Question: What is the percentage of deaths caused by heart disease
Answer:
20.6
3 multiple choice options
Question: Perfusion
Answer:
the passage of nutrients and oxygenated blood through the body of cells and the removal of
cellular waste products, requires 3 systems working together: respiratory, cardiac, and helathy
RBC's
Question: Influences on circulation are:
Answer:
all of these
3 multiple choice options
Question: Risk factors for impaired perfusion
Answer:
modifiable: smoking, elevated cholesterol, sedentary lifestyle, obesity, diabetes, HTN,
personality unmodifiable: age, gender, genetics
Question: Central and local arteries
Answer:
termporal, carotid, brachial, popiliteal, pedal, posterior tibial, femoral, radial, apical
,Question: Identify hearts anatomy and blood flow:
Answer:
Question: Identify coronary arteries
Answer:
Question: Conduction system of the heart
Answer:
SA node triggers AV valve and contraction, travels to AV node triggering AP valve and
contraction, then Bundle of His
, Question: Hearts function

3 multiple choice options
Question: Cardiac output
Answer:
the amount of blood pumped from the left verticle/minute, normal range: 3-7 L/min (50-70%
output), depends on the relationship between HR and stroke volume (SV) ______ = HR x SV
*only the left side is measured since it pumps to the body
Question: Stroke volume
Answer:
the amount of blood ejected from the heart in one contraction.
Question: Afterload
Answer:
pressure ventricles must overcome to eject blood into the peripheral blood vessels, influenced
by the aortic or pulmonic valve
