This makes its appearance in three portions. 1 Two distal ridge like thickenings project into the lumen of the tube these increase in size, and ultimately meet and fuse to form a septum, which takes a spiral course toward the proximal end of the truncus arteriosus . It divides the distal part of the truncus into two vessels, the aorta and pulmonary artery, which lie side by side above, but near the heart the pulmonary artery is in front of the aorta . 2 Four endocardial cushions appear in the proximal part of the truncus arteriosus in the region of the future semilunar valves the manner in which these are related to the aortic septum is described below. 3 Two endocardial thickenings anterior and posterior develop in the bulbus cordis and unite to form a short septum this joins above with the aortic septum and below with the ventricular septum. The septum grows down into the ventricle as an oblique partition, which ultimately blends with the ventricular septum in such a way as to bring the bulbus cordis into communication with the pulmonary artery , and through the latter with the sixth pair of aortic arches while the left ventricle is brought into continuity with the aorta, which communicates with the remaining aortic arches.

The total length is about 5 cm in length. Components The aortic root is the portion of the ascending aorta beginning at the aortic annulus and extending to the sinotubular junction. Between each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses . The sinotubular junction is the point in the ascending aorta where the aortic sinuses end and the aorta becomes a tubular structure. Relations At the union of the ascending aorta with the aortic arch the caliber of the vessel is increased, owing to a bulging of its right wall. This dilatation is termed the bulb of the aorta , and on transverse section presents a somewhat oval figure.

In humans there are four pulmonary veins, two from each lung. They carry Oxygenation medical oxygenated blood, which is unusual since almost all other veins carry deoxygenated blood. Types They are four in number, two from each lung, and are destitute of valves. They are right inferior right superior left inferior left superior Path They commence as a network of capillary capillaries on the walls of the alveoli i.e. air sacs , where they are continuous with the capillary ramifications of the pulmonary artery . The capillaries on each alveolus join together and form one vessel, which upon uniting form a single trunk for each lung lobe three for the right, and two for the left lung. The vein from the middle lobe of the right lung generally unites with that from the upper lobe so that ultimately two trunks from each lung are formed. The individual trunks perforate the fibrous layer of the pericardium and open separately into the upper and back part of the left atrium . Occasionally the three veins on the right side remain separate, and not infrequently the two left pulmonary veins end by a common opening into the left atrium. Therefore, the number of pulmonary veins opening into the left atrium can vary between three and five in the healthy population.
