Respritory System

Question 1

Path of air into resp. sys.

Answer 1

• Nasal Passage
• Pharynx
  
  • epiglottis
  • uvula
• Trachea
  
  • cartilage
  • larynx
• Lungs
  
  • branchi
  • bronchioles
  • alveoli

Question 2

Nasal Passage Modification of Air

Answer 2

• Modifies the air
  1. Filters the air (mucus and hair)
  2. Warmer
  3. Moisten

Question 3

Pharynx

Answer 3

Air, and Food and Water

• Epiglottis- covers trechia when swallow
• Uvula- covers nasal passage when swallow

Question 4

Trachea

Answer 4

Lined with Cilia and Mucus

• Cartilage ringes
• Larynx-Voice box

Question 5

Lungs

Answer 5

Branchi- lined with cilia and mucus
Bronchioles
Alveoli- covered with capillaries (so CO2 or O2 can change)

Question 6

Breathing In (Inspiration)

Answer 6

• Enlarge chest cavity (rib muscles contract)
• Diaphram goes down/contracts
• Air pressure decrease
• Air moves into lungs

Question 7

Breathing Out (Experation)

Answer 7

• Decrease in size (Chest Cavity) (rib and diaphram relax)
• Air pressure increase
• Air moves out of lungs
• Control of breathing rate
• Detect CO2
  - Co2+H20—> Carbonic Acid
  - pH of blood (monitors)

Question 8

Tidal Volume (TV)

Answer 8

Normal amount take in w/ normal breath (0.5 L)

Question 9

Inspiratory Reserve Volume (IRV)

Answer 9

Biggest breath you can take (2 L)

Question 10

Expirtory Reserve Volume (ERV)

Answer 10

Pushing out extra air (1 L)

Question 11

Residual Volume (RV)

Answer 11

Air you cannot exhale (1 L)

Question 12

Vital Capacity (VC)

Answer 12

TV + IRV + ERV

Question 13

Total Lung Capacity (TLC)

Answer 13

Takes into account RV; VC+RV
