74
Q
  1. How are Fish, mammals, Birds and Tetra different?
A

Vertebrate hearts can be categorized by the number of chambers they have: Two chambers: one atrium and one ventricle (fish) Three chambers: two atria and one ventricle (amphibian and reptile) Four chambers: two atria and two ventricles (bird and mammal)

Respiration =
Birds are efficient, Highly efficient lungs - flow-through parabronchi, airsacs
Air flows unidirectionally over gas exchange surface Channels = parabronchi
Mammals have lungs
Fish have gills
Amphibians have lungs but breath through skin
