ligamentum arteriousum
The ligamentum arteriosum (Latin: arterial ligament) is a small ligament that is the remnant of the ductus arteriosus formed within three weeks after birth. At the superior end, the ligamentum attaches to the aorta—at the final part of the arch of aorta (the isthmus of aorta) or the first part of the descending aorta.
right and left pulm. arteries form
the pulm trunk
pulm arteries
take deoxygnated blood away from the heart and to the lungs- only exception do the opposite
base of the pulm trunk is a derivative of
the old ventral aorta, where its right and left branches are derived from the sixth aortic arch
coronary arteries
supply the heart muscle with oxygenated blood
pulm veins
bring oxygen. blood into the heart from the lungs- usually four pulm veins in humans
