Review – Cardiovascular
Chapter 14 – Cardiovascular - 21 pts
Chapter 15 – Circulatory– 7 pts
The Highlight Reel (things to focus on):
Wiggers Diagram!!!
Label the curves and the time periods – know when the valves are open and when they
are closed.
Basic anatomy – chambers, valves, pressure ranges of each
Myocardial ischemia and infarct
Heart Failure
The basics of the ECG - conditions that affect the ECG.
Valve abnormalities
Properties of each of the blood vessel types
Blood flow – and what affects it.
Vessel conditions – atherosclerosis, varicose veins
Cardiovascular Questions:
Define Stroke Volume.
amount of blood pumped in 1 beat
The blood pumped per minute is called.
cardiac output
Define myocardial ischemia.
decreased blood blow to the <3 cause by partial blockage of coronary artery
What is a cause of ischemia and heart attack?
a blockage of the coronary artery
Why does the heart have valves?
to keep blood moving in one direction, to ensure proper flow with strong pressure
Name the 4 chambers of the heart.
r atrium, r ventricle, l atrium, l ventricle
What is systole and diastole.
systolic pressure is the higher of the two pressures. it occurs during ejection phase.
diastole is the weaker of the pressures and occurs during the filling phase (time between
isovolumetric relaxation and isovolumetric contraction)
Why is high blood pressure dangerous?
the higher the bp is the more work the <3 muscle is doing which means it can become
fatigued which will lower sv. which will increase hr, which fatigues it more, which
lowers it more untill you die
In what blood vessel does gas exchange occur?
cappillaries
What is a characteristic of arterioles?
