FINAL PAPER QUESTIONS AND COMPLETE SOLUTIONS
⩥ What is the function of the pericardial fluid? Answer: The pericardial
fluid reduces the friction between it and its surrounding structures.
⩥ 1) visceral layer
2) pericardial fluid
3) parietal layer. Answer: Imagine a softly blown-up balloon with some
water inside of it. Now imagine pushing your fist into the side of that
balloon. You would now have three layers surrounding your fist; the first
layer would be the balloon immediately touching your fist (____1_____), the
second layer would be the water inside the balloon (_____2_____), and the
third layer would be the other side of the balloon (____3_____).
⩥ fibrous pericardium. Answer: It limits the motion of the heart. Due to its
tough, fibrous nature, the ___________ is able to resist stretch, which prevents
the heart from overexpanding.
⩥ fibrous pericardium. Answer: the ________ is able to resist stretch, which
prevents the heart from overexpanding
⩥ visceral and parietal. Answer: The serosal pericardium forms a closed sac
composed of two thin membranous layers:
, ⩥ pericardial cavity. Answer: Between the visceral and parietal layers is the
________ a narrow cavity filled with a thin serous fluid, called pericardial
fluid.
⩥ auricles; auricles. Answer: The atria possess small semi-elastic pouches
called ______ that expand when filled with blood. The _______ ensure that
there is sufficient blood volume to permit maximal contraction of the
ventricles.
⩥ What are the functions of auricles? Answer: The auricles ensure that
there is sufficient blood volume to permit maximal contraction of the
ventricles.
⩥ superior and inferior vena cava. Answer: A small, thin-walled chamber,
the right atrium receives deoxygenated blood from the entire body via the
___________.
⩥ atrioventricular (tricuspid) valve. Answer: The right atrium receives
blood from the myocardium itself through the coronary sinus and pumps
deoxygenated blood from the __________ into the right ventricle.
⩥ atrioventricular (bicuspid) valve. Answer: A small, thin-walled chamber
that forms much of the base of the heart, the left atrium receives
oxygenated blood from the lungs via the four pulmonary veins. It pumps
oxygen-rich blood from the __________ into the left ventricle.
⩥ Myocardium. Answer: Which layer of the heart wall is composed of
cardiac muscle fibers?
⩥ aeortic valve. Answer: between left ventricle and aeorta
