Yes or No? What is the normal TLC? 1. 2. Give 2 reasons why someone's Tidal volume would not be within the 500 mL normal range? 3. How is the functional residual capacity measured? 4. What are 2 differences between the inspiratory reserve volume and inspiratory sapacity 5. What is the difference between an obstructive vs a restrictive respiratory disorder/disease?

Answer 1

(A) NASOPHARYNX :-
1. Normally Carries :- Air
2. Tissue type :- stratified squamous epithelium and pseudostratified epithelium.
3. Cause of tissue :- it protects the outer nasal pathway and purify air.

(B) OROPHARYNX:-
1. Normally Carries :- Air and food
2. Tissue type :- non-keratinised squamous stratified epithelium.
3. Cause of tissue :- protect and strengthen the oral cavity.

(C) LARYNGOPHARYNX:-
1. Normally Carries :- Air and food
2. Tissue type :- stratified squamous epithelium
3. Cause of tissue :- multiple layer of cells protect and strengthen.
