Individuals with type O blood can donate blood to anyone because...

• their RBCs have Rh antigens on them

• they are known as the universal recipient

Both ventricles of the heart...

• are lower chambers of the heart

• are activated by the AV Node and Purkinje Fibers

• squeeze blood out of the heart

• All of these

The right ventricle...

• pumps blood into the lungs

• pumps blood into the aorta and out to the rest of the body

• receives blood from the left atrium

• moves oxygenated blood

The left ventricle...

• pumps blood into the lungs

• is activated by the SA node

• receives blood from the atrium through the bicuspid/mitral valve

• moves oxygenated blood

The ____ and ____ keep the valves from opening the wrong direction (keeping the blood from flowing back into the atria from the ventricles)

• epithelial tissue and cardiac muscle

• papillary muscle and ligaments

• cardiac muscle and chordae tendinae

• papillary muscle and chordae tendinae

What does blood deliver to the cells of the body (including to the heart itself- via the coronary arteries)?

• Nutrients and oxygen

• Carbon dioxide and oxygen

• Nutrients and carbon dioxide

• Oxygen and carbon dioxide

If the coronary arteries become blocked (due to a build up of fats in the blood vessels), it can cause the heart not to get the oxygen and nutrients it needs, triggering a...

• heart attack

• arrhythmia

• anemia

• deep vein thrombosis
