Coronary circulation is:

• Blood moving from the heart to the pulmonary circulation

• Blood moving from the heart to the systemic circulation

• Blood moving from the heart to the myocardium

• Blood moving from the systemic circulation to the heart

What is epicardium?

• the outermost layer of epithelial tissue of the heart wall

• the middle layer of of cardiac muscle cells of the heart wall

• the inner layer of endothelial cells (flattened epithelial cells) of the heart wall

What is myocardium?

• the outermost layer of epithelial tissue of the heart wall

• the middle layer of of cardiac muscle cells of the heart wall

• the inner layer of endothelial cells (flattened epithelial cells) of the heart wall

What is endocardium?

• the outermost layer of epithelial tissue of the heart wall

• the middle layer of of cardiac muscle cells of the heart wall

• the inner layer of endothelial cells (flattened epithelial cells) of the heart wall

Blood enters the heart from the systemic circulation from the:

• Pulmonary trunk

• Superior vena cava and inferior vena cava

• aortic arch

• pulmonary veins

The heart pumps blood into the lungs via

• pulmonary trunk

• aorta

• Left ventricle

• superior and inferior vena cava

True or false: left ventricular myocardium is thicker than right ventricular myocardium

• True

• False

systole is

• heart chambers contract

• heart chambers relax

• heart fills with blood
