Myocardium

Thickest layer; made of muscle and performs the work of the heart

Endocardium

Covers the valve surfaces and is continuous with the endothelium of the blood vessels

Epicardium

Serous membrane; mainly simple squamous epithelium over areolar connective tissue with an adipose covering

What are the thick inferior chambers of the heart that pump blood into the arteries called?

Ventricles

fossa ovalis- shallow depression in wall between the two atria

pectinate muscles- comb-like muscular ridges inside the atrial wall

papillary muscles- finger-like projections that anchor the chordae tendineae.

Which of the following superficially separates the atria from the ventricles?

Coronary sulcus

Which of the following are found on the surface of the heart?

• Coronary sulcus

• Anterior interventricular sulcus

• Posterior interventricular sulcus

The passage of blood from the atria to the ventricles is regulated by which valves?

Atrioventricular

Place the labels in numerical order denoting the flow of blood through the pulmonary circuit beginning with the right atrium and ending in the left atrioventricular valve

Correctly sequence the pathway of blood flow through the heart, beginning with the venae cavae.
