_______ _____ closely parallel the coronary arteries but receive deoygenated blood from the heart's tissues and join a large vein, the ________ _____, on the posterior surface of the heart. The coronary sinus empties into the _____ atrium.

Cardiac veins; coronary sinus; right

_____ transport blood towards the heart

Veins

The left ventricle sends blood to the body via the _____

aorta

The ______ semilunar valve separates the left ventricle from the aorta

aortic

Inside the heart there are two _____ which receive blood from the body and consist of thin walls

atria

The ________________ valves (also known as the tricuspid and bicuspid valves) separate atria from ventricles and ensure the ___-way flow of blood

atrioventricular; one

Both atria have attached ear-like ________ which slightly increase the volume of the atria

auricles

The ________ (mitral) valve separates the left atrium from the left ventricle

bicuspid

Extending off the "base" of the aorta are two small branches which extend around the heart and form the left and right ________ ________. These vessels supply the myocardium with oxygen and nutrients.

coronary arteries

The right chambers inside the heart are separated from the left chambers by the ________________ ______

interventricular septum

Pulmo means _____

lungs

The left and right chambers are separated to prevent mixing of deoxygenated blood and __________ _____

oxygenated blood

The _________ semilunar valve separates the right ventricle from the pulmonary trunk

pulmonary

The left atrium receives blood from the left and right _________ veins

pulmonary

The right ventricle sends blood to the lungs via the _________ _____ which branches into the left and right _________ ________

pulmonary trunk; pulmonary arteries

The _________ valves separate the ventricles from the major arteries

semilunar

The right atrium receives blood from the (1) ________ ____ ____, (2) the ________ ____ ____ and (3) the ________ _____

superior vena cava; inferior vena cava; coronary sinus
