give vertebrates a strong support
strong, but more flexible than bones
series of similar bones that support the body and protect the spinal cord
covers and protects the brain
protect vital organs
such as fins, flippers, arms, legs, or wings
regulates its body temperature by internal means .
Includes: mammals and birds
animals that cannot control their body temperatures internally. Cold blooded animals- frogs and snakes
Transport substance such as oxygen( O2) and nutrients throughout. THe major parts are BLOOD and HEART.
Carries abundant oxygen away from the heart. Travels through arteries and is bright red in color.
(Red on a chart)
Travels through veins. Given most of it's oxygen to the body's cells and has taken on carbon dioxide from these cells. . Dark red in color.
(blue on chart)
spaces in a vertebra heart that are made of muscle.
two chambered heart
one receives blood and the other pumps blood to the body. Example: fish
one collect oxygenated blood from lungs; another collects deoxygenated blood from the rest of body. Both are emptied into third chamber where the two types of blood are mixed. Examples: most reptiles. including : toads, frogs, and salamanders.
two chambers on one side of heart pump only oxygenated blood and two chambers on the other side pump deoxygenated blood to the lungs(where it became oxygenated) then out to the rest of the body. Example: birds and mammals
functions in gas exchange. Supplies the body with fresh O2 and carries away CO2 waste.
take oxygen from the water and give off CO2 . Fish, lobster, clams, and some worms have gills.
microscopic blood vessels
Air chambers inside an animal's body where blood can obtain oxygen and give off carbon dioxide.
A thin layer of muscle that separates the chest chamber from the abdomen
1. Peripheral nervous system
2. Central nervous system
The nervous system has two main divisions. What are they?
central nervous system
Made up of the brain and spinal cord.
THe brain is protected by the skull and the spinal cord is protected by bones of the vertebral column
peripheral nervous system
Made up of NERVES that branch off the central nervous system.
nerves that branch from the brain . Carries impulses from the eyes, nasal sac& tympanic membranes to the brain
nerves that branch from the spinal cord
a major collection of sensory receptors and various supporting structures. example: eyes
Esophogus, stomach, small intestine(liver, Pancreas), large intestine.
List the parts of the Digestive system:
Short tube that takes food from the mouth to the stomach
muscles in the stomach walls squeeze the stomach in and out to mix the food with digestive enzymes.
the structure that digests and absorbs food.
greenish fluid called bile helps break down fats .(liver is attached to Small intestine)
smaller organ, makes and releases enzymes that break down sugars, starches, protein and fats.
(attached to small intestine)
where food that cannot be digested goes and where excess water is absorbed.
Animals that eat plants
Examples: Grazing animals
Animals that eat other animals
Examples: sharks, frogs, snakes, many birds
Eat both plants and animals.
Examples: bears and pigs
the study of living thing to discover solutions to human problems.
kidneys, urea, ureter, urinary bladder
What is in excretory System?
filter wastes from their blood
waste products formed as cells use proteins picked up by the blood
one large tube in each kidney where wastes flow through
where urine is collected and stored
Fish are ectothermic.
Fish must spend their lives moving, eating, breathing underwater. Fish are vertebraes. A fish propels itself by flexing its entire body. Has a closed circulatory system and two chambered heart.
List three things you know about fish.
Helps some fish float at a constant depth. It is an air filled organ.
Overlapping plates that protect the fish
A string of sensory structures that can detect vibrations and pressure
Female fish release millions of eggs which are then fertilized by the male.
1. Jawless fish
2. Cartilaginous fish
Fish are divided into three main groups. Name them.
Fish with no jaws . No scales or paired fins. Wormlike creatures with skeletons composed of cartilage. Two examples: lampreys and hagfish
These fish have endoskeletons made of cartilage. They have jaws, scales, and paired fins
Examples: sharks, skates, and rays
The largest group of fish. Examples: catfish, bass, flounder, goldfish, guppies, and trout
Ectothermic vertebrate that usually live in water when young but on land as adults. "Double Life"
Amphibians change from a gilled aquatic organism to an air-breathing organism through a process called__________________________.
***Amphibians are the only vertebrates that undergo this.
What am I?
Smooth moist skin. Usually live near the water. I eat insects, worms, slugs and snail. I have two sets of teeth: maxillary teeth and vomerine teeth.
What am I?
Rough, dry, bumpy skin. Adults may be far from the water. Amphibian
Forms a ridge around the rim of the upper jaw of a frog.
Located in two spots at the front of the roof of the mouth of the frog.
The tail is gradually dissolved and the materials are reused elsewhere.
Tadpoles have gills and tails, but during metamorphosis they develop lungs and ________________ their tails.
1. THey are amphibians that have tails in adulthood.
2. Many species secrete distasteful substances to deter predators.
3. THey are tailed AMPHIBIANS
LIst three important details about salamanders:
Some move back and forth from land to water. All breathe air. Do not experience metamorphosis.
What am I?
I have no legs, no ear opening. I do not hear. I am a carnivore, have double hinged jaw. I am found in every environment. I am a REPTILE.
WHat am I?
I have a broad rounded snout. I am a REPTILE.
What am I?
I have a narrow, pointed snout. Some of my teeth stick out of my jaw. I am a REPTILE.
________________ turtle lives in the ocean.
I am a reptile.
_______________________ live their entire lives on land. hint: type of turtle. I am a reptile
______________ live in or near fresh or brackish water.
hint: type of turtle. I am a reptile.
1. They are made of cells.
2. Require energy.
3. capable of growth.
Three vertebrae characteristics
Heavy fur, thick layer of feathers, and small ears keep animals from falling below proper range.
