Hey everyone. I don't have other choice than to post it online. So enjoy it here.
Learning outcomes:
Content: to be able to explain lungs structure, gas exchange in the lungs and body tissues, regulation of respiration.
Language: to be able to discuss your intensions to given topic.
1 (individual work). Read the text and make graphic organiser - Mind Map.
“Asthma is common condition that affects the lungs in both adults and children. Approximately 10 percent of adults and 15 percent of children in the Russian Federation suffer from asthma. In addition, asthma is the cause of 80% death in children from 11 to 16 years old. Asthma is a chronic disease characterised by inflammation and fluid collecting in the tissues of the airway, and bronchospasms (constriction of the bronchioles), which can prevent air from entering the lungs. In addition, excessive mucus secretion can occur, which further contributes to airway closing. Cells of the immune system, such as eosinophils and mononuclear cells, may also be involved in infiltrating the walls of the bronchi and bronchioles.
Bronchospasms occur periodically and lead to an “asthma attack.” An attack may be triggered by environmental factors such as dust, pollen, pet hair, or dander, changes in the weather, mould, tobacco smoke, and respiratory infections, or by exercise and stress.”
2 (individual work). Watch the video and answer the questions (https://goo.gl/fdAGhB): Check if you know these words before watching.

- Why is it better that the lungs are spongy rather than empty like a balloon?
- How do you think your breathing and lungs adapt when you're exercising?
