Animal Systems Study Guide
Name:_________________________
Test Date:_______________________
Dear Parent or Guardian,
5th graders just finished a unit on animal systems. On the date above, we will be
having a final test over the unit. Please help your child to review by having
him/her study the following pages.
Objective: Identify the function of each body system
1. circulatory system – the organ system that moves blood through the
body
a. blood – red fluid circulating in body: the red fluid that is pumped
from the heart and circulates around the bodies of humans and
other vertebrates
b. blood vessel – an artery, vein, or capillary through which blood
flows
c. heart – a hollow muscular organ that pumps blood around the
body
2. digestive system – the organ system that breaks down food
a. stomach – breaks the food down into smaller parts
b. small intestine – absorbs nutrients from food
3. excretory system – the organ system that removes wastes from the
body
a. liver – a glandular vascular organ in vertebrates that secretes bile,
stores and filters blood, and takes part in many metabolic
functions such as the conversion of sugars into glycogen
b. kidney – waste-removing vertebrate organ; either of a pair of
organs in the abdomen of vertebrates that filter waste liquid
c. bladder – bodily sac for liquid or gas
d. skin – natural layer covering body; the external protective
membrane or covering of an animal's body, consisting of the
dermis and epidermis and often covered in hair, fur, scales, or
feathers
4. muscular system – the organ system made up of muscles that help the
body move
a. muscles – tissue that allows for body movement
5. nervous system – the set of organs that uses information from the five
senses to control all body systems
a. brain –the controlling center of the nervous system, connected to
the spinal cord
b. nerve – a bundle of fibers that sends messages between the brain
or spinal cord to all other parts of the body
6. reproductive system – the set of organs that make it possible for
organisms to start the life cycle over again
7. respiratory system – the organ system that brings oxygen to body cells
and removes the waste gas carbon dioxide
a. lungs – takes in oxygen from the air and releases carbon dioxide
8. skeletal system – the organ system made up of bones that support the
body
a. bones – section of skeleton: one of the hard parts forming the
skeleton in vertebrate animals
Objective: Explain how systems work together to perform activites
Skeletal System and Muscular Systems: The skeletal and muscular work together
to give movement to the human body. Muscles attach to the bones and contract
or relax to make the bones move.
Circulatory and Respiratory Systems: The circulatory and respiratory systems
work together to bring oxygen into the body and to carry it to every cell.
Circulatory and Excretory System: The circulatory and excretory systems work
together to remove wastes from the body. Circulatory system removes wastes
from the cells. The excretory system carries the waste out of the body.
Digestive System and Excretory System: The digestive and excretory system work
together to take in food and remove it from the body after digestion takes place.
Nervous System and all other systems: The nervous system controls every other
system in the body. It sends signals to nerves controlling the running of each
system.
