Structure of Lungs
- Ribs surrounding thorax, forming RIB CAGE
- Diaphragm lies across bottom of thorax
- Lungs are attached to inside of rib cage & diaphragm by PLEURAL MEMBRANES
- Ribs can be moved by the INTERCOSTAL MUSCLES (which lie between them)
- Trachea divides into TWO tubes, called BRONCHI (one leading into each)
- Bronchi highly branched, giving many pathways for air to enter/leave lung.
- Bronchioles end in clusters of tiny air sacs called ALVEOLI, this is where gas exchange occurs.
