Vertebrata
All vertebrates belong to which Phylum?
Cnidarians (jellyfish, coral, sea anemone, hydra)
A phylum that captures its prey using hematocyst
Have: Digestive Nervous and Excretory System
Don’t Have: Circulatory and Respiratory System
Which of the following system are present in the phylum Platyhelminthes? (flat worms, parasites)
Have: Digestive and a nervous system
Don’t Have: Circulatory, Respiratory, Excretory System.
Which of the following system are present in the phylum Cniderian? (Jellyfish, coral, Sea anemone, hydra)
Have: EVERYTHING nervous, circulatory, respiratory, excretory, complete digestive system.
Which of the following system are present in the Phylum Mollusca? (clams, snails, slugs, octipi, squid, oysters)
Cnidarians
Animals through this Phylum distribute nutrients throughout their body only by diffusion.
Annelid (segmented worms) earthworms, leeches, tube worms etc.
Animals in this phylum have the system that removes cellular waste from the body
arthropoda (insects, crayfish,horseshoe, crabs, spiders, centipedes.
Animals in this phylum have a nervous system that is controlled by the brain
cnidaria (jellyfish, coral, sea anemone, hydra)
Animals in this phylum take in food and remove it from the same opening
All phylum
Animals in this Phylum acquires oxygen from the environment
Porifera
Sponges
Porifera
Cnidarians (Jellyfish, Coral, Sea anemone, Hydra)
~Capture their prey using stinging cells called nematocysts. Each nematocyst has a harpoon-like that shoots into victim
~Cnidarians have 2 layers of cells separated by a thin- jelly like substance.
~Incomplete Digestive System they distribute nutrients by diffusion.
~NO CIRCULATORY system or RESPIRATORY System
~Have a simple nervous system called a neural net. No central control. They also have muscles so they can move.

HAVE: Digestive and Nervous
DON’T HAVE: Circulatory Respiratory, Excretory

Cnidarians (Jellyfish, Coral, Sea anemone, Hydra)
Platyhelminthes (Flat Worms)
~3 layers of cells.
~Incomplete digestive system that runs through body. Nutrients are distributed by diffusion no need for a circulatory system.
~Because they have 3 layers of cells flatworms do not remove cellular waste efficiently. They have primitive excretory system that reabsorbs water and concentrates cellular waste before expelled.
~Have a nervous system that is centrally controlled by a ganglion. Can learn simple tasks.
HAVE: Digestive, Nervous, Excretory, System.
Don’t Have: Circulatory or Respiratory
Platyhelminthes (Flat Worms)
Aschelminthes (Roundworms)
~3 layers of cells.
~Complete Digestive System.
~Nutrients are distributed by diffusion so no need to have a circulatory system.
~Oxygen can be obseved from the skin and cellular waste can be removed by diffusion.
~Nervous system controlled by the ganglia.
Have: Nervous, Complete digestive,
Don’t Have: circulatory , respiratory, excretory system
Aschelminthes (Roundworms)
Annelida (earthworms, leeches, tube worms)
~3 layers of cells
~complete digestive system
~Nutrients and Oxygen are transported through the body using a circulatory system
~Have a nervous system that is controlled by a set of ganglia.
~Use excretory system to remove cellular waste.
~Obtain oxygen through their skin and don’t need a respiratory system uses gills to obtain oxygen.
Annelida have everything!
Annelida (earthworms, leeches, tube worms)
Mollusca (clams, snails, slugs, octopi, squid)
~Complete digestive system
~Nutrients and Oxygen is carried out by the Circulatory System
~Cellular waste is concentrated in the excretory system before being expelled
~Respiratory system the consists of gills.
THEY HAVE EVERYTHING
Mollusca (clams, snails, slugs, octopi, squid)
Arthropoda (insects, crayfish, horseshoe, spiders, centipedes millipedes)
largest and most successful animal phyla. All have a hard exoskeleton made of chitih
~complete digestive system
~nutrients are sent throughout the body using the circulatory system
~Cellular waste is concentrated by the excretory system
~highly developed nervous system that is controlled by the brain. The brain is often aided by ganglia that helps coordinate movement.
Arthropoda (insects, crayfish, horseshoe, spiders, centipedes millipedes)
Osteichthyes - bony fish
~ the digestive and excretory system of vertebrates do not vary much from fish mammals
~ the respiratory system my fish use gills all rest of vertebrates use lungs
~ the circulatory and nervous system very a lot from fish to mammals
~ methods of a production very greatly among the vertebrates

~ circulatory system has a two chambered heart oxygenated and deoxygenated blood mix and it’s not efficient

Cerebrum-small and smooth
Cerebellum-small and smooth

Osteichthyes – bony fish
Amphibians (frogs toads, salamanders)
~Live on land but must return to water to reproduce fertilization is external.
~ circulatory system has to three chamber heart oxygenated and deoxygenated blood mix but not as much as fish therefore more efficient

Cerebrum- smooth medium sized
Cerebellum- smooth and medium sized

Amphibians (frogs toads, salamanders)
Reptile (lizards, snakes, alligators, crocodiles, turtles)
~Live on land and fertilization is internal.
~has a three chambered heart but better divided than I’m amphibian less mixed oxygenated and deoxygenated blood

Cerebrum-large and smooth
Cerebellum -large and wrinkled

Reptile (lizards, snakes, alligators, crocodiles, turtles)
Avians (birds)
~ Live on land internal fertilization lay eggs coded by Shell to prevent them from drying out
~ circulatory system has a 14 for Craig no mixing of oxygenated and deoxygenated blood
Cerebrum-large and slightly wrinkled
Cerebellum- large and very wrinkled
Avians (birds)
~All have hair females produce milk to feed their young
~most live on land fertilization is internal all but the platypus give birth to them to live young
~Circulatory system has a four chamber heart
Cerebrum and Cerebellum is very large and wrinkled
Mammals (dolphins, squid)
Blood does not stay within blood vessels. Blood leaves blood vessels and circulates throughout the body. Blood is collected and pumped back into blood vessels
Open circulatory system
Blood stains entirely within blood vessels. Blood vessels grow increasingly smaller as the blood flows away from the heart. Eventually wind up in the smallest blood capillaries where most of the gas and nutrients exchange take place.
Closed circulatory system
Invertebrates
Porifera-sponges
hideria-coral, jelly fish, hydra
platyhelminthes- flat worms
aschelminthes-round worm
annelida-earthworms
Mollusca-clams,snails,squid, oysters
Arthropoda-crabs
Invertebrates
Chordichtyes- sharks
Osteichthyes- fish
Amphibia- salamander
Reptilia- lizard
Ave-birds
Mammals- squirrels
Vertebrates
