| A | B |
|---|
| Bird | Endothermic vertebrate with feathers, four-chambered heart, and lays eggs |
| Contour Feathers | Large feather that helps give streamline shape to bird's body; used in balancing/steering; contains barbs |
| Canines | Mammal's sharply pointed teeth used to stab and tear into food |
| Crop | Bird's internal storage tank for food |
| Down Feathers | Short fluffy feathers used to create and trap heat |
| Diaphragm | Large dome-shaped muscle that assists in a mammal's breathing |
| Gizzard | Muscular part of bird's stomach that squeezes and grinds partially digested food |
| Gestation Period | Length of time between fertilization and birth of a mammal |
| Insulator | Material that does not conduct heat well and helps keep heat from escaping |
| Incisors | Flat-edged teeth in mammals used to bite off and cut parts of food |
| Mammal | Endothermic vertebrate with a four-chambered heart, skin covered with fur or hair, and feeds young with milk from mom's body; classified according to how the young develops |
| Mammary Glands | Organ that produces the milk mammals feed to their young |
| Marsupial | Mammal whose young are born live at early stage of development; development continues in pouch on mom's body; Ex: kangaroo, opossum, koala |
| Molars/Premolars | Mammal's teeth that grind and shred food |
| Placenta | Membrane found in some mammals that provides the link for materials to pass between mother and offspring |
| Placental mammals | Mammals that fully develop inside mother's body; ex: mouse, elephant, bat, horse |
| Monotreme | Mammal that lays eggs; Ex: spiny anteaters, duck-billed platypuses |
| Placental Grouping | According to movement and eating method; Ex: Insect-eating, Flying, Primates, Leaping, Rodent, Trunked, Toothless, Hoofed, Carnivore, Marine |
| Insect-eating | Star-nosed moles |
| Flying | Bat |
| Primates | Monkey,Apes, Gorillas |
| Leaping | Rabbit, Hare |
| Rodent | Rats, Beavers, Squirrels, Mice |
| Trunked | Elephant |
| Toothless | Sloth, Armadillos |
| Hoofed | Cows, Deer, Pigs, Horses, Zebra |
| Carnivore | Otter, Dogs, Cat, Bears |
| Marine | Whales, Manatees, Dolphins |
| Bird Characteristics | Vertebrate, Warmblooded, Most fly, Feathers, Lay eggs (rigid shells), Scales on feet & legs, Internal fertilization |
| Mammal Characteristics | Warm-blooded, Vertebrate, Skin covered with fur or hair, Feed offspring milk from mammary glands, mostly live births, 4-chambered heart, lungs, teeth; Clasified on how young develop |
| Mammal types | Monotremes (Egg-laying), Marsupial (pouched), Placental (complete internal development w/placenta) |
| Types of teeth | Incisors - bite/cut; Canines - stab/tear; Premolars and Molars - grind/shred |
| Endothermic | warmblooded |
| Ectothermic | cold-blooded |
| 2-Loop Circulatory System | More efficient delivery of oxygen to body cells/tissues; heart - lungs - heart, heart - body cells/tissue - heart |
| Bird types | Perching, Water, Bird of Prey, Flightless |
| Beak types | Strainer (duck), Probe (humming bird), Chisel (woodpecker), Shredder (Hawk) |
| Feet types (Birds) | Grasping (Hawk), Climbing (Woodpecker), Swimming (Duck), Perching (Humming bird), Running (Ostrich) |
| Blood path of 4-chamber heart double loop circulatory system | Enters heart in right atrium, flows to right ventricle, flows to lungs (picks up oxygen/drops off waste), flows to left atrium, flows to left ventricle, flows to body cells/tissues (releases oxygen/picks up wastes), flows to heart |
