Respiration Flashcards
Vital capacity
The maximum amount of air exhaled after the largest possible inhalation
VC= IRV + ERV + TV
Residual volume
The amount of air that remains in the lungs after complete exhalation
Inspiratory reserve volume
Amount of air in hailed vigourously after the normal inhalation
Exploratory reserve volume
Amount of air exhaled vigourously after a normal exhalation
Tidal volume
The amount of air in hailed and exhaled at rest
Spirometer
A machine that measures the amount of inhaled and exhaled air
Dead space
Amount of air that does not answer the lungs but remains in the trachea mouth or nose in between breaths
Explain what happens during inspiration and expiration
During inspiration, your diaphragm contracts and moves down pulling the lungs with it. The intercostal muscles move up and out the interior volume of the lungs will increase
The pressure in the lungs will decrease
This process is active
During expiration,
The diaphragm relaxes and moves up returning the lungs to a smaller size
The intercostal muscles relax and move The ribs in and down
The interior volume of the lungs decrease
Air will leave and it is forced out through the mouth or nose
This process is passive
Cellular respiration
Happens in the mitochondria of the cells and produces energy
Gas exchange : O2 is produced, CO2 is produced
C6H12O6 + 6O2 -> 6CO2 + 6 H2O + energy
Internal respiration
Between the blood and the cells
Oxygen goes from the blood to the cells while carbon dioxide goes from the cells to the blood
External respiration
Between the lungs in the blood oxygen will go from the air into the blood vessels while carbon dioxide goes from the blood vessels into the air
What is the function of cilia and mucus
Cillia filters the air while mucus moistens the air
