NUR 505 Exam 2 Questions with CORRECT
Answers (Grade A+)
Question 1:
Pericardium tough, double walled fibrous
Answer:
sac, encases and protects the heart
Question 2:
Epicardium thin outermost muscle layer,
vessels
Answer:
covers surface of the heart and extends onto the great
Question 3:
Myocardium: thick muscular layer
Responsible for pumping
Answer:
action of the heart
Question 4:
Endocardium innermost layer, lines the
muscles associated with opening
Answer:
chambers of the heart, heart valves, and the small
and closing the valves
,Question 5:
Atria small , thin walled structures
Act primarily as blood reservoirs
throughout the body
Answer:
for blood returning to the heart from the veins
Question 6:
Ventricles Large thick walled chambers
Pump blood to the lungs
Right and left ventricles =
Answer:
and throughout the body
primary muscle mass of heart
Question 7:
Atrioventricular tricuspid and mitral valves
valves Sit between the atria and
When the ventricles contract
from flowing back into the
Answer:
ventricles
(systole), AV valves snap shut = preventing blood
atria
Question 8:
Tricuspid valve Separates the right atrium
Answer:
from the right ventricle
,Question 9:
Mitral valve Separates the left atrium
Answer:
from the left ventricle
Question 10:
Semilunar valves: aortic and pulmonic valve
Each have 3 cusps
Contraction of the ventricles
Causes blood to rush into
When ventricles relax (diastole) the valves
Answer:
(systole) OPENS the semilunar valves
the pulmonary artery and aorta
close
Question 11:
Pulmonic valve Separates the right ventricle from the right
Answer:
pulmonary artery
Question 12:
Aortic valve Lies between the left ventricle and the aorta
Answer:
, Question 13:
S1 CLOSING OF THE MITRAL AND TRICUSPID
ventricular contraction raises the pressure
and tricuspid valves closed, preventing back
This valve closure: S1
Answer:
VALVE: S1
in the ventricles and forces the mitral
flow into the atria
Question 14:
S2 CLOSURE OF THE AORTIC AND PULMONIC
When the ventricles are almost empty, the
that in the aorta and pulmonary artery
closure of these valves causes the second heart
Answer:
VALVE: S2
pressure in the ventricles falls below
sound: S2
Question 15:
S3 passive ventricular filing
Answer:
Question 16:
S4 atria contract to ensure the ejection of any
Answer:
remaining blood
