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
