What prevents blood from flowing back into the atria when the ventricles contract?
semilunar valves
sinoatrial node
atrioventricular node
tricuspid and bicuspid valves
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
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

The sinoatrial node is often referred to as the:
semi lunar valve
the heart muscle
pacemaker of the heart
conductor of the heart
Which component of the ECG cycle shows ventricular depolarization?
P
QRS
T
U
Which is NOT a branch of the aortic arch.
L subclavian a
R subclavian a
Brachiocephalic trunk
L common carotid a
I have a large lumen, I have thin muscular walls.
Artery
Vein
Capillary
Arteriole
Inner layer of blood vessels. Made of epithelial tissue that protects the vessels and keeps it from rupturing.
Tunica intima
Tunica Media
Tunica Externa
Middle most layer of blood vessels. Made of smooth muscle.
Tunica Intima
Tunica Externa
Tunica Media
Outermost layer of blood vessels. Made of connective tissue.
Tunica Externia
Tunica Media
Tunica Intima
None of above
Vessels with walls that are one cell thick
arteries
capillaries
veins
Rank the following blood vessels in order of their average pressure, from highest to lowest: artery, vein, arteriole, venule, aorta, capillary.
Capillary > arteriole > venule > artery > vein > aorta
Capillary > vein > venule > arteriole > artery > aorta
Aorta > arteriole > venule > artery > vein > capillary
Aorta > artery > arteriole > capillary > venule > vein

Calculate cardiac output (in litres per minute or L/min) for an individual with a heart rate of 70bpm and a stroke volume of 100ml)
Q = 6L/min
Q = 9L/min
Q = 7L/min
Q = 8L/min
Write the equation for calculating cardiac output
Q = SV x HR
MV = TV x BPM
MHR = 220 - age
