Flashcards in Respirartory System Deck (19):
1

Respiratory System

Responsible for the gas exchange that occurs btw the atmosphere and the blood stream

2

Nasal Cavities

Air first enter here

3

Pharynx

Air passes from the nasal cavitity to here
Passage way that transports liquids and solids to the digestive system

4

Larynx

(the voice box)
Air passes from the pharynx to here
Composed on nine hyaline and elastic cartilages

5

Thyroid Cartilage

Largest and most prominent cartilage of the larynx

6

Trachea

Transports air from the larynx into the thoracic cavity

7

Right and Left primary Bronchi

Located Fifth thoracic vertebra
The trachea branches here to form and thus the right and left lung
Hyaline cartilages extend down to open the airways

8

Left Lung

Consists of two lobes (Upper and Lower)
Separated by an oblique Fissure
Contain a cardiac notch, seen on the medial surface where the heart is

9

Right lung

Contains three lobes (Upper, middle, and lower)
Separated by an oblique fissure and the horizontal fissure
Difference in size is due to the heart

10

Right primary bronchus

Larger in diameter and more vertical than the left
Food particle have a tendency to drop into here than the left side

11

Secondary Bronchi

Right and Left Primary bronchi branch into 5 of these for each lobe.
Further divide into ten tertiary (Segmental) bronchi on each side

12

Tertiary Bronchi

Accompanying pulmonary vessels each supply a bronchopulmonary segment.
Allows for surgeons to only remove this part on an individual over the lobe or an entire lung

13

Mediastinum

Region btw the lungs that contains the heart, thymus gland, lower segment of the trachea, part of esophagus and portions of the great vessels.
extends from the diaphragm, past the medial third of the clavicle on into the lower neck.

14

Apex of the lung

Portion of the lung that reaches beyond the clavicle into the neck

15

Pleura

Covers the lung, serous membrane friction less movement of the underlying organs

16

Parietal Pleura

Outer layer
Lines the rib cage, covers the thoracic surface of the diaphragm and surround the mediastinum

17

Visceral Layer

Inner Layer
Covers the lung surfaces

18

Mediastinum

Middle

19

Apex
