Respiratory Exam

Question 1

Three divisions of pharynx

Answer 1

Oropharynx nasopharynx larygopharynx

Question 2

What separates the left and right nasal passages

Answer 2

Nasal septum

Question 3

What is the pressure in the thorax; how does it aid in resp.

Answer 3

Negative intrathoracic pressure allows lungs to follow movements of thoracic wall and diaphragm

Question 4

Functions of nasal passages

Answer 4

Warming, filtering, and humidifying air

Question 5

Internal resp

Answer 5

Exchange of CO2 and O2 between the systemic capillaries and all the cells and tissues of the body

Question 6

External resp

Answer 6

Exchange of CO2 and O2 between inhaled air and the blood flowing through the pulmonary capillaries (doesn’t go past lungs)

Question 7

Hilus

Answer 7

Small, well defined area on medial side of lungs (where air blood lymph and nerve supply leave lungs)

Question 8

Partial pressure of gases

Answer 8

% of each individual gas of a mix of gases

Question 9

What type of mechanical control system does the respiratory system have that sets limits on routine inspiration and expiration

Answer 9

Stretch receptor

Question 10

Functions of larynx

Answer 10

Voice production
Prevention of inhalation of foreign matter
Control of airflow to and from the lungs

Question 11

What separates the nasal cavity from the oral cavity

Answer 11

Hard and soft palate

Question 12

Hypoxia

Answer 12

Decreased o2 of blood

Question 13

Residual volume

Answer 13

Volume of air remaining in the lungs after the max expiration

Question 14

Tidal volume

Answer 14

Volume of air inspired and expired during one breath

Question 15

Minute volume

Answer 15

Volume of air inspired and expired during one minute of breathing

Question 16

Diaphragm

Answer 16

Dome sheet of skeletal muscle

Question 17

What type of epithelium lines the alveoli

Answer 17

Answer 23

Abdominal muscles

Question 24

Where are the chemical receptors that monitor respiration found and what do they measure

Answer 24

Croatia artery and aorta

measures CO2 content, pH, O2 content

Question 25

Alveoli

Answer 25

Thin, tiny walled sacs in lungs where o2 and CO2 are exchanged surrounded by capillaries

Question 26

Sinuses

Answer 26

Hollow cavities in nasal bone

Question 27

Primary function of the respiratory system

Answer 27

Swapping oxygen for CO2

Question 28

Secondary functions of respiratory system

Answer 28

Voice production, body temp regulation, acid-base balance regulation, sense of smell

Question 29

Thin membrane that lines the thoracic cavity and organs

Answer 29

Plaura

Question 30

What happens to the bronchial smooth muscle during intense physical activity

Answer 30

Relaxes/dilates ; which helps a great amount of air back and forth to the alveoli

Question 31

What structure are located in the mediastinum

Answer 31

Heart, lungs, esophagus,

Question 32

When swallowing how is food prevented from going into the trachea

Answer 32

Epiglottis

Question 33

How are CO2 and pH related

Answer 33

Too little O2 = low pH Too much o2 = increase in pH

Question 34

What physiological structure does the trachea have to prevent it from collapsing

Answer 34

C-shaped rings

Question 35

Breathing is controlled by what structure

Answer 35

Medulla oblongata

Question 36

Alveolar has exchange

Answer 36

High levels of O2 in air SIMPLE diffuses into blood where level is lower, high level of CO2 in blood diffuses into air where level is lower
