A&P II TEST 2 EXPECTED QUESTIONS
WITH VERIFIED ANSWERS
Question 1.
cardiovascular/circulatory system
ANSWER
comprised of the heart, arteries, veins, and capillaries
Question 2.
mediastinum
ANSWER
central compartment within the thoracic cavity (from thoracic aperture to diaphragm between
pleural cavities)
Question 3.
heart, major blood vessels, thymus gland, esophagus, trachea, nerves
ANSWER
mediastinum contents (6)
Question 4.
apex of the heart
ANSWER
inferolateral portion of the left ventricle, located posterior to the 5th intercostal space -
auscultation point for bicuspid valve
Question 5.
pericardium
ANSWER
sac that surrounds the heart (fibrous and serous)
,Question 6.
fibrous pericardium
ANSWER
outer layer of dense irregular CT (to withstand force in multiple directions), continuation of
central tendon of the diaphragm
Question 7.
serous pericardium
ANSWER
simple squamous epithelium (parietal - helps product pericardial fluid) over loose connective
tissue (visceral - envelops the actual heart)
Question 8.
fixation, prevents overfilling, lubrication, protection
ANSWER
pericardium functions (4)
Question 9.
epicardium
ANSWER
outer layer of the heart wall, made up of serous pericardium (continuation of visceral
pericardium)
Question 10.
myocardium
ANSWER
middle, muscular layer of the heart wall
, Question 11.
endocardium
ANSWER
innermost layer of the heart wall, lines inner chambers of the heart
Question 12.
fibrous skeleton of the heart
ANSWER
composition of dense connective tissue (strong!) that anchors heart valves, maintains valve
integrity, serves as muscular attachment points, and acts as an electrical insulator
Question 13.
tricuspid value
ANSWER
atrioventricular valve between the right atrium and the right ventricle
Question 14.
bicuspid valve
ANSWER
atrioventricular valve between the left atrium and the left ventricle
Question 15.
pulmonary valve
ANSWER
semilunar valve between the right ventricle and the pulmonary trunk
Question 16.
aortic valve
ANSWER
semilunar valve between the left ventricle and the aorta
