Product Description
This powerpoint presentation covers 'Topic 6.4 - Gas Exchange' in the NEW IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note.

The topic has been divided into 3 sections:

     • A - Ventilation
     • B - Alveoli
     • C - Lung Cancer & Emphysema

The presentation itself contains minimal information as it is intended to be used with teacher guidance. There are sometimes 'Video' throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.

Suggested Use:

I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the IB Bio Understandings. The remaining class time is spent reinforcing the knowledge or working on activities, written test practice, or nature of science.

**These presentations are based on the IB Biology Course Guide and do not follow any textbook

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

==============================

Learning Objectives:

U1: Ventilation maintains concentration gradients of oxygen and carbon dioxide between air in alveoli and blood flowing in adjacent capillaries.
U2: Type I pneumocytes are extremely thin alveolar cells that are adapted to carry out gas exchange.
U3: Type II pneumocytes secrete a solution containing surfactant that creates a moist surface inside the alveoli to prevent the sides of the alveolus adhering to each other by reducing surface tension.
U4: Air is carried to the lungs in the trachea and bronchi and then to the alveoli in
bronchioles.
U5: Muscle contractions cause the pressure changes inside the thorax that force air in and out of the lungs to ventilate them.
U6: Different muscles are required for inspiration and expiration because muscles only do work when they contract.
A1: Causes and consequences of lung cancer.
A2: Causes and consequences of emphysema.
A3: External and internal intercostal muscles, and diaphragm and abdominal muscles as examples of antagonistic muscle action.
