Module 5 Problem Set QUESTIONS WITH
ANSWERS
Name the four chambers and four valves in the heart. -
CORRECT ANSWERS ✔✔Right and left atria, right and left
ventricles, tricuspid valve, pulmonary valve, mitral valve,
aortic valve.
List the three layers of the heart muscle starting with the
innermost layer. - CORRECT ANSWERS ✔✔The
endocardium, myocardium, and pericardium
What is the function of the right side of the heart? What is
the function of the left side of the heart? - CORRECT
ANSWERS ✔✔The function of the right side of the heart is
to receive the deoxygenated blood from the body tissues
and to pump it to the lungs. The function of the left side
of the heart is to receive oxygenated blood from the lungs
and to pump that blood out to the body tissues.
Fill in the blanks (A through E) to complete the route of
blood circulation starting and ending with the inferior and
superior vena cava.
,Inferior and superior vena cava, (A), tricuspid valve, right
ventricle, (B), pulmonary artery, lungs, pulmonary vein,
(C), (D), left ventricle, (E), aorta, arteries, arterioles,
capillary bed, venules, veins, superior and inferior vena
cava. - CORRECT ANSWERS ✔✔A-right atria, B-pulmonary
valve, C-left atria, D-mitral valve, E-aortic valve
What is the function of the capillary bed? - CORRECT
ANSWERS ✔✔The capillary bed consists of microscopic
blood vessels that deliver oxygen and nutrients to the
cells and removes CO2 and other waste products from
the cells.
Describe the flow of electricity through the heart. Where
does the electricity initiate? What stimulates the
contraction of the ventricles? - CORRECT ANSWERS
✔✔The flow of electricity starts in the sinoatrial node. It
travels through the internodal pathway through the atria
to the atrioventricular node. From the AV node, it travels
to the bundle of His and then into the two bundle
branches. The two bundle branches stimulate the
ventricles to contract
What is a pulse? Name 2 of the 7 common pulse sites.
Describe the difference between the systolic blood
pressure and the diastolic blood pressure. - CORRECT
ANSWERS ✔✔A pulse is the rhythmic wave in the wall of
an artery that corresponds to the heartbeat. The common
, pulse sites are the temporal, carotid, brachial, radial,
femoral, popliteal, and dorsalis pedis. The systolic blood
pressure is the pressure when the heart contracts, and
the blood is pumped against the artery walls. The
diastolic blood pressure is the pressure in the artery when
the heart is relaxed.
Name the structures in the airway that are responsible for
trapping foreign bodies in the air as it comes into the
lungs. - CORRECT ANSWERS ✔✔The mucous membranes
in the nose are responsible for producing mucus that
traps bacteria, dust, pollen, and other foreign bodies in
the air that is inhaled.
Trace the flow of air from the entry point in the nose to
the alveoli in the lungs. - CORRECT ANSWERS ✔✔Nose,
nasopharynx, oropharynx, laryngopharynx, larynx,
trachea, bronchi, bronchioles, alveoli.
What holds the trachea always open and why is that
important? What structures in the trachea prevent foreign
bodies from entering the lungs? - CORRECT ANSWERS
✔✔The trachea is held open by cartilage, and this is
important because the body constantly needs to breathe.
The trachea is lined with a mucous membrane that is
covered with cilia that can trap small foreign bodies in the
trachea and can sweep them out of the windpipe.
