biology chapter 32

make them available them to breath gills
backbone Vertebral column
made of either cartilage or bone with a Vertebral column surrounding spinal cord internal skeleton
Brain fully encased by skull/cranium
the blood is pumped from the heart to the gills where it is oxygenated to the rest of the body them back to the heart single loop circulation
unable to synthesis aromatic amino acids therefore they must consume these important protein building amino acids in there diet Nutritional requirements
breading season in the spring Reproductive organs
which is a fluid containing the sperm of strings of eggs while in and out of weeds and twigs in the water milt
recessive sensory information from the eyes they are large because of the important of the vision Optic lobes
receive information concerning smell from the chemical sensing cells Olfactory lobes
processes mainly sensory information Cerebrum
muscle activity Cerebellum
this controls function of many internal organs Medulla oblongata
thrusts from side to side to purples forward Caudal fin
prevents the fish from rolling as it swims Dorsal fin
it keeps the fish from slipping sideways Ventral anal fin
these assist in going up or down turning left and right and then stopping quickly Paired pectoral and pelvic fins
they are thin bony disks that grow from cavities in the skin they grow throughout there life forming growth rings which can give the age scales
able to structure and absorb its own gases the cells that make up the swim Blatter generate carbon dioxide by carrying out cellular respiration swim bladder
specialized sensory system that extends to each side of the fishes body lateral line system
gill cover and hard plat that covers the gills on each side of the head Operculum
gradually lost their legs due to adapting to a burrowing existence caecilians
______ amphibians have gills larval
_______ gills disappear and lungs have developed, not much surface area and the internal surfaces of tApodahe amphibian are poorly developed, Adulthood
respiring directly through the skin, skin is moist and provides extensive surface area Cutaneous respiration
after the blood is pumped through the lungs two large veins, the pulmonary veins, return oxygenated blood to the heart for re pumping, this allows for oxygenated blood to be pumped to tissues at a much higher pressure Pulmonary veins
atrium separated, but their is still a mixture of oxygenated and deoxygenated blood delivered to the tissues Partially divided heart
What are the 3 orders of amphibians Anura Urodela Apoda
Frogs and toads Anura
Salamanders and newts Urodela
wormlike, nearly blind Apoda
wormlike, nearly blind Caecilians
deserts to mountains, and ponds to puddles Anera habitat
eat a wide variety of insects Anera carnivore
external fertilization, larval form: tadpoles- they are herbivores, eating algae; they go through metamorphosis and become an adult frog becoming carnivores Anera reproduction
produces a lubricant to keep the skin moist so they can breath still anera skin
bulge from the head, therefore they can be almost fully submerged and have their eyes out, have a transparent membrane which keeps the eyes moist and protect the eye while underwater anera eye
sound causes the membrane to vibrate and the tiny bone transmits the vibrations to the middle ear, within the middle ear there are ciliated sensory cells that are able to detect sounds and help the frog maintain balance anera Tympanic membrane
Leopard frog reproduction External
more developed than the fish anera brain
it flicks out curls around its prey and flicks back in, the upper jaw is lined with small sharp teeth called, maxillas; have two larger teeth projected inward from the roof of the mouth to impale the prey called the vomerine; food is swallowed hole anera tonged
a cavity where the undigested food is pushed, the urine from the kidneys and bladder also pass through the cloaca, everything exits through the cloacal opening cloaca
only have 9 vertebrae and have no ribs, have a three way support structure that acts as a shock absorber for the long bones when. frog lands Skeletons
extends to the center of the pelvic girdle, the bones of the frogs hind legs insert directly into the sockets of the girdle sacral vertebrae
have an elongated body, with long tails, and smooth moist skin urodela body
have to be near water urodela habitat
external fertilization, they do not undergo metamorphosis, small versions of the adults with gills urodela reproduction
highly Specialized group of tropical burrowing amphibians, leg less and wormlike aopda body
varies from one foot to four feet aopda size
during breeding the male deposits sperm directly into the female, female can beat live young or lay eggs depending upon the species, aopda reproduction
