Functionally, what is the most important structure of the lungs?
Alveoli
Trachea
Bronchi
Bronchoilis
What muscles are used for inspiration?
Diaphragm only
Intercostals Only
Diaphragm and intercostals
No muscles are needed- based on atmospheric pressure
Tidal volume is
Total volume of air inspired
Total volume of air expired
Normal breathing volume
Total capacity of the lungs
Eupnea means:
Increase breathing rate
"Good" normal breathing
Labored breathing
Slow shallow breathing
CO2 is carried in your blood mostly on/ in:
Plasma
Bicarbonate ions
Hemoglobin
White blood Cells
External respiration happens between
Alveoli and blood
Bronchioles and blood
Blood and cells
Hemoglobin and oxygen
What is the most important stimulus to breathing?
Oxygen levels
Carbon levels
Carbon dioxide levels
Hemoglobin levels
Exchange of oxygen and carbon dioxide is by
Diffusion
Osmosis
Active Transport
Use of protein transports
What area contains the highest level of Oxygen?
Alveolar air
Cellular fluid
Capillary blood
Pulmonary artery blood
Vital capacity is:
Total air that is available in the lungs
Normal capacity of breathing in and out
Maximum air a person can inhale and exhale
Maximum air a person can just inhale
Internal respiration happens:
Between blood and cells
Between lungs and the blood
Between the heart and the lungs
Between cells and other cells
During exhalation all happens except:
Air enters the alveoli
Ribs collapse back together
Diaphragm is pulled upwards
Pressure within the chest cavity is increased
