questions Flashcards
Which of the following structures is associated with oxygen-rich blood?
The pulmonary veins
Which of the following structures does blood flow into AFTER the left ventricle?
Aorta
Which of these vessels supplies blood/nutrients to the heart (myocardium)?
Coronary arteries
Space of the chamber decreases, volume of fluid is same
What happens to pressure?
Increases
Space of the chamber increases, volume of fluid is same
What happens to pressure?
Decreases
Where would pressure be greater?
coming out of the left ventricle (systemic circuit—to the rest of the body)
Which set of valves are involved with the second heart sound?
Pulmonary and aortic valves
Which part of the conduction system is responsible for atrial systole?
SA node
A patient visits a physician for a second opinion about a diagnosed heart murmur affecting the right AV valve. Heart murmurs are caused by valve prolapse (the valve turns inside out).
Which of the following symptoms could the physician check to confirm the heart murmur?
A weak/missing first heart sound
If the right AV valve does not close completely and allows blood to pass through when it should be shut, then you could expect:
the output of the right ventricle to be decreased.
The semilunar valves prevent blood from flowing backwards into the
ventricles
Normal heart sounds are caused by which of the following events?
closing of the heart valves
Without SA node activity, what type of heart surgery would be indicated?
inserting an artificial pacemaker
Which of the following develops the greatest pressure on the blood in the aorta?
systole of the left ventricle
Among the following choices, which organism likely has the highest systolic pressure?
giraffe
