Flashcards in Respiratory System Deck (22):
1

Name 3 functions of the respiratory system:

  1. Exchange of O2 and CO2
  2. Filters, moistens and warms incoming air
  3. Plays a role in pH buffering of the blood

2

Name the 4 Processes of respiration:

  1. Ventilation
  2. External Respiration
  3. Transport of Gases
  4. Internal Respiration

3

Name the 3 Upper Respiratory Structures:

  1. Nose
  2. Pharynx
  3. Larynx

4

List 3 structures found in the nose:

  1. Nasal cavity
  2. Nasal conchae
  3. Paranasal sinuses

5

Name the 3 regions of the Pharynx:

  1. Nasopharynx
  2. Oropharynx
  3. Laryngopharynx

6

Name 2 charictoristics of the Larynx:

  1. made up of cartilage
  2. contains vocal folds

7

Name the 4 Lower Respiratory Structures:

  1. Trachea (
  2. Bronchi
  3. Bronchioles
  4. Alvioli

8

Describe the 4 structural charictoristics of the surface of Trachea: 

  1. Composed of "Sudo Stratified columnar epithelium"
  2. C shaped cartalage
  3. Has Cilia
  4. Goblet cells

9

Describe the 2 main charictoristics of Bronchi:

  1. contains cartilage
  2. contains mucus cells

10

Name the defining charictoristic of Bronchioles:

Smooth muscle

11

Name the function and 3 functional charictoristics of Alveoli:

function = gas exchange

  1. contains a Resporatory membrain
  2. contains pulmonary capillaries
  3. is composed of Simple Squamous Epithelium

12

Describe the lobes of the lungs left vs. right

  • 3 lobes on the right
  • 2 lobes on the left

13

Name the 2 serous membranes that suround the lungs.

  1. Visceral Plura (inner membrane)
  2. Parietal Plura (outer membrane)

14

Name the two main muscles that control breathing:

  1. diaphragm
  2. intercostals

15

Name to charictoristic of breathing:

  1. contraction and relaxation of muscles
  2. changes in pressure

16

Describe Tidal Volume (TV)

  • the amount of air exchanged during a resting breath ~ 500mL

17

Describe Inspiratory Reserve Volume (IRV)

  • the amount of air inhailed above tidal volume ~ 3100mL

18

Describe Expiratory Reserve Volume (ERV)

  • the amount of air exhailed below tidal volume ~ 1200mL

19

Describe Vital Capacity (VC)

  • The amount of air exchanged during a forceful breath ~ 4800mL
  • VC = TV + ERV + IRV
  • volume based on hight, age, and gender

20

Residual Volume (RV)

  • the amount of air always present in the lungs (amount can't be measured in health  adults), but ~ 1000mL on average

21

Total Lung Capasity (TLC)

  • The total amount of air possible in the lungs
  • TLC = Vital Capasity + Residual Volume

22

Forced Expiratory Volume (FEVtime)

  • The amount of air exhailed during a forceful breath in 1 second ~ 85% of VC
