respiration Flashcards
respiration is the process by which
gaseous exchange takes place between a living organism and the environment
respiration is also the breaking down of
food substances for the release of energy
respiratory system plays an important role in maintaining
homeostasis
how does the respiratory system maintain homeostasis
by giving oxygen and removing carbon dioxide, it maintains the constant internal environment for cellular metabolism
what are the 2 types of respiration
aerobic
anaerobic
aerobic respiration
takes place in presence of oxygen
ex. respiration in humans
C6H12O6 + 6O2 –> 6CO2 + 6H2O + 38 ATP (energy)
anaerobic respiration
takes place in the absence of oxygen
ex. certain bacteria, fungi, etc.
C6H12O6 —> 2C2H5OH + 2CO2 + energy
in our body ______ is taken in and ______ ______ is removed as a _____ _____
oxygen
carbon dioxide
waste product
when we respire anaerobically we produce
lactic acid instead of ethanol
lactic acid gives us cramp
C6H12O6 –> 2C3H6O3 (lactic acid)
the respiratory organs consists of
an air conducting zone
respiratory zone
air conducting zone (general definition)
which brings air into and out of the lungs
respiratory zone (general definition)
where gaseous exchange occurs across the alveoli where oxygen is transferred from inhalded air to blood and carbon dioxide is transferred from the blood to the air in the lungs
