Q

A band of fibers that transmits impulses from the atrioventricular (AV) node to the top of the interventricular septum. It divides into the right and left bundle branches, which descend along the two sides of the septum; the bundle of His.

Q

Any sound produced as the heart functions normally

A

Functional murmur

18
Q

The muscular organ with four chambers that contracts rhythmically to propel blood through vessels to all parts of the body

A

Pulmonary artery

25
Q

The system of vessels that carries blood from the right side of the heart to the lungs to be oxygenated and then back to the left side of the heart

A

Pulmonary circuit

27
Q

The semilunar valve at the entrance to the pulmonary artery
