Respiratory System Flashcards
what are the three different types of respiratory systems
direct diffusion, skin/gills, and tracheal
what is the tracheal system key component
small tubes to carry oxygen
how does the skin/gill system work
oxygen diffuses across the gill surfaces from high to low concentration
how does direct diffusion work
direct diffusion across outer membrane
what system do humans use
mammalian system
branching system of what is used is mammals
bronchi
terminal bronchiole ends in what
alveoli
what are the two protective mechanisms to remove particles
cilia and mucus
in tissues does gas flow with or without the gradient
with the gradient high to low
in the lungs does gas flow with or without the gradient
with the gradient high to low
what enzyme within red blood cells catalyzes the reaction CO2 + H2O to make H2CO3
carbonic anhydrase
on the tissue side the H+ binds to what
hemoglobin
what is exported out of the red blood cell into the plasma in exchange for Cl-
HCO3 -
on the lung side what diffuses out of the red blood cells into the alveolus
CO2
