• Keeps food and oxygen moving throughout body

• Blood

• Directional flow of food and oxygen

• 
• 
• Inefficient (1)

• Keeps digested food near tissues

• 
• Requires lots of energy & many complicated tubes

Answer explanation

Match the following terms with their definitions.

• Stroke Volume

• ventricle relaxing & filling blood

• Diastole

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

• Cardiac Output

• amount of blood pumped by ventricle per contraction

• Systole

• amount of heart beats per min

• Heart Rate

• ventricle contracting & pumping blood

Match the following terms with their definitions.

• ECG/EKG

• measure of electrical activity produced by SA & AV nodes

• Cardiac Cycle

• nerves extending from bundles branches (up heart walls)

• Bundle Branches

• complete cycle of blood filling and pumping

• Purkinje Fibers

• 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.
