Mammal review

Order of mammals which includes humans. Primates In carnivores these teeth are larger Incisors canines premolars molars canines

Process used by bats in which high frequency sound waves are bounced off objects to help in navigation. echolocation Flat sheet-like muscle located beneath the ribcage which helps move air into and out of the lungs. diaphragm

This portion of the brain which controls This structure which receives digestive & urinary waste as well as sperm/eggs is MISSING in all mammals (except monotremes) cloaca This portion of the brain which controls higher level thinking and learning is larger in mammals cerebrum

Most mammals belong to this group Name 3 characteristics of mammals Endothermic Hair 4 chambered heart Feed milk to young Single lower jawbone Specialized teeth Most mammals belong to this group Monotremes Marsupials Placental mammals Placental

Reproductive structure that stores sperm in males. Seminal vesicles Aquatic, carnivorous, flipper limbed mammals including seals, walruses, and sea lions are called pinnipeds

These structures give mammals their name and Mammals provide nourishment to their developing embryos growing inside the mother through this structure placenta These structures give mammals their name and provide milk to nurse their young. Mammary glands

How are the exit openings in the lower body of a rat different from that of a frog, turtle, or bird? Amphibians, reptiles, and birds have only ONE opening (vent). Digestive, excretory, & reproductive all empty into cloaca and exit through the same opening. Mammals have separate openings. Females have 3 (digestive, excretory, & reproductive) Males have 2 (excretory and reproductive share one opening)

Thin plates made of keratin which hang from the roof of the mouth in certain whales and strain food from the water. baleen First chamber in the stomach of a cud-chewing mammal like a cow which contains bacteria to digest plants. rumen

Mammals with hooves such as deer, elk, zebras, and horses. Ungulates Bean shaped excretory organs which remove urea from the blood kidneys

Warm-blooded = ____________________ Large sac that branches from the intestine in non-cud chewers such as rabbits, horses, rodents, and elephants which contains microorganisms to digest plants. cecum Warm-blooded = ____________________ endothermic

the group of mammals called ______________ This animal belongs to the group of mammals called ______________ marsupials Excretory organ that is missing in birds, but seen in mammals. bladder

Male reproductive structure where Sperm mature and grow tails. epididymis Female reproductive structure where the embryo grows and is nourished by a placenta uterus

The only North American marsupial is the ___________________ oppossum Number of chambers in a mammalian heart. four

Located near the liver this structure stores bile Gall bladder The organism (rat) pictured belongs to this group of mammals Monotreme marsupial placental It is placental

Name a characteristic of primates Whales, dolphins, and porpoises belong to this order of mammals. cetaceans Name a characteristic of primates Larger brain, grasping hands, forward facing eyes

Cud-chewers have a _______________ Reproductive organ that makes sperm. testes rumen Cud-chewers have a _______________ Cecum rumen cloaca

Bats use this sense when they navigate with echolocation. hearing One way you can tell a mammal fossil from a reptile fossil is to look at the ____________ Jawbone (mammals have a single bone in lower jaw) Teeth (mammals have specialized teeth based on diet)

Mammals are ____________________ Endothermic Ectothermic Endothermic Structure near the liver which produces digestive enzymes used in the small intestine to break down food pancreas

Air sacs in the lungs called _________________ increase surface area and absorb more oxygen. alveoli Mammals can be divided into 3 groups based on their reproductive strategies. Name the 3 kinds of mammals. Egg layers (monotremes) Carry babies in pouch (marsupials) Nourish baby with placenta (placental)

placental Humans are ____________________ mammals. Monotreme Marsupial Placental Name one of the digestive parts seen in plant eating mammals that contains microorganisms for digesting food. Cecum OR Rumen

Digestive organ that absorbs nutrients from food Small intestine The only flying mammals are __________ bats

Organ in males that transfers sperm to the female reproductive tract Animals with a cloaca have a vent; organisms without a cloaca have an __________ anus Organ in males that transfers sperm to the female reproductive tract penis

Integumentary adaptation in mammals to keep warm Hair or fur What’s special about a rat’s teeth that’s different from ours? Grow continuously

Name the 3 parts of the small intestine in order starting near the stomach. Duodenum, jejunum, ileum appendix In humans the _________________ is what is left of our cecum (vestigial).

The ___________________ absorbs water And concentrates waste. Monotremes ________________ are the only mammals with a cloaca Large intestine The ___________________ absorbs water And concentrates waste.

Like birds and reptiles, mammals have ______________ fertilization. The _______________ divides the lower portion in a rats’s heart into two ventricles. septum Like birds and reptiles, mammals have ______________ fertilization. Internal external internal

Reproductive organ that makes eggs You would expect a mammal that is a plant eater to have lots of teeth like these. incisors canines premolars molars Molars – flat for grinding Reproductive organ that makes eggs ovary

Type of coelom found in mammals True coelom (coelomates) deuterostomes Mammals are ________________ protostomes deuterostomes

Mammals have a _____________ to store urine. Non-cud chewers like horses, rabbits, rodents, elephants have a __________________ Cecum rumen cloaca cecum Mammals have a _____________ to store urine. bladder

panceas cerebellum cerebrum epididymis Match the MAMMAL body part with its function Makes digestive enzymes for the small intestine _____________ Controls muscle coordination _____________ Controls higher thinking and learning _________________ Coiled tubules where sperm mature and grow tails _______________ panceas cerebellum cerebrum epididymis

This part of the brain controls coordination cerebellum This part of the brain controls the Internal organs. Medulla oblongata

bladder uterus Small intestine kidneys Mammary glands Match the mammal body part with its function Stores urine ______________ Muscular organ where embryo develops _________________ Completes digestion & absorbs nutrients ________________ Removes urea from blood _____________ Produce milk ______________ bladder uterus Small intestine kidneys Mammary glands

Which of the diagrams shows the kind of circulatory system found in mammals? 4 chambers 2 loops

Tell one way Mammals are like birds Both: are deuterostomes are coelomates in same Kingdom (Animalia), phylum (chordates) subphylum (vertebrates) are endothermic have 4 chamber heart have 2 loop circulatory system internal fertilization separate sexes ….. There are lots more

RATS belong to the Kingdom __________________ Phylum _________________ Subphylum ________________ Class _____________ Order ______________ Animalia chordata Vertebrata Mammalia Rodentia

Egg-laying mammals like the platypus are in the group of mammals called _______________ monotremes T or F This animal has a cloaca. True Egg laying mammals do.

Match the MAMMAL body part with its function Windpipe ______________ Pouch where microorganisms help digest plant material __________ Stores bile _____________ 1st chamber in the stomach of a cud-chewer ________________ Collects & processes blood removing worn out cells _____________ trachea cecum Gall bladder rumen spleen
