Divides into right and left bronchi at T-5
Consists of 16-20 rings

Oblique and horizontal fissures in the Right

Oblique fissure in the left lung only

Question 21

What are the respiratory bronchioles?

Answer 21

microscopic branches of terminal bronchioles

Question 22

Define alveolar ducts:

Answer 22

Subdivisions of respiratory bronchioles

Question 23

What are alveolar sacs:

Answer 23

2 or more alveoli that share a common opening to the alveolar duct

Question 24

Define Alveoli:

Answer 24

cup shaped outpouching of an alveolar sac.

The walls of the alveoli consist of alveolar cells which are simple squamous epithelial cells

Question 25

What are the surfactant cells responsible for?

Answer 25

• A mixture of phospholipids and lipoproteins that reduce the collapse of the alveoli
• secrets alveolar fluid which keeps the surface between the cells and the air moist
