Question

Pulmonary artery arises from______​

Answer 1

Answer:

The main pulmonary artery and the subsequent right and left pulmonary arteries sit within the middle mediastinum. They arise from the right ventricle of the four-chambered heart and transport blood to the lungs.

Answer 2

• The right ventricle of the four-chambered heart gives birth to the pulmonary artery, which carries blood to the lungs.
• The pulmonary arteries convey deoxygenated blood to the lungs for oxygenation from the right side of the heart.
• Between the right side of the heart and the lungs, these arteries function as a conduit.
• The right and left pulmonary arteries give blood flow to their respective lungs, while the lobar, segmental, and sub-segmental arteries of the lungs subdivide into lobar, segmental, and sub-segmental arteries of the lungs, before finally becoming capillaries surrounded by alveoli.
• The pulmonary circulation, which is characterized by high capacitance and low pressure, is excellent for optimum gas exchange.
