Flashcards in Lecture 15 - Structural Basis of Respiration Deck (66):
1

topographical?

relating to or representing the physical distribution of parts or features on the surface of or within an organ or organism.

2

Function of the larynx

The larynx acts as an air passageway linking the pharynx with the trachea. It also acts as a sphincter to prevent food from entering the trachea and is the organ of phonation.

3

How many cartilages does the larynx consist of?

 

6

3 unpaired and 3 paired

 

4

How to differentiate bronchioles from bronchi?

 

Bronchi has cartilage.

Bronchioles don't have any cartilage only smooth muscle

 

5

Alveoli?

 

•    Site of gas exchange

•    lined by extremely flattened (squamous) type 1 pneumocytes

–  about 40% of cells but cover >90% of

alveolar surface

•    more-rounded type 2 pneumocytes secrete surfactant

–  about 60% of cells but cover <10% of

alveolar surface

 

–  found esp. at the angles between adjacent septa

–  function as stem cells

 

6

What is the main function of the lungs ?

 

The main function of the lungs is to oxygenate the blood by brining inspired air in close relation to blood vessels and permitting gaseous exchange.

 

7

What is the chief muscle of respiration?

 

The diaphragm
