,

(b) Gastrovascular System

,

(c) Open Circulatory System

,

(d) Closed Circulatory System

• 
• Inefficient (1)

• 
• Inefficient (2)

• Directional flow of food and oxygen

• Requires lots of energy & many complicated tubes

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

• Keeps digested food near tissues

• 
• Blood

• Water & food passes through

• Water passes through

• 
• Hemolymph

• Keeps food and oxygen moving throughout body

Answer explanation

Match the following terms with their definitions.

• Systole

• amount of heart beats per min

• Cardiac Output

• amount of blood pumped by ventricle per contraction

• Stroke Volume

• ventricle relaxing & filling blood

• Heart Rate

• ventricle contracting & pumping blood

• Diastole

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

Match the following terms with their definitions.

• Cardiac Cycle

• 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)

• Purkinje Fibers

• nerves extending from NA node (down septum)

Compare arteries and veins.

Groups:

(a) Artery

,

(b) Vein

• Thicker Smooth Muscle & Connective Tissue

• Valves

• Thinner Endothelium

• Thinner Smooth Muscle & Connective Tissue

• Thicker Endothelium

• No Valves

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.
