Mammalian respiratory system:
Avian respiratory system:
DIFFERENCES:
1) Mammals:
Birds:
2) Birds:
The active phase of respiration in birds is exhalation, requiring contraction of their muscles of respiration. Relaxation of these muscles causes inhalation.
during exhalation, thus allowing oxygen-poor air from bronchi to escape via the trachea to the exterior. Oxygenated air therefore flows constantly (during the entire breathing cycle) in a single direction through the parabronchi.
Mammals:
3) Birds:
Mammals:
4) Birds:
Mammals:
Q) 2:
Mechanism of respiration in turtle through shell:
Different respiratory systems different from mammals:
Fish
Birds
Insects--------- Tracheal system
Amphibians----- Skin
Earth worms---- Skin
Small multicellular organisms (Flat worms)—Diffusion
