Heart Anatomy
The two superior chambers of the heart
What are the left and right atria?
(Or atria)
What is the aorta?
What is the tricuspid valve?
The two inferior chambers of the heart
What are the left and right ventricles?
(or ventricles)
The valve between the left atrium and the left ventricle
What is the mitral valve?
(Or bicuspid)
The muscular layer of the heart
The largest veins in the body
What are the vena cava?
(Or SVC/IVC or superior vena cava/inferior vena cava)
Oxygenated blood flows from this vessel out to the rest of the body
What is the aorta?
The thin sac that contains the heart
What is pericardium?
The valve between the right ventricle and the pulmonary trunk
What is the pulmonary valve?
The wall that separates the atria
What is the atrial septum?
These blood vessels supply oxygenated blood to the myocardium
Oxygenated blood flows from the left atrium to the left ventricle through this valve
What is the mitral valve?
The wall that separates the ventricles
What is the ventricular septum?
The valve between the left ventricle and the aorta
What is the aortic valve?
This side of the heart contains deoxygenated blood.
What is the right side of the heart?
This blood vessel collects deoxygenated blood from the myocardium
What is the coronary sinus?
These vessels return oxygenated blood from the lungs to the left atrium
What are the pulmonary veins?
The left side of the heart contains this type of blood.
What is oxygenated blood?
The valve between the right atrium and the right ventricle
What is the tricuspid valve?
What are the papillary muscles?
This blood vessel carries deoxygenated blood from the right side of the heart to the lungs
What is the pulmonary artery?
The three anatomic sites from which deoxygenated blood drains into the right atrium
What are the inferior vena cava, superior vena cava, and the coronary sinus?
These thin fibrous strings connect the papillary muscles to the atrioventricular valves
What are chordae tendinae?
The vein that and has no valves
What is the coronary sinus?
