Changes

The air in the alveoli is renewed regularly, thanks to the [[Ventilation - Anatomy & Physiology|ventilation]] process. Gas Exchange in the [[Lungs - Anatomy & Physiology|lungs]] takes place between the blood in the capillary network surrounding the alveoli, and the air in the alveoli itself.

All of the blood from the [[Structure of the Heart - Anatomy & Physiology#Right Ventricle|Right Ventricle]] flows through the capillary network which surrounds the alveoli. Another set of pulmonary capillaries recieve small amounts of arterial blood from the [[Structure of the Heart - Anatomy & Physiology#Left Ventricle|Left Ventricle]], via the '''Bronchial Arteries'''. These capillaries provide oxygen and nutrients to the [[Lungs - Anatomy & Physiology|lung] tissue.
