A&P2 EXAM 2 UPDATED ACTUAL QUESTIONS AND
CORRECT ANSWERS
Question:
1. Know the pulmonary and systemic circuit and the names
of the blood vessels that bring oxygenated and
deoxygenated blood to and from each circuit.
Answer:
Pulmonary: Blood to and from lungs. Pulmonary arteries carry blood from heart
to lungs while pulmonary veins carry blood from lungs to heart.
Systemic: Blood to and from tissues. Venae cave carries blood from tissues
(capillaries) to heart while the aorta carries blood from heart to tissues
(capillaries).
Question:
2. Understand the architecture of heart.
Answer:
Three dimensional hollow mass of muscle.
Double pump:
2 receiving chambers atria and 2 pumping chambers ventricles.
Fibrous skeleton.
Suspended in fluid filled pericardial sac.
, Question:
3. Know the names of the chambers, which chambers carry
oxygenated and deoxygenated blood.
Answer:
Right atrium: Receives deoxygenated blood from tissue.
Left atrium: Receives oxygenated blood from lungs.
Right ventricle: Pumps blood deoxygenated to lungs.
Left ventricle: Pumps oxygenated blood to tissues.
Right side carries deoxygenated blood while the left side carries oxygenated.
Question:
4. Know the names of the valves separating the chambers.
Answer:
Tricuspid: 3 cusps and seals right atrium from right ventricle.
(Bicuspid/mitral): 2 cusps and seals left atrium from left ventricle.
Semilunar valves: Look like half moons
Right/pulmonary - Separates right ventricle from pulmonary trunk
Left/aortic - Separates left ventricle from aorta
Question:
5. Know the layers of the heart wall.
Answer:
Pericardium: NOT PART OF THE HEART WALL. Outermost layer of heart.
Epicardium: Covering/surrounding the heart. Outermost layer of heart wall.
Myocardium: Literal muscle of the heart.
Endocardium: Blood/nutrients cannot get through. Inner most layer of heart wall.
