Breath of Life: How Pulmonary Alveoli Function
Storyboard Text
- Glida: 1
- INTRODUCTION TO THE TOPIC
- Don't you worry.I think you have pneumonia that affects a persons pulmonary alveoli.
- i dont feel like i am getting enough oxygen eventhough my breathing is fine!
- Dialogue: Visits the doctor because of a breathing problemAction: Simple drawing showing a person visiting a doctor(the narrator)
- Glida: 2
- RESPIRATORY TRACT
- When we inhale, airflows down the trachea, through the bronchi and bronchioles, and finally into the alveoli.
- wow my insides look like that!!!
- pharynx
- mouth
- inhaled air
- trachea
- lungs
- pulmonary alveoli
- bronchi
- bronchioles
- Dialogue: the respiratory tract which includes the; mouth, pharynx, trachea, lungs, bronchi, bronchioles, and pulmonary alveoli.Action: 1) A noted drawing of the respiratory tract zooming in on the alveoli.2) Adding a crown to the alveoli to show that it is the star of the show.
- Glida: 3
- ROLE OF SURFACTANT
- type II cells synthesize surfactant which is a mixture of phospholipids and proteins that acts to reduce surface tension in the alveoli, thereby inhibiting the collapse of the alveolar wall consequently keeping our lungs stable and working right.
- Dialogue: Explaining how surfactant aids in keeping our lungs healthy.Action:
- Glida: 4
- ROLE OF MACROPHAGE
- we can't also forget the role of macrophages that play a pivitol role in protecting the alveolus
- but what about my sickness
- sorry got carried away i will get you on Treatment ASAP
- Dialogue: macrophages play a big role in protecting the alveoli found in our lungs from any inhaled foreign bacteria and viruses.
- Glida: 5
- GASEOUS EXCHANGE
- here you can how the gaseouse exchange occurs.ITS very exciting!!Dialogue: oxygen passes through two cells-thick counting the alveoli and the capillaries surrounding them into the bloodstream and binds with hemoglobin of red blood cells. Moreover, Carbon dioxide being a cellular metabolism waste is exhaled in a similar manner leaving the body via exhalation.
- Dialogue:gaseous exchange explanation.Action: drawing of the gaseous exchange occuring.
- Glida: 6
- DIFFUSION EXPLAINED
- as you can see here this is how gaseous exchange happens where molecules as oxygen will diffuse from the alveoli to the oxygen-poor blood in the cappillaries to reach the cells.Similarly carbon dioxide diffuses from the blood to the alveoli
- ill leave before it gets congested
- dialogue: Explaining the basics diffusion.Actions: anotating diffusion and a drawing.
