The global impact of respiratory disease. Normal Lung Function Breathing is taken for granted by most people. Lungs Function. pumping blood through your lungs (perfusion) Although tiny, the alveoli are the center of your respiratory system’s gas exchange.

The heart pumps oxygen-depleted…, The main pulmonary artery is responsible for transporting oxygen-depleted blood away from the heart and back toward the lungs. The Human Lungs Function and Parts – As one of the vital organs in the body, human lungs serve as the primary respiratory organ.However, in addition to helping us inhale the air, other lung function is not less important to the body. Medline Plus. These can be signals to the body that there is an infection or irritant that should be avoided or treated.

The lungs are the main part of the respiratory system. Lungs Structure and Function. In the lungs, air is diverted into smaller and smaller microscopic branches called respiratory bronchioles, which connect to the alveolar ducts. Gas exchange occurs in the alveoli deep in the lungs. The function of the pulmonary circulation is to aid in gas exchange. When you breathe, air enters through your mouth and nose and travels: Each alveolus is covered by a net of tiny blood vessels called capillaries.
