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)
When blood leaves this chamber of the heart, it heads to the lungs
right atrium
right ventricle
left atrium
left ventricle
This is responsible for distributing electrical impulses through the heart
Atrioventricular node
Sinoatrial node
Inferior vena cava
Superior vena cava
This chamber of the heart receives oxygenated blood from the lungs
right atrium
right ventricle
left atrium
left ventricle
These are the smallest blood vessels with the thinnest walls in order to maximize diffusion of nutrients in and out of the interstitial fluid
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
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
Which of these two is a function of the cardiovascular system?
Provides cells with nutrients
Helps to keep carbon dioxide in your blood
Protects the body against disease and infection
Does not help with blood clots
What is the function of the blood? Pick three answers
Transport oxygen from the lungs to the cells
Regulate body temperature
Fights off diseases and infections
Transports water around the body
Transports carbon dioxide around the body
The bicuspid or mitral valve is located
in the opening of the aorta.
in the opening of the pulmonary trunk.
where the venae cavae join the right atrium
between the left atrium and the left ventricle
Compared to arteries, veins
are more elastic.
have more smooth muscle in their tunica media
hold their shape better when cut.
have thinner walls
The watery liquid (non-living matrix) portion of the blood is
leukocytes
erthryocytes
plasma
thrombin
Red blood cells will do this if they encounter the wrong antibodies...
swell
agglutinate (clump)
dehydrate
no reaction will occur

Maxwell has lost a lot of blood and needs a transfusion. Doctors at the hospital have identified that he has A- blood type, which means he also has B and Rh antibodies in his plasma. Select the blood types he can safely receive?
