Answer 10

Nose, Nasal passage, nasopharynx, larynx into trachea

Paranasal sinuses

Question 11

Contains resident flora , air is warmed and moistened as passed through nasal cavity (when air passed through the mouth, it is not warmed, moistened or filtered)

Answer 11

Nose and Nasal passage of the upper respiratory tract

Question 12

Frontal, ethmoid, sphenoid, and maxillary (named according to the bones in which they are located)

Answer 12

Paranasal sinuses- Upper respiratory tract

Question 13

Lined by the respiratory mucosa, pseudostratified columnar epithelium which has goblet cells and cilia; mucous traps debris and cilia sweeps it away

Answer 13

Paranasal sinuses- Upper respiratory tract

Question 14

Posterior wall of nasopharynx contains pharyngeal tonsils (adenoids-lymphoid tissue)

Answer 14

Nasopharynx

Question 15

Name the parts of the Lower Respiratory tract

Answer 15

Trachea- windpipe
Begins at inferior border of larynx, ends at level of T5 where it bifurcates. (divides into left and right bronchi) This bifurcation radiograhically is called the carina and corresponds to the level of T4 and T5.

Air proceeds from the trachea to the right and left bronchus

Right bronchus- larger and straighter so more likely destination for any aspirated material

Bronchus- enters lung at hilum then branches to form bronchial tree; bronchi become smaller cartilage rings diminish and smooth muscle increases allows contraction and relaxation

Question 16

What is the trachea composed of?

Answer 16

rings of cartilage, smooth muscle and elastic tissue

Question 17

What does the Thorax consists of?

Answer 17

Ribs, Vertebrae, Sternum, Providing rigid protection for the lungs
12- pair of ribs with the last two as floating

Question 18

Coned shape structures positioned on each side of the heart

Answer 18

Lungs

Question 19

Located in the center of the chest which contains heart, major blood vessels, esophagus and trachea

Answer 19

Mediastinum

Question 20

What contains macrophages which remove foreign debris that penetrates them

Answer 20

Alveoli

Question 21

Dome shaped muscular diaphragm forms the inferior boundary

Answer 21

Diaphragm

Question 22

How many lobes is the right heart divided into?

How many lobes is the left heart divided into?

Answer 22

3

2

Question 23

What are the coverings of the lung?

Answer 23

Pleural membrane- double wall sac
Visceral Pleura- Attached to outside of lung
Parietal Pleura- Attached to the chest wall and diaphragm
Pleural Cavity or Space- separates visceral and parietal pleura, contains small amount of fluid

Answer 30

Chest x-ray (75% of the natural history of the disease has already occurred at the time of the chest x-ray) CT (shows what other structures affected) PET Laboratory studies Surgical procedure
