Left ventricle.
Right ventricle.
The left ventricle
The left atrium
The pulmonary veins
The pulmonary arteries
Capillaries that line the small intestine
Left atrium.
Right atrium.
Left ventricle.
Right ventricle.
Semilunar valves in the aorta.
Some sort of pumping device helps to move blood through the body.
Some of the circulation of blood is a result of movements of the body.
The blood and interstitial fluid are distinguishable from each other.
All tissues come into close contact with the circulating body fluid so that the exchange of nutrients and wastes can take place.
Blood is pumped at two separate locations as it circulates through the body.
There is a countercurrent exchange within the gills.
Hemolymph circulates both through a pumping blood vessel and through body sinuses.
Blood is pumped to the gas-exchange organ and returning blood is then pumped through systemic vessels.

A blood protein that escorts lipids through the circulatory system.
A cell fragment involved in the blood-clotting mechanism.
A blood protein that is converted to fibrin to form a blood clot.
A leukocyte involved in trapping viruses and bacteria.
The flow of fluids (water and blood) in opposite directions maintains a favorable diffusion gradient along the length of an exchange surface.
Double circulation keeps oxygenated and deoxygenated blood separate.
Oxygen moves from a region of high partial pressure to one of low partial pressure, but carbon dioxide moves in the opposite direction.
The capillaries of the lung pick up more oxygen than do tissue capillaries.
An artery has a thicker muscular and connective tissue layer than does a vein.
Veins do not have valves and arteries do.
Blood is under lower pressure in arteries than in veins.
Arteries carry blood to the heart; veins carry blood away from the heart.
Blood in arteries is oxygen rich; blood in veins is always oxygen poor.
Have a closed circulatory system.
Have an open circulatory system.
Have no interstitial fluid.
Have no cardiovascular system.
