and removing wastes from them
The ____ is the strongest muscle in the body - answerheart
What is the right side of the heart responsible for? - answerpumping blood into your lungs and
oxygenating it
What is the left side of the heart responsible for? - answerdistributing oxygenated blood throughout the
body
The heart is actually a ___-barreled, __-chambered pumper - answer2 ; 4
The two sides of the heart (do/do not) work independently - answerdo not
What causes the lubb dubb sounds of the heart - answerthe closing of the tricuspid and mitral valves
and semilunar valves
Where is the heart located? - answerunderneath the mediastinum
a hollow, cone-shaped, muscular pump located within the mediastinum of the thorax and resting upon
the diaphragm - answerheart
the outer most layer of the covering of the heart - answerfibrous pericardium
a double layer that covers the heart and turns back upon itself to form another layer of the heart's
covering - answervisceral pericardium
, covering of the heart that is formed by the folding of the visceral pericardium - answerparietal
pericardium
covering of the heart made of tough, white fibrous connective tissue - answerpericardium
space between the parietal and visceral layers - answerpericardial cavity
serous fluid secreted by the pericardial membranes that reduces friction between the pericardial
membranes as the heart moves inside - answerpericardial 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 - answerepicardium
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 - answermyocardium
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 - answerendocardium
The heart has _______ circulation (or 2 pathways thata blood leaving the heart maay go) -
answerdouble
circulation that takes blood to the lungs - answerpulmonary
