Question l.jpgSlide 2

Question

What is the function the respiratory system?

  • Absorb moisture

  • Breathing

  • Speech

  • All the above

  • B and C

Function l.jpgSlide 3

Function

  • Life support

    • Exchange CO2 with O2

  • Speech

    • Energy source

Question4 l.jpgSlide 4

Question

What is the thorax?

  • Mouth

  • Lungs

  • Chest

  • Abdomen

  • Throat

Question5 l.jpgSlide 5

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?

  • Neck muscles

  • Diaphragm

  • Internal respiratory muscle

Basic components l.jpgSlide 8

Basic Components

  • Thoracic cavity

    • Rib cage

    • Spinal column

  • Neck

    • Muscles

    • Pharynx

    • Larynx

True

False

Lung volumes capacities l.jpgSlide 15

Lung Volumes & Capacities

  • Lung Volumes:

    • TV

    • IRV

    • ERV

    • RV

  • Lung Capacities:

    • VC

    • FRC

Question16 l.jpgSlide 16

Question

The air you normally breath in and out is:

  • VC

  • TV

  • IRV

  • TLC

Lung volumes and vital capacity l.jpgSlide 18

Lung Volumes and Vital Capacity

Speech breathing l.jpgSlide 19

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 l.jpgSlide 20

Question

  • 40-60

  • 20-40

  • 12-18

  • 1-12

  • More than 60

Life vs speech breathing l.jpgSlide 24

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

in

Slide25 l.jpgSlide 25

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 l.jpgSlide 26

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
