pulmonary artery

This will end dividing the aorta from the pulmonary trunk.

It runs in a common pericardial sheath with the pulmonary trunk.

Instead of coming from the pulmonary trunk, supply develops from the aorta and other systemic arteries.

The semi-lunar pulmonary valve is located between the right ventricle and the pulmonary trunk.

Between it and the pulmonary trunk is a network of autonomic nerve fibers, the cardiac or aortic plexus.

The truncus arteriosus gives rise to the ascending aorta and the pulmonary trunk.

The role of the right ventricle is to pump deoxygenated blood to the lungs through the pulmonary trunk and pulmonary arteries.

These are located at the base of both the pulmonary trunk (pulmonary artery) and the aorta, the two arteries taking blood out of the ventricles.

In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle.

These two blood vessels twist around each other, so that the aorta starts out posterior to the pulmonary trunk, but then twists to its right and anterior side.

In this condition, the embryological structure known as the truncus arteriosus fails to properly divide into the pulmonary trunk and aorta.

The cardiac skeleton consists of four dense bands of dense connective tissue that encircle the bases of the pulmonary trunk, aorta, and heart valves.

Cardiac valves play a crucial role in ensuring the unidirectional flow of blood from the atrium to the ventricles, or the ventricle to the aorta or pulmonary trunk.

From autologous arterial-derived cells and fibrin scaffold, tissue engineered heart valves are formed, then mechanically conditioned and transplanted into the pulmonary trunk of the same animals.

The conus arteriosus is also called the infundibulum, and it is the entrance from the right ventricle into the pulmonary artery and pulmonary trunk.

The conus arteriosus is a conical pouch formed from the upper and left angle of the right ventricle in the chordate heart, from which the pulmonary trunk arises.

It receives deoxygenated blood from the right atrium via the tricuspid valve, and pumps it into the pulmonary artery via the pulmonary valve and pulmonary trunk.

Theory suggests that an ectopic focus, usually within the pulmonary trunks, competes with the sinoatrial node for electrical control of the atrial chambers to the detriment of atrial myocardial performance.

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 CNCCs are required for the formation of the aorticopulmonary septum (APS) that separates the cardiac outflow into the pulmonary trunk and the aorta in normal heart development.

Silk marking sutures may be placed in the pulmonary trunk at this time, to indicate the commissure of the aorta to the neo-aorta; alternatively, this may be done later in the procedure.

This happens at two areas: where the aorta and pulmonary trunk leave the heart and where the superior vena cava, inferior vena cava and pulmonary veins enter the heart.

The aortic arch loops over the right pulmonary artery and the bifurcation of the pulmonary trunk, with which it remains connected by the ligamentum arteriosum, a remnant of the fetal circulation that is obliterated a few days after birth.

Right heart is a term used to refer collectively to the right atrium and right ventricle of the heart; occasionally, this term is intended to reference the right atrium, right ventricle, and the pulmonary trunk collectively.

Tetralogy of Fallot with pulmonary atresia (pseudotruncus arteriosus) is a severe variant in which there is complete obstruction (atresia) of the right ventricular outflow tract, causing an absence of the pulmonary trunk during embryonic development.
