HHP 3114 Exam 3


Which of the following is not considered a function of the cardiovascular system

a. secretion of hormones
b. delivery of o2 and other nutrients
c. removal of co2 and other metabolic waste
d. thermoregulation, and maintaining acid-base balance
e. overall fluid balance

The primary function of the cardiovascular system is
ensuring that there is adequate blood flow throughout the circulation to meet the
metabolic demands of the tissue

The circulation originating from the left side of the heart is the
systemic circulation

The circulation originating from the right side of the heart is the
pulmonary circulation

The major artery returning blood to the heart is the
coronary artery

The pumping chambers of the heart that deliver blood to the lungs and body tissues are
called the
Ventricles

The portion of the heart that pumps blood to the body is called the
left ventricle

The heart receives its nervous control from
both the sympathetic and parasympathetic nervous systems

Deoxygenated blood
is pumped from the right ventricles into the pulmonary arteries

The normal "pacemaker" of the heart is the
sinoatrial node

The heart's main nutrient blood supply is provided via
the right and left coronary arteries

The T-wave represents
repolarization of the ventricles

, The P-wave represents
depolarization of the atria

The QRS complex represents
depolarization of the ventricles

An electrocardiogram is a
recording of the heart's electrical activity

Sequence of events for a normal EKG
SA node, AV node, bundle of His, Purkinje fibers

Bradycardia is generally defined as
resting heart rate below 60 bpm

The cardiac cycle is
the time between one systole to the next systole

The volume of blood pumped by the heart per minute is referred to as
cardiac output

The volume of blood ejected from the heart with each contraction is called
stroke volume

Stroke volume equals
end diastolic volume minus systolic volume

What phase of the cardiac cycle does the diastolic pressure reflect?
Relaxation

The volume of blood in the ventricles at the end of ventricular filling is called
end diastolic volume

The most important variable that determines resistance to blood flow is
the diameter of the vessel

Skeletal muscles receive approximately ________% of the total cardia output under
resting conditions, but they can receive as much as _____% of the cardia output during
heavy endurance exercise
15; 80

The ratio of formed elements in the blood (red cells, white cells, platelets) to the total
blood volume is
Hematocrit
