Cardiovascular System Quiz

What are the two circuits of the cardiovascular system?

• Pulmonic and Hepatic

• Systemic and Coronary

• Pulmonic and Systemic

• Coronary and Renal

Which circuit carries deoxygenated blood to the lungs for gas exchange and returns it to the heart?

• Systemic Circuit

• Coronary Circuit

• Renal Circuit

• Pulmonic Circuit

Which of the following best describes the function of the heart during systole?

• Atrioventricular (AV) valves are open and the ventricles are relaxed

• Semilunar valves are open and the ventricles contract

• Both AV and semilunar valves are closed

• Semilunar valves are closed and ventricles relax

What is the function of the pericardial fluid?

• Transports oxygen to the heart

• Prevents the heart from expanding too much

• Lubricates the membranes and allows the heart to beat with minimal friction

• Assists in the contraction of the myocardium

What are the three layers of the heart wall?

• Endocardium, Epicardium, Myocardium

• Myocardium, Pericardium, Epicardium

• Pericardium, Endocardium, Septum

• Epicardium, Endocardium, Peritoneum

Which heart chamber is the most posterior?

• Right Atrium

• Right Ventricle

• Left Atrium

• Left Ventricle

Which valve separates the left atrium from the left ventricle?

• Tricuspid Valve

• Aortic Valve

• Pulmonic Valve

• Mitral Valve

What are the names of the three cusps of the aortic valve?

• Right, Left, and Posterior

• Right, Left, and Anterior

• Anterior, Posterior, and Septal

• Right, Posterior, and Superior

Which chamber of the heart receives blood from the inferior and superior vena cava?

• Left Ventricle

• Right Atrium

• Left Atrium

• Right Ventricle

What is the primary function of the chordae tendinae?

• To prevent the tricuspid valve from prolapsing into the atria

• To support the ventricular walls during contraction

• To transport blood between the atria and ventricles

• To facilitate blood flow through the coronary arteries
