epicardium
pericardium
endocardium
myocardium
The human cardiovascular system has two loops. Which loop takes blood from the heart to the body tissues and back?
pulmonary loop
coronary loop
systemic loop
systolic loop
Which type of blood vessel contains blood at the highest pressure?
veins
arteries
capillaries
shunts
Blood passes from the legs into the _______ vena cava and then into the ____________.
inferior, right atrium
inferior, left atrium
superior, right atrium
superior, left atrium
The major blood vessel that carries oxygenated blood away from the heart is the

True
False
Which of the following is the correct sequence for the intrinsic conduction system?
SA node → AV node → AV bundles → Purkinje fibers → bundle branches
AV node → AV bundles → SA node → bundle branches → Purkinje fibers
AV node → AV bundles → Purkinje fibers → bundle branches → SA node
SA node → AV node → AV bundles → bundle branches → Purkinje fibers
Which of the following chambers of the heart are involved in the “ejection phase” of the cardiac cycle?
right atrium and left atrium
right ventricle and left ventricle
right atrium and right ventricle
left atrium and left ventricle
Which is the correct formula for calculating cardiac output?
cardiac output = stroke volume + heart rate
cardiac output = stroke volume – heart rate
cardiac output = stroke volume x heart rate
cardiac output = stroke volume/heart rate
Three tissue layers are found in:
the arteries
the veins
the arteries and veins
the capillaries
After eating a meal, your hands and feet feel cold because blood is being directed to your stomach. How does this occur?
The capillary sphincters restrict blood flow from the shunt to the true capillaries.
The shunt restricts blood flow from the capillary sphincters to the true capillaries.
The capillary sphincters restrict blood flow from the true capillaries to the shunt.
The shunt restricts blood flow from the true capillaries to the capillary sphincters.
Negative feedback loop would be which of the following?
Also called the cardiac pacemaker
