Jump Start• Turn in your project
• On a piece of paper, answer the following:
– How many chambers does a bird heart have?– In a bird, where is the food stored before it enters
the stomach?– Birds are considered ectothermic or endothermic?
MammalsClass Mammalia
Characteristics
• Integumentary– hair, 2 pair of appendages, 5 digits, larynx
with vocal cords, have a highly developed immune system to recognize and destroy pathogens
Characteristics
• Skeletal/Muscular– 7 cervical vertebrae; Variety of limb
adaptions Can run, walk, climb, burrow, fly, swim, leap
Characteristics• Circulatory
– 4 chambered heart, 2 separate loops, complete separation of oxygen rich/oxygen poor blood
• Reproductive– Dioecious – different sexes, internal
fertilization, viviparous – live births, placenta, mammary glands
P2 = slate
• What are at least two distinguishing features of mammals?
Characteristics• Nervous
– Highly developed cerebrum/cerebellum, & senses to detect and respond to stimuli. Endocrine system to regulate body activities by hormones
• Respiratory– Diaphragm, lungs with alveoli instead of air
sacs, lungs are controlled by two sets of muscles for inhalation and exhalation
Characteristics• Digestive
– Complex teeth, herbivores (many have specialized digestive organs to break down plant matter), carnivores, omnivores
• Excretory– Highly developed kidneys extract urea and
help excrete or retain water as needed
Characteristics
• Body Temperature– Endothermic, may also have sweat glands
• Habitat– Land and water
P2 = Turn to your partner
• Describe how to distinguish between a herbivore and a carnivore by looking at an animals teeth.
Groups of Mammals
• Monotremes – egg laying, have cloaca (platypus)
• Marsupials – immature young develop in external pouch (kangaroo, koala)
• Placentals – embryo develop longer inside mother (human, dog, elephant)
