Success Criteria: You can describe how some cells form tissues and tissues form systems.
Today we finished up a worksheet about how cells, tissues, and organs are organized into systems.
Handout: Cells Working Together Worksheet
Then we discussed the respiratory system.
Handout: Respiratory System
Why do we need to breath? It's all about getting oxygen in and carbon dioxide out. We watched these videos of some extreme breath holding:
Most people who have not trained for this kind of stunt will experience some brain damage after 3-5 minutes, so don't try this!
The respiratory system begins at your nose hairs,
then onto through your larynx, trachea and into your lungs. If you have some kind of injury or disease, you might need to get a tracheostomy to help you breath through a tube in your throat.
We highlighted important parts of the notes such as alveoli, capillaries and gas exchange. Make sure you know what all these parts are and how they work.
Finally we continued working on your mitosis posters.
