What prevents blood from flowing back into the atria when the ventricles contract?
semilunar valves
sinoatrial node
atrioventricular node
tricuspid and bicuspid valves
When blood leaves this chamber of the heart, it heads out to the body (not the lungs)
left atrium
right atrium
left ventricle
right ventricle
When this chamber contracts, it pushes blood through the tricuspid valve
right atria
right ventricle
left atria
left ventricle
This initiates the action potential that causes the heart to beat
Inferior vena cava
Atrioventricular node (AV node)
Superior vena cava
Sinoatrial node (SA node)
This stops blood from flowing back into the ventricles each time they contract
semilunar valves
tricuspid and bicuspid valves
Sinoatrial node (SA node)
Aorta
This is responsible for distributing electrical impulses through the heart
Atrioventricular node
Sinoatrial node
Inferior vena cava
Superior vena cava
This blood vessel splits in two and sends oxygen-poor blood away from the heart and to the lungs
aorta
pulmonary veins
superior vena cava
pulmonary trunk

arteries
veins
capillaries
aorta
Which best explains why capillary walls are so thin?
because they do not need to pump blood
because they are found only in the smallest organs and tissues
because they maximize diffusion of nutrients
because blood only travels through them slowly
These carry blood towards the heart
arteries
veins
These carry blood away from the heart
Arteries
Veins
Which of the following is FALSE about pacemaker cells?
They allow the heart to beat on its own
They create their own electrical impulses
They are part of the sinoatrial node and the atrioventricular node
They require depolarizing stimulation from the brain
Why is coronary circulation necessary?
because blood needs to be pushed throughout the entire body
because the heart itself needs nourishment
because the scalp requires an exceptional amount of nourishment
Blood in capillary beds flows from
arteries to veins
veins to arteries
