This quiz contains 13 questions from a mix of 1 subtopics.
What separates the two sides of the heart containing oxygenated and deoxygenated blood?
septum
atrium
ventricle
valve
|
Why does the heart have two separate pumping mechanisms?
to slow down the blood flow to the body cells
to allow mixing of oxygenated and deoxygenated blood
to increase the pressure before the blood circulates
because blood pressure increases in the lungs
|
Which valve is located between the right atrium and right ventricle?
tricuspid valve
mitral valve
semi-lunar valve
bicuspid valve
|
The bicuspid (mitral) valve is located between which two chambers?
left ventricle and aorta
right atrium and right ventricle
left atrium and left ventricle
right ventricle and pulmonary artery
|
What is the function of the atrioventricular valves?
to prevent backflow of blood into the ventricles when they relax
to prevent backflow of blood into the atria when the ventricles contract
to move oxygenated blood into the left atrium from the lungs
to move deoxygenated blood from the right ventricle to the lungs
|
Where are the semi-lunar valves located?
between the ventricles and the vena cava and pulmonary vein
between the ventricles and the pulmonary artery and the aorta
between the atria and the vena cava and pulmonary vein
between the atria and ventricles
|
Which blood vessel moves oxygenated blood into the left atrium from the lungs?
pulmonary vein
pulmonary artery
aorta
vena cava
|
The aorta moves oxygenated blood from which chamber to the body?
left ventricle
right atrium
right ventricle
left atrium
|
Which blood vessel moves deoxygenated blood into the right atrium from the body?
pulmonary vein
vena cava
aorta
pulmonary artery
|
Why do the ventricles have thicker walls with more muscle than the atria?
the ventricles require less pressure to pump blood
the ventricles require more pressure to pump blood a long distance
the atria require more pressure to pump blood
the atria require more pressure to pump blood a short distance
|
Which ventricle has a thicker wall with more muscle?
right ventricle
neither ventricle has a thick wall
left ventricle
both ventricles have the same thickness
|
Which side of the heart contains oxygenated blood?
neither
both
left
right
|
Explain why the left ventricle has a thicker wall with more muscle than the wall of the right ventricle.
