What causes the lubb dubb sounds of the heart correct answersthe closing of the tricuspid and
mitral valves and semilunar valves
Where is the heart located? correct answersunderneath the mediastinum
a hollow, cone-shaped, muscular pump located within the mediastinum of the thorax and resting
upon the diaphragm correct answersheart
the outer most layer of the covering of the heart correct answersfibrous pericardium
a double layer that covers the heart and turns back upon itself to form another layer of the heart's
covering correct answersvisceral pericardium
covering of the heart that is formed by the folding of the visceral pericardium correct
answersparietal pericardium
covering of the heart made of tough, white fibrous connective tissue correct answerspericardium
space between the parietal and visceral layers correct answerspericardial cavity
serous fluid secreted by the pericardial membranes that reduces friction between the pericardial
membranes as the heart moves inside correct answerspericardial fluid
outer covering of the walls of the heart; protective layer; consists of connective tissue covered by
epithelium, blood, and lymph capillaries, nerve fibers, some fat, and coronary arteries and veins
which provide blood flow through the middle layer correct answersepicardium
, middle layer of the wall of the heart; thick and consists of muscle tissue that pumps blood out of
the heart chambers; pumps 70 ml of blood with each contraction correct answersmyocardium
layer of the walls of the heart that contains blood vessels and specialized cardiac muscle fibers
called Purkinje fibers; forms a protective inner lining or chambers and valves; is also continuous
with the inner lining of blood vessels attached to the heart correct answersendocardium
