BIOL 1107 Chapter Notes - Chapter 46: Endodermic Evagination, Cellular Respiration, Invagination
Document Summary
Absorbed o 2 is used as final electron acceptor for cellular respiration, co 2 released is a product. Respiratory medium : environmental source of o 2 and sink for released co 2. Respiratory surface : formed by epithelial cells, provides interface between body and respiratory medium of insect to tissues throughout its body. Exchange of gas occurs by simple diffusion, rate becomes higher with increasing temp. Tracheal system : branching network of tubes that carries air from small opening in exoskeleton. Gills : respiratory organ formed as evagination of body that extends outward into respiratory. Lungs : one of a pair of invaginated respiratory surfaces, buried in body interior where they are medium less susceptible to drying out breathing. Ventilation : flow of respiratory medium (air or water) over external side of respiratory surface, Animals remove o 2 from respiratory medium and replace it with co 2 during respiration.
