• 
• Blood

• 
• Water passes through

• Inefficient (1)

• Hemolymph

• Directional flow of food and oxygen

• Water & food passes through

• Inefficient (2)

• 
• Requires lots of energy & many complicated tubes

• 
• Simple and can't seen oxygen or food to particular places

• Keeps food and oxygen moving throughout body

• Keeps digested food near tissues

Match the following terms with their definitions.

• Systole

• ventricle relaxing & filling blood

• Diastole

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

• Cardiac Output

• amount of heart beats per min

• Heart Rate

• ventricle contracting & pumping blood

• Stroke Volume

• amount of blood pumped by ventricle per contraction

Match the following terms with their definitions.

• ECG/EKG

• nerves extending from NA node (down septum)

• Cardiac Cycle

• complete cycle of blood filling and pumping

• Purkinje Fibers

• nerves extending from bundles branches (up heart walls)

• Bundle Branches

• measure of electrical activity produced by SA & AV nodes

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.
