The pulmonary valve lies between the right heart and the pulmonary trunk.
2.
The right ventricle tapers into the pulmonary trunk, into which it ejects blood when contracting.
3.
The infundibulum is the entrance from the right ventricle into the pulmonary artery and pulmonary trunk.
4.
A large pulmonary embolus affecting the pulmonary trunk is called a " saddle embolus ".
5.
The pulmonary trunk branches into the left and right pulmonary arteries that carry the blood to each lung.
6.
This allows the blood to be pumped out of the ventricles and into the aorta and pulmonary trunk.
7.
During embryological life, the ductus arteriosis connects the pulmonary trunk and the arch of aorta, allowing blood to bypass the lungs.
8.
Untreated, tetralogy of Fallot rapidly results in progressive right ventricular hypertrophy due to the increased resistance caused by narrowing of the pulmonary trunk.
9.
The truncus arteriosus is originally a single outflow tract from the embryonic heart that will later split to become the ascending aorta and pulmonary trunk.
10.
Initial secretion of bradykinin post-natally causes constriction and eventual atrophy of the ductus arteriosus, forming the ligamentum arteriosum between the pulmonary trunk and aortic arch.
the artery that carries venous blood from the right ventricle of the heart and divides into the right and left pulmonary arteries पर्याय: truncus pulmonalis,
