Heart Study Guide
The bicuspid or mitral valve is located
between left atrium and left ventricle
Blood returning from the lungs enters the
left atrium
The left and right pulmonary arteries carry blood to the
lungs
The right ventricle pumps blood to the
lungs
The layer of the heart wall that contains cardiac muscle tissue, blood vessels, and nerves is the
myocardium
Blood leaving the right ventricle enters the
pulmonary artery
The following is a list of vessels and structures that are associated with the heart. 1. right atrium 2. left atrium 3. right ventricle 4. left ventricle 5. venae cavae 6. aorta 7. pulmonary trunk 8. pulmonary veins What is the correct order for the flow of blood entering from the systemic circulation?
5, 1, 3, 7, 8, 2, 4, 6
The pulmonary semilunar valve guards the entrance to the
pulmonary trunk
The "double pump" function of the heart includes the right side, which serves as the ____ circuit pump; the left side serves as the ____ pump.
pulmonary; systemic
Blood returning from the systemic circuit first enters the
right atrium
The entrance to the aorta is guarded by
semilunar valve
The left ventricle pumps blood to the
systemic circuit
The major difference between the left and right ventricles relative to their role in heart function is that
the left ventricle pumps blood through the high-resistance systemic circulation
The atrioventricular valve located on the right side of the heart is the
tricuspid valve
The portion of the pericardial membrane that lies on the surface of the heart is the
visceral pericardium
The right atrium receives blood from the
inferior vena cava
The folds of fibrous tissue that ensure a one-way flow of blood from the atria into ventricles are the
atrioventricular valves
The function of an atrium is to
collect blood
The heart's inner surface, including the heart valves, is covered by the
endocardium
The visceral pericardium (outer surface covering) is the same as the
epicardium
The left and right pulmonary veins carry blood to the
heart
