Respiratory Structures Respiration Respiratory Functions Spirometry Respiratory Health
100
What are the bronchi
The branches of the trachea that go into each lung
100
What is a moist environment, large surface area, and a concentration gradient
The 3 requirements for respiration
100
What is contraction
During inhalation, the rib muscles and diaphragm undergo this process
100
What is tidal volume
The amount of air in and out of lungs during normal breathing
100
What is laryngitis
An inflammation of the larynx
200
What is the nasal passage
The air is filtered, cleaned, warmed, and moistened here
200
What is external respiration
The gas exchange between alveoli (air) and capillaries (blood)
200
What is a decrease
During exhalation, the volume experiences this
200
What is vital capacity
The total amount of air that can enter or exit the lungs
200
What is bronchitis
Can be acute (bacterial) or chronic (irritants), inflammation of the bronchi
300
What is the diaphragm
The dome-like muscle that regulates pressure, and separates the thoracic cavity from the abdomen
300
What is internal respiration
The gas exchange between capillaries (blood) and body tissue
300
What is hemoglobin
99% of the blood oxygen is carried by this protein
300
What is residual volume
The amount of air remaining in the airways and lungs to prevent collapse
300
What are carcinogens
Cancer causing chemicals or toxins
400
What is the glottis
The opening to the trachea
400
What is cellular respiration
The process that produces the waste product to be exhaled
400
What are bicarbonate ions
70% of the carbon dioxide is dissolved as this
400
What is expiratory reserve volume
Excess air that can be forced out past the tidal volume
400
What is emphysema
The disorder where the walls of the alveoli break down and results in reduced surface area
500
What are the alveoli
The site of gas exchange between the air and blood
500
What is inspiration and expiration
The terms for inhaling and exhaling
500
What is blood pH
The primary regulator of breathing detects a decrease in this value
500
What is vital capacity - tidal volume - expiratory reserve volume
A way to measure the inspiratory reserve volume (formula) - used in lab
500
What is cystic fibrosis
A genetic chronic condition that results in the overproduction of mucus that cannot be coughed out, significantly reduces life expectancy
