question
Question

What is the function the respiratory system?

  • Absorb moisture
  • Breathing
  • Speech
  • All the above
  • B and C
function
Function
  • Life support
    • Exchange CO2 with O2
  • Speech
    • Energy source
question4
Question

What is the thorax?

  • Mouth
  • Lungs
  • Chest
  • Abdomen
  • Throat
question5
Question

What is the function of the alveoli?

  • Exchange N2 with O2
  • Exchange CO2 with O2
  • Exchange CO2 with H20
  • Exchange N2 with H2O2
  • None of these make sense?
question6
Question

Which lung do you think might be larger?

  • Right
  • Left
  • Neither
  • Does it matter
question7

  • Internal intercostals
  • External intercostals
  • Neck muscles
  • Diaphragm
  • Internal respiratory muscle

question14
Question

Can you exhale all the air in your lungs?

True

False

lung volumes capacities
Lung Volumes & Capacities
  • Lung Volumes:
    • TV
    • IRV
    • ERV
    • RV
  • Lung Capacities:
    • VC
    • FRC
    • TLC
question16
Question

The air you normally breath in and out is:

  • VC
  • TV
  • IRV
  • TLC
question17
Question

All the air in you lungs is:

  • VC
  • TV
  • IRV
  • TLC
speech breathing
Speech Breathing
  • More complex than quiet breathing
    • Coordination of breathing with linguistic utterances
      • Appropriate place to inhale
      • Appropriate amount of air to inhale & exhale
      • Prosodic variations
question20
Question

Average number of breaths per minute in an adult:

  • 40-60
  • 20-40
  • 12-18
  • 1-12
  • More than 60
life vs speech breathing
Life

Nose

Inhale 40% of time

Exhale 60% of time

10 % of vital capacity

Muscles of thorax and diaphragm

Speech

Mouth

Inhale 10% of time

Exhale 90% of time

20-25 % of vital capacity

Thoracic and abdominal muscles

Life vs. Speech Breathing

exhale

inhale

exhale

in

slide25

In speech breathing we inhale:

  • 10 percent of the time
  • 40 percent of the time
  • 60 percent of the time
  • 90 percent of the time
  • 50 percent of the time
slide26

In life breathing we exhale:

  • 10 percent of the time
  • 60 percent of the time
  • 40 percent of the time
  • 90 percent of the time
  • 50 percent of the time
measurement devices
Measurement Devices
  • Pneumatochograph used to measure airflow
  • Plethysmograph suit monitors the movements of both the abdomen and ribcage
  • Magnetometer is two coils of wire which generate an electromagnetic field
