A drop is in the right ventricle during systole and is ejected out of the heart. Which large vessel does it enter next?

After the single vessel leaving the right ventricle splits toward each lung, a drop flows into which vessels next?

A drop has passed through capillaries wrapped around alveoli and is leaving the lung tissue. Which vessels carry it next toward the heart?

A drop in the right atrium is moving toward the right ventricle. Which valve does it cross next?

A drop leaves the left ventricle during systole. Which large vessel receives it next?

A drop has entered the aorta and is moving away from the heart to the body wall. Which type of vessel does it enter next?

As a drop moves from a systemic artery toward a thigh muscle capillary bed, which smaller vessel comes next?

After a drop leaves a systemic capillary bed in the hand, which small vessel does it enter next?

Veins from the lower abdomen and legs merge into one large vessel before the heart. What does the drop enter next?

A drop in the superior vena cava is at the heart's entrance. Which chamber does it enter next?

A drop leaves the heart's right side, passes through vessels of the lungs, and returns to the left atrium. Which circuit is this?

A drop leaves the left ventricle, reaches capillaries in the kidney, and returns to the right atrium. Which circuit carried it?

Which circuit carries blood at lower pressure, matching the thinner wall of the ventricle that pumps it?

A drop delivers oxygen to the cells of the small intestine before returning to the heart. Which circuit is it traveling?

A drop moves from the heart to the lungs so gas exchange can load oxygen before it returns. Which circuit is that leg?

A drop leaves the heart for brain capillaries and later enters a vena cava. Which circuit did it travel?

A drop in the superior vena cava has just returned from body tissues. What is its oxygen state and first chamber?

The pulmonary trunk is an artery. What oxygen state does the blood inside it have?

A drop inside a pulmonary vein is nearing the heart. What oxygen state and chamber pairing is correct?

A drop in the aorta has just left the left ventricle. What oxygen state does it normally have?

After a drop passes through systemic capillaries in a forearm muscle, what state is expected as it enters venules?

A drop in the right ventricle is about to be pumped toward the lungs. What oxygen state is it in?

A drop has just crossed the capillaries around alveoli and is heading back to the heart. Which state and side match it?

Just past the aortic valve, some blood immediately branches off into small vessels that supply the heart wall itself. Which vessels are these?

Blood returning from the lungs approaches the heart in veins. Which chamber receives that blood first?

Blood flows from the right atrium through the tricuspid valve. Which chamber does it reach next?

Blood flows from the left atrium through the bicuspid, or mitral, valve. Which chamber does it reach next?

Blood coming from the liver and legs arrives through the large lower-body vein. Which chamber receives it first?

Blood is ejected from the right ventricle toward the lungs. Which valve does it pass through as it leaves the heart?

After a drop returns from the heart muscle through the coronary sinus, which chamber receives it?
