Respiratory System Flashcards
1
Q
Cellular Respiration
A
Glycolysis, Citric Acid Cycle, Electron
Transport Chain
– Respiratory Quotient (RQ) – ratio of CO2
produced to O2 Consumed
2
Q
External Respiration
A
Transport of O2 and CO2 between blood and
tissues
3
Q
The steps of External Respiration
A
The steps – Breathing – O2 and CO2 exchange between air and blood – O2 and CO2 transported in the blood – O2 and CO2 exchange between blood and tissues
4
Q
Partial pressure
A
the force exerted by a gas
Partial pressure gradients determine where
gasses will diffuse.
5
Q
Hemoglobin
A
Four Subunits • Porphyrin Ring – Iron • Allosteric Binding • Deoxyhemoglobin • Oxyhemoglobin
6
Q
Gasses in the Blood
A
Oxygen and Carbon Dioxide
7
Q
Expiration
A
Typically Passive
8
Q
Surfactant
A
Works to keep alveoli open
• Decreases surface tension of alveoli
9
Q
Measuring Lung Volumes
A
Spirometer
• Tidal Volume
• Vital Capacity
