the heart chamber receiving oxygenated blood from returning veins is the
left atrium
The death of a portion of the heart muscle due to an obstruction of a coronary artery is called
myocardial infarction
Select the correct sequence of blood flow... artery, arteriole, capillaries, venule, vein The thickest layer of the heart wall is the
myocardium
Slect the correct sequence of impulse transmission in the heart
SA note, AV node, AV bundle, Purkinje fibers
The veins carrying oxygenated blood to the heart are the
Pulmonary veins
The ballooning of a portion of an artery because of a weak spot in its wall is called an
aneurysm
The left ventricle pumps blood directly into the
aorta
Chordae tendinae anchor the cusps of
atrioventricular valves
The type of muscle tissue forming the heart muscle is
cardiac muscle tissue
Blood returing to the right atrium is
deoxygenated
correct sequence of vessels in the flow of blood is
heart, arteries, capillaries, veins, heart
Chronic high blood pressure is known as
hypertension
Select the correct sequence of blood flow through the heart
right atrium, tricuspic AV valve, right ventricle, pulmonary semilunar valve, pulmonary trunk.
the pulmonary circuit carries blood to..
the lungs only
The right atrium receives blood directly from the
venae cavae
An atrioventricular valve prevents the flow of blood from a
ventricle to an atrium
