25
takes in air
Nasopharynx
26
extends from uvula to epiglottis, takes in food, drink, and air
Oropharynx
27
extends from epiglottis to esophagus, food and drink pass through
Laryngopharynx
28
“little grape” extension of soft palate
Uvula
29
aids in defending against infections
Pharyngeal tonsil
30
located in the anterior throat and extends from the base of the tongue to the trachea and consists of 9 cartilages
LARYNX
31
largest piece of cartilage and called Adam’s apple
Thyroid cartilage
32
piece of cartilage and flap that prevents swallowed materials from
Epiglottis
33
false vocal cords
Vestibular Folds
34
source of voice production and air moves past them, they vibrate, and sound is produced
Vocal Cords
35
"Windpipe" Consists of 16 to 20 C-shaped pieces of cartilage called tracheal rings
Trachea
36
Divides into right and left main (primary) bronchi in the lungs at the carina * Lined with cilia * Contain C-shaped pieces of cartilage
Bronchi
37
Structures become smaller and more numerous from primary bronchi to alveoli.
Tracheobronchial Tree
38
- the smooth muscle relaxes, making the bronchiole diameter larger.
Bronchodilation
39
the smooth muscle contracts, making the bronchiole diameter smaller
Bronchoconstriction
40
contraction of terminal bronchioles leads to reduced air flow
Asthma attack
41
The sites of external respiration and it was describe as small air-filled sacs where air and blood
Alveoli
42
have a few attached alveoli.
Respiratory bronchioles
43
arise from the respiratory bronchioles and open into alveoli.
Alveolar ducts
44
are chambers connected to two or more alveoli at the end.
Alveolar sacs
45
In lungs where gas exchange between air and blood occurs, Formed by walls of alveoli and capillaries
Respiratory Membrane
46
Primary organ of respiration
Lungs
47
the space enclosed by the thoracic wall and the diaphragm
Thoracic cavity
48
a sheet of skeletal muscle separating the thoracic cavity from the abdominal cavity
Diaphragm
49
Oxygenated blood has passed through the lungs and picked up _____________
O2/Oxygen
50
Deoxygenated blood has passed through the tissues and released some of its ______
O2/Oxygen
51
Pulmonary arteries carry ________blood to pulmonary capillaries
deoxygenated
52
Blood becomes ________ and returns to the heart through pulmonary veins.
oxygenated
53
space around each lung
Pleural cavity
54
double-layered membrane around lungs
Pleura
55
membrane that lines thoracic cavity
Parietal pleura
56
membrane that covers lung’s surface
Visceral pleura
57
the process of moving air in and out of the lungs
Ventilation
58
increase the volume of the thoracic cavity
Muscles of inspiration
59
decrease thoracic volume by depressing the ribs and sternum.
Muscles of expiration
60
When the volume of a container increases the air pressure _________.
decreases
61
When the volume of a container decreases air pressure __________.
Increases
62
* Diaphragm descends and rib cage expands * Thoracic cavity volume increases, pressure decreases * Atmospheric pressure is greater than alveolar pressure * Air moves into alveoli (lungs)
Inspiration
63
* Diaphragm relaxes and rib cage recoils * Thoracic cavity volume decreases, pressure increases * Alveolar pressure is greater than atmospheric pressure * Air moves out of lungs
Expiration
64
Blood returning from tissues and entering alveoli in the lungs has a _______ partial pressure of O2 and a ________ partial pressure of CO2 than the air in the alveoli.
-lower -higher
65
Blood traveling from the lungs and through capillaries in the tissues has a ______ partial pressure of O2 and a _______ partial pressure of CO2 than the interstitial fluid.
-higher -lower
66
* Once O2 and CO2 enter the blood they interact with components that increase their _________.
solubility
67
CO2 reacts with water to form ________.
carbonic acid
68
Carbonic acid dissociates into a _________ and ___________ .
hydrogen ion and a bicarbonate ion
69
Carbonic anhydrase (RBC) increases rate of CO2 reacting with water As CO2 levels increase, blood pH decreases
