Questions with 100% Verified Answers UPDATED!!!
Name the four chambers and four valves in the heart. -
ANSWER 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. - ANSWER 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? - ANSWER 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),
,2|Page
left ventricle, (E), aorta, arteries, arterioles, capillary bed,
venules, veins, superior and inferior vena cava. - ANSWER A-
right atria, B-pulmonary valve, C-left atria, D-mitral valve, E-
aortic valve
What is the function of the capillary bed? - ANSWER 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? - ANSWER 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. - ANSWER A pulse is the rhythmic
wave in the wall of an artery that corresponds to the heartbeat.
, 3|Page
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. -
ANSWER 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. - ANSWER 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? - ANSWER 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.
