Presentation Transcript
slide1. The lungs and breathing<br>
slide2. Learning objectives Define breathing
Label the structure of the respiratory system
Describe some of the effects of smoking on the respiratory system
Explain how muscles enable us to breath Breathing is the process of moving air into and out of the lungs<br>
slide3. Structure and lung diseases Copy the diagram.
Suggest why the trachea is surrounded by rings of cartilage.
Describe how the intercostal muscles and diaphragm help us to breathe in.<br>
slide5. The trachea Ciliated epithelial cell Goblet cell mucus Goblet cells produce mucus
The mucus traps dirt and bacteria
The cilia moves the bacteria up towards the throat where they are swallowed and digested
People with cystic fibrosis produce very thick mucus that is difficult for the cilia to move
Smoking contains chemicals that stop the cilia from moving<br>
slide6. Breathing Complete the cloze procedure against the clock activity
Copy the sentences into your notebook.<br>
slide7. Breathing<br>
slide8. Gaseous exchange Biconcave red blood cell Where is the oxygen concentration highest?
Explain how we maintain a high concentration of oxygen in the lungs.
Suggest the way in which the structure of the alveolus and capillaries ensure rapid diffusion.
How doe the shape of a red blood cell ensure rapid diffusion in and out of the cell?<br>
