Across
- 5. A disease of the respiratory system
- 6. Most living organisms use oxygen to release energy from food
- 7. Intercostal muscles and diaphragm change volume and pressure inside the chest
- 10. Within the alveoli by diffusion between air and blood

- 1. Work by forcing water across the filaments
- 2. Their permeable skin makes them susceptible to excessive water loss
- 3. The trachea, bronchus, bronchioles, lungs, air sacs and pleural membranes are all part of this
- 4. Have a large surface area and are well supplied with blood
- 8. Lining of airways become inflamed, fluid builds up, muscles around bronchioles contract constricting airways
