending from bundles branches (up heart walls)

• Bundle Branches

• measure of electrical activity produced by SA & AV nodes

• ECG/EKG

• nerves extending from NA node (down septum)

• Purkinje Fibers

• complete cycle of blood filling and pumping

Compare arteries and veins.

Groups:

(a) Artery

,

(b) Vein

• Thicker Smooth Muscle & Connective Tissue

• No Valves

• Thinner Endothelium

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.
