ANATOMY

Detailed explanation-1: -The right and left pulmonary arteries divide into 2 lobar branches each, and subsequently into segmental and sub segmental branches. Segmental and sub segmental pulmonary arteries generally parallel segmental and sub segmental bronchi and are named according to the bronchopulmonary segments that they feed (Figure 1).

Detailed explanation-2: -Main pulmonary artery: Your main pulmonary artery exits your heart at your pulmonary valve. It then splits (bifurcates) into your right pulmonary artery and left pulmonary artery. Right and left pulmonary arteries: Your right pulmonary artery goes to your right lung. Your left pulmonary artery goes to your left lung.

Detailed explanation-3: -The pulmonary artery is a blood vessel that comes out of your heart. It splits into two sides, right and left, that carry blood to your lungs where oxygen and carbon dioxide are exchanged.

Detailed explanation-4: -The pulmonary trunk is a short and stout (wide) structure that is about 5 cm in length and 3 cm in diameter, which branches into 2 pulmonary arteries; the left and right pulmonary arteries, which act to deliver deoxygenated blood to its respective lung.

Detailed explanation-5: -The right pulmonary artery is one of the branches of the pulmonary trunk, branching at the level of the transthoracic plane of Ludwig.
