Q

Upper Respiratory System

A

Nose and Pharynx

Filters, warms and moistens air

1
Q

The Respiratory System Functions

A

Provide body with oxygen and carry away the carbon dioxide

Gas exchange
Expiration
Inspiration

2
Q

Lower Respiratory System

A

Epiglottis, Larynx, Trachea, Bronchi, Bronchioles, Lungs, and Alveoli

Delivery to blood stream

3
Q

Nose

A

Adjusts incoming air
Filtration by hair and mucosa
Warming and moistening
Ciliated odor receptor cells

4
Q

Pharynx

A

Passage of food and air

5
Q

Tonsils

A

Lymph tissue defense

6
Q

Epiglottis

A

Blocks airway when swallowing food

7
Q

Larynx

A

Adjustable entryway that produces the voice

8
Q

Vocal cords

A

Mucosal folds supported by ligaments

Vibrate when air passes
Pitch from width of opening
Volume from amplitude of vibration

9
Q

Trachea

A

Reinforced tube connecting upper to lower tract

Lined with mucosa producing goblet cells and sweeping ciliated - epithelium

10
Q

Bronchial Tree

A

The trachea divides into right and left bronchi

Branches- bronchioles

11
Q

Lungs

A

Site of gas exchange in the thoracic cavity

12
Q

Alveoli

A

an air cell of the lungs, formed by the terminal dilation of tiny air passageways.

13
Q

Breathing

A

Air enters through the trachea and bronchial tree

It’s a continuous column

14
Q

Muscles control in breathing(inhalation)

A

Increase thoracic cavity size for inhalation
Muscles contract pulling ribs out and diaphragm down
Lungs expand because thoracic cavity sealed
Draws air in

15
Q

Muscles control in breathing(exhalation)

A

Decrease for exhalation
Muscles relax, ribs move and diaphragm up
Lungs contract and air pushed out
Forced exhalation for singing and blowing is more active
Creates air pressure differences

16
Q

Vital capacity

A

The volume of air moved into and out of the lungs is an indication of health

17
Q

Tonsils

A

Lymph tissue defense

18
Q

Epiglottis

A

Blocks airway when swallowing food

19
Q

Larynx

A

Adjustable entryway that produces the voice

20
Q

Vocal cords

A

Mucosal folds supported by ligaments

Vibrate when air passes
Pitch from width of opening
Volume from amplitude of vibration

21
Q

Trachea

A

Reinforced tube connecting upper to lower tract

Lined with mucosa producing goblet cells and sweeping ciliated - epithelium
