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