Question 2

Components of the Respiratory System

Answer 2

(1) nose
(2) pharynx
(3) larynx
(4) trachea
(5) bronchi
(6) lungs.

Question 3

Nose

Answer 3

a supportive framework of bone and cartilage covered with skin externally and it is covered with mucus membranes internally.

Question 4

Breathing In Airway Process

Answer 4

Start out at the External Nares and we go into the Nasal Cavity, from there we go into the Pharynx and there are 3 parts. Then to Larynx, then down into the Trachea, then branch into the left and right bronchi. Then secondary bronchi and then tertiary bronchi and down further.

Question 5

Nostrils

Answer 5

Called the External Nares. They are the two openings on the nose.

Question 6

Cranial Sinuses

Answer 6

Generally adjacent to the walls of the nasal cavity.

Question 7

Frontal Sinuses

Answer 7

Set above the orbits and frontal bone

Question 8

Sphenoid Sinuses

Answer 8

Sets below the Sella Turcica in the Midline

Question 9

Ethmoid Sinuses

Answer 9

Anterior and Laterally to the Sphenoid Sinus. Set in the Ethmoid bone.

Question 10

Maxillary Sinuses

Answer 10

Are the largest of all sinuses. Set in the maxillary bone. Located below the orbits. More commonly affected in sinus infections.

Question 11

Function of the Maxillary Sinuses

Answer 11

Decrease weight of the skull

Vocal Resonance

Question 12

Nasal Cavity

Answer 12

Floor is formed by the Hard Palate and Soft Palate

Question 13

Maxillary Bone

Answer 13

Anterior 2/3 Hard Palate and Posterior 1/3 Soft Palate

Question 14

Palate

Answer 14

Separates the nasal cavity from the oral cavity. And then in the center in the back of the soft palate.

Question 15

Uvula

Answer 15

A pendulous fleshy structure.

Question 16

Concha

Answer 16

Scroll like bony structures of the ethmoid bone.

Question 17

Inferior Nasal Concha Bone

Answer 17

Made up of the lowest Nasal Concha. When they are covered with Mucous Membranes, they are called Terbinates.

Question 18

When Nasal Concha is covered with Mucous Membranes they are called what?

Answer 18

Terbinates

Question 19

Terbinates

Answer 19

Create turbulence as the air passes by on its way into the lungs

Question 20

Functions of Terbinates

Answer 20

Warming up the air, catching the heavier particles by filtering the air before it enters the lungs, it serves to humidify the air.

Question 21

Meatuses

Answer 21

Spaces in between or grooves or deep depressions in between the concha or terbinates

Question 22

Superior, Middle, and Inferior Functions as what?

Answer 22

Serving the same general purpose as the concha to warm the air, filter, and humidify the air.

Question 23

Nasal Septum

Answer 23

Divides the left and right half of the nasal cavity.

Splits the nasal cavity in half. The Nasal Septum consists of the: Perpendicular Plate of the Ethmoid Bone, the Vomer, and cartilage that is anterior.

Question 24

Internal Nares

Answer 24

Opening at the back of the nasal cavity and leave the nasal cavity.
