8. How can you tell it’s a trachea? تجي سؤال مب بس للفهم
The Epithelium is pseudostratified ciliated columnar
There’s a cartilage
It has 4 layers

9. Bronchi, bronchioles, alveoli
Lungs
Bronchi, bronchioles, alveoli

10. Lung tissue, Bronchus (bronchi)
Red arrow is pointing at the cartilage

11. Lung tissue, Bronchus (bronchi)
Red arrow is pointing at the cartilage

12. Lung tissue, Bronchus (bronchi)
Red arrow is pointing at the cartilage

13. What to mention about bronchi in exam:
Existance of cartilage
The inner bronchial folds

14. Lung tissue, bronchiole
No cartilage present

15. Lung tissue, bronchiole
No cartilage present

16. Lung tissue, bronchiole
No cartilage present

17. Lung tissue, bronchiole
No cartilage present

18. Lung tissue, bronchiole
No cartilage present

19. What to mention about bronchioles in exam:
No cartilage
Bronchiolar folds
Cuboidal cells in terminal bronchioles, and simple squamous in respiratory bronchioles

20. Blank spaces surronded by thin alveolar septum
Lung tissue, Alveoli
Blank spaces surronded by thin alveolar septum

21. Blank spaces surronded by thin alveolar septum
Lung tissue, Alveoli
Blank spaces surronded by thin alveolar septum

22. What to mention about alveoli in exam:
Have thin septums, (the alveolar septum)
Contain type 1 & 2 alveolar cells.

23. Important to mention while naming the slide
Tell if the slide is for a trachea or a lung, then mention the part shown E.g: Lung tissue, Bronchioles
Mention the epithelial tissue
Most important thing to mention is the Pseudostratified ciliated columnar epithelium as it is a special characteristic of respiratory organs.
