Lung Terminology (EXAM 1)

Question 1

Respiratory system as functional unit

Answer 1

Lungs (pulmonary apparatus)
Rib cage (thoracic wall)
Abdomen (Abdominal wall and viscera)

all 3 are a functioning, single unit, hip to lips!

Question 2

Vital capacity (VC)

Answer 2

Maximum useable volume of air that can be inhaled from rest and exhaled to end of breath
i.e. take deepest breath from rest and breathe it ALL OUT

Question 3

Resting Volume

Answer 3

Amount of air that you can exhale from resting position (resting = end of exhale)
i.e. how much air you have left after normal exhale; inhale, exhale, exhale further
40% of vital capacity
Includes the residual volume

Question 4

Tidal Volume

Answer 4

Amount of air inhaled/exhaled during activity
activity dependent
resting tidal volume: how much air you inhale/exhale at rest

Question 5

Inspiratory Reserve Volume

Answer 5

Amount of air that can be inhaled beyond any 1 tidal volume

Question 6

Expiratory Reserve Volume

Answer 6

Amount of air that can be exhaled beyond any 1 tidal volume
Technically the resting volume without the residual volume

Question 7

Residual Volume

Answer 7

Amount of air left in lungs after max exhalation
not used for breathing, not included in vital capacity, and cannot be rid of
