Bio Q3 LG 1.3 Flashcards
it is the breakdown of sugar to form energy
cellular respiration
formula for cellular respiration
C6H12O6 + 6O2 = CO2 + H2O + energy
it is the constant demand of supply of oxygen to the body and the constant removal of CO2 from the body
Gas exchange
This happens between the environment and the respiratory organs
External Respiration
This happens between the capillary blood and the tissues
Internal Respiration
Formula for fick’s law
(Surface area * concentration of diffusion) / thickness
these are special surfaces that aid in gas exchange that are used to supply for the needed oxygen.
gas exchange surfaces
These are the properties of gas exchange surfaces
- moist
- thin membrane
- large surface area
5 exchange mechanisms for gas exchange in animals
- simple diffusion
- cutaneous respiration/integumentary exchange
- gills
- tracheal system
- lungs
simple diffusion
- for animals near oxygen-containing water
- for sponges, flatworms
- exchange between environment and cell surface
cutaneous respiration
- large animals in moist areas
- countercurrent exchange
gills
filamentous structures for organisms in water
countercurrent exchange
tracheal system
through branching tubes called trachae/ tracheal tubes
gasses move by diffusion
lungs
air-breathing vertebrates
