b. separate sections of the heart
c. prevent backflow
d. prevent mixing of oxygenated and deoxygenated blood

A

c. prevent backflow

24
Q

which valve prevents backflow to the right ventricle when the ventricles relax?

a. bicuspid
b. pulmonary sl
c. tricuspid
c. aortic semilunar

A

b.pulmonary sl

25
Q

what ridge of specialised muscle transmits impulses to anterior papillary muscles ?

a. trabeculae carneae
b. interventricular septum
c. septomarginal trabeculae
d. chodae tendinae

A

c.septomarginal trabeculae

branches from IV septum

26
Q

what is the name of the rough part of the ventricular wall?

a. trabeculae carneae
b. pectinate muscle
c. crista terminalis
d. sulcus terminalis

A

a.trabeculae carneae

27
Q

2 openings superior to which valve lead to the left and right coronary artery?

a. aortic semilunar
b. pulmonary semilunar
d. bicuspid
e. tricuspid

A

a.aortic semilunar

When aortic valve closes, blood falls back toward
ventricle, filling the cusps & closing the valve
& enters openings of coronary aa.
