Question | Answer |
An animal with a backbone. They have _____________, skulls and endoskeletons. | vertebrate |
Made of a combination of bone and cartilage | endoskeleton |
gives vertebrates a strong support system | bone |
is strong but is more flexible than bone. It serves as a cushion in between joints and bones. | cartilage |
Is a series of similar bones that support the body and protect the spinal cord | vertebral column |
Covers and protects the brain | skull |
carries abundant oxygen (red blood in diagrams represent this) | oxygenated blood |
gives most of its oxygen to the body's cells and takes on carbon dioxide (the blue blood is this in diagrams) | de-oxygenated blood |
take oxygen from water and give off carbon dioxide | gills |
are chambers inside an animal's body where blood can obtain oxygen and give off carbon dioxide | lungs |
helps mammals and humans to breathe; is a thin layer of muscle that separates the chest chamber from the abdomen | diaphram |
Is made up of the brain and spinal cord | central nervous system |
is protected by the skull | brain |
is protected by bones of vertebral column | spinal cord |
is made up of the nerves, sensory receptors and sensory organs | peripheral nervous system |
is a major collection of sensory receptors and various supporting structures...normally a _______________ senses only 1 environmental factor (ex. the eye) | sensory organ |
food enters a vertebrate's body thru the mouth, then passes the short, tubular esophagus into this...once inside it mixes the food with digestive enzymes that are already in this | stomach |
After food is mixed, it moves here. It is the digestive organ in which most of the digestion & absorption of food occurs. | small intestine |
1 of the 2 organs attached to the small intestine is this, it produces a greenish fluid called bile which contains substances to help break down fats, the bile is stored in the gallbladder until needed. | liver |
a smaller organ that makes enzymes and releases them into the small intestine...these enzymes break down sugars, starches, proteins and fats | pancreas |
the part of the digestive tract that extend from the end of the small intestine to the anus; absorbs water and minerals | large intestine |
filters waste from the vertebrate's blood | kidneys |
in each kidney the wastes flow the capillaries into this which is one large tube | ureter |
urine is collected and stored in this before it passes out of the body | urinary bladder |
means that their body temp changes with their surroundings (ex. fish) | ectothermic |
What does a skull protect? | brain |

What organ do sharks not have that most bony fish have? | bones |
Which group of vertebrates is the only group to undergo metamorphosis? | frogs |
Why are most amphibians found near water? | They live in the water when they are young. Then they can live on land and water when they are adults. |
How are hibernation and estivation similar? How are they different? | Both slow life process; hibernation only occurs in winter |
What does a snake detect with its tongue? | food or danger |
What do snakes eat? | mice |
What system does the ureter belong to? | excretory |
What system does the spinal cord belong to? | nervous |
What system does the diaphragm belong to? | respiratory |
