Study Notes
Pulmonary Vessels
- Pulmonary Artery: Transports deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.
- Pulmonary Vein: Carries oxygenated blood from the lungs back to the left atrium of the heart.
Alveolar Structures
- Alveolus: Tiny air sacs in the lungs where gas exchange occurs; they increase surface area for efficient oxygen and carbon dioxide diffusion.
- Capillaries: Microscopic blood vessels surrounding alveoli; facilitate the exchange of gases between the air in the alveoli and the blood.
- Alveolar Ducts: Tube-like structures leading from the bronchioles to the alveolar sacs; enhance airflow regulation within the lung.
- Alveolar Sacs: Clusters of alveoli at the end of alveolar ducts; function as the terminal air spaces where gas exchange predominantly occurs.
