hemodynamics, plus related lab anatomy


SECTION 1 – Heart Anatomy (Q1–15)
Q1. Which chamber of the heart pumps oxygenated blood into the systemic circulation?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
E. Coronary sinus
D. Left ventricle
The left ventricle pumps oxygenated blood into the aorta and systemic circulation.


Q2. Blood returning from the systemic circulation first enters which chamber?
A. Left atrium
B. Right atrium
C. Left ventricle
D. Right ventricle
E. Pulmonary trunk
B. Right atrium
Deoxygenated blood from the body enters the right atrium via the venae cavae.


Q3. Which valve prevents backflow of blood from the right ventricle into the right atrium?

,A. Mitral valve
B. Aortic valve
C. Pulmonary valve
D. Tricuspid valve
E. Bicuspid valve
D. Tricuspid valve
The tricuspid (right AV) valve prevents regurgitation into the right atrium.


Q4. The left atrioventricular valve is also known as the:
A. Tricuspid valve
B. Pulmonary valve
C. Aortic valve
D. Mitral (bicuspid) valve
E. Semilunar valve
D. Mitral (bicuspid) valve
The mitral valve is the left AV valve.


Q5. Which layer of the heart wall contains cardiac muscle tissue?
A. Endocardium
B. Myocardium
C. Epicardium
D. Pericardium
E. Fibrous skeleton
B. Myocardium
The myocardium is the thick, muscular layer responsible for contraction.


Q6. The innermost layer of the heart wall that lines the chambers is the:
A. Myocardium
B. Endocardium
C. Epicardium

, D. Parietal pericardium
E. Fibrous pericardium
B. Endocardium
The endocardium is a smooth endothelial lining of the heart chambers and valves.


Q7. The fibrous sac that surrounds and protects the heart is the:
A. Myocardium
B. Endocardium
C. Pericardium
D. Epicardium
E. Mediastinum
C. Pericardium
The pericardium encloses the heart and roots of the great vessels.


Q8. Which vessel carries deoxygenated blood from the right ventricle to the lungs?
A. Aorta
B. Pulmonary veins
C. Pulmonary trunk/arteries
D. Superior vena cava
E. Inferior vena cava
C. Pulmonary trunk/arteries
The pulmonary trunk divides into left and right pulmonary arteries to the lungs.


Q9. Oxygenated blood returns from the lungs to the heart via the:
A. Pulmonary arteries
B. Pulmonary veins
C. Aorta
D. Superior vena cava
E. Coronary sinus
B. Pulmonary veins
Pulmonary veins carry oxygenated blood to the left atrium.
