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
