Pulmonary Arteries:These are large blood vessels that transport deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.
Pulmonary Veins:Vessels that carry oxygen-rich blood from the lungs back to the left atrium of the heart, completing the pulmonary circuit.
Gas Exchange:The process by which oxygen is absorbed into the bloodstream and carbon dioxide is released from it, primarily occurring in the lung's alveoli during breathing
