System Questions With Complete Solutions
Circulatory System Cardiovascular System (heart/blood) + Lymphatic System (lymph)
Arteries Move blood away from the heart (blood in arteries is usually highly oxygenated, except
for the pulmonary artery)
Capillaries Site of gas exchange between blood and tissues
Veins Bring blood towards the heart (blood in veins is usually deoxygenated, except for the
pulmonary vein)
Venae Cavae The vein that carries blood back to the heart
Atrioventricular Valves Tricuspid (right) and bicuspid (left) valves separate the atria and the
ventricles of the heart
Semilunar Valves Pulmonary valve and aortic valve prevent back flow of blood between the
lungs and aorta

System Questions With Complete Solutions
Pulmonary Circulation Pulmonary arteries carry oxygen deficient blood to the lungs to be
oxygenated, the oxygenated blood is then returned to the heart via pulmonary veins.
Systemic Circulation Oxygen rich blood is pumped from the heart into the aorta and is routed to
arteries that branch to become arterioles, which branch into capillaries.
In the capillaries, blood is provided to bodily tissues, and oxygen is exchanged for CO2.
De-oxygenated blood then returns to venules, then veins, and is returned to the heart via the
superior or inferior venae cavae.
Pericardium Serous membrane enclosing the heart; the inner-most layer is called the visceral
pericardium, or the epicardium
Endocardium Smooth surface lines the inside of the heart's chambers and forms the surface of
the valves
Myocardium The heart itself; a muscular layer capable of contractions
Coronary Arteries Blood vessels that supply blood to the heart (coronary = encircling)
