Arteries carry blood back to the heart

• True

• False

The following chambers of the heart are rich with oxygenated blood

• Left atrium and left ventricle

• Right atrium and right ventricle

The atria receive blood before delivering it down into the ventricles to be ejected out again

• True

• False

The heart has a double-circulatory system. The systemic circuit delivers blood to the lungs and brings it back to the heart

• True

• False

The valve that separates the left atrium and the left ventricle is known as the...

• Tricuspid valve

• Semilunar valve

• Bicuspid valve

What is this describing? Thin muscular wall, pocket valves and large lumen.

• Capillary

• Vein

• Artery

The primary role of the capillary is to...

• Carry blood away from the heart at high pressure

• Return blood to the heart

• Allows gaseous exchange of oxygen and carbon dioxide at the lungs and muscle sites

Cardiac output is...

• The amount of blood pumped out of the left ventricle during each contraction

• The volume of blood pumped per minute by each ventricle of the heart

Cardiac output calculated by using the following equation:

? x stroke volume(ml) = Cardiac output(L/min)

• Breathing rate

• Heart rate

• Intensity of exercise

The role of the red blood cells is to...

• Carry oxyge back to the heart

• Carry oxygen to the working muscle and carbon dioxide back to the lungs for gaseous exchange
