Flashcards in Anatomy final part 2 Deck (13):
1

Upper respirsatory

Nose

2

Nasal Cavity

1. Lined with Respiratory mucosa
a. Contains large nose hairs called Vibrissae (help trap particles and keep them out of your lungs)
b. Vibrissae are lined with mucus that help entrap large particles
c. Preventing them from getting too deep into the lower respiratory
tract
d. Smaller particles are entrapped by the nasal mucosa within the
nasal cavity
e. Most are moved down toward the throat by the beating cilia of
the mucosa layer and swallowed (

3

Paranasal Sinuses

1. Ethmoid
2. Sphenoid
3. Frontal
4. Maxillary
5. Functions
a. Decreases the weight of the skull
b. Increases voice resonance
c. Insulates eyes and dental roots from extreme temperature
fluctuations
d. Warms and humidifies the air that is inhaled

4

Pharynx (Throat)

1. Five inches long
2. Divided up into three regions a. Nasopharynx
b. Oropharynx
c. Laryngopharynx
i. Contains the tonsils
1. Tonsils: masses of lymphoid tissue

a. Adenoids: in the nasopharynx (snoring issues)
b. Palatine: in the oropharynx (visible)

5

Larynx (voice box)

1. Made up of several pieces of cartilage, the largest being the Thyroid
cartilage “Adam’s apple”
2. Vocal cords: 2 fibrous bands that stretch across the larynx
a. Glottis: the space in between the cords
b. Epiglottis: cartilage flap which covers the glottis during
swallowing and prevents food/liquid from entering the trachea

6

Trachea (wind pipe)

1. 4.5 inches long
2. Made up of cartilaginous rings

7

Lungs

1. Left lung has 2 lobes
2. Right lung has 3 lobes
-Primary Bronchi: 2 left and right (cartilage)
-Secondary Bronchi (cartilage)
-Bronchioles: smooth muscle
-Alveolar Sacs: made up of alveoli (which are the smallest functional units of respiration) simple squamous epithelial (really thin; very efficient) and very vascular for oxygen/carbon dioxide exchange

8

Pleura

-The lining around the lungs (for protection)
-Lubricates the lung during inhalation
-Two linings
i. Parietal pleura
ii. Visceral pleura

9

Asthma

Etiology
1. Bronchospasm (smooth muscle of the bronchioles)

10

Caused by

allergies, irritants, exercise, stress

11

Treatment

1. Bronchodilator (inhaler)
2. Steroids (prednisone)

12

Prognosis

1. 5,000­-6,000 deaths a year

13

Characterized by

wheezing, coughing, and musical pipe rails (sound in lungs when breathing)
