The boxes that appear outside the logo are known as “resize handles.” Use these to resize the object. If you hold down the shift key before using the resize handles, you will maintain the proportions of the object you wish to resize.Diagrams needed in this presentation: Diagrams needed in this presentation Fish circulatory system Frog system Mammalian system Alligator moving vs. mammal moving Video of herbivore chewing, carnivore eating Frog gulping air Bird’s air sacs: diagram in motion People standing in line at Disney world (Pre show issue) Diagram of alveoli Reptile sunning itself on a rock Fish in water under ice: 4 degrees Celsius Etc. Slide3: Alveoli Objectives: Objectives Describe a single-loop circulatory system Describe a Double-loop circulatory system Compare two techniques of body temperature control in vertebratesSupport and Movement: Support and Movement Reptiles: horizontal limbs Mammals: vertical limbsFeeding and Digestion: Feeding and Digestion Carnivores: shorter digestive tract Herbivores: longer digestive tract Why? Plant material takes longer to digest!Respiration: Respiration Gills: fish, larval amphibian Lungs: adult amphibian Air sacs: birds Lung: mammals Bronchi Alveoli What are some structures used for respiration in vertebrates?Most efficient in Birds: Most efficient in BirdsSlide9: People at DisneylandSlide10: birds - air sacsAir Sac: Air SacSlide12: frog gulping air?
