| Function | The first cervical vertebra that supports the skull. Allows nodding movements (flexion and extension) of the head at the atlanto-occipital joint. | The primary organs of gas exchange, allowing oxygen to enter the blood and carbon dioxide to be expelled. The total surface area of the alveoli is approximately 70 square meters, … |

Congenital anomalies include atlas assimilation (occipitalization). | Lung cancer is the leading cause of cancer death. Pneumonia is inflammation of the alveoli. Chronic obstructive pulmonary disease (COPD) includes emphysema and chronic bronchitis. Pulmonary embolism is a life-threatening … |
