the organ system that brings oxygen to body cells and removes waste gas
Term
excretory system
Definition
the organ system that removes liquid wastes
Term
digestive system
Definition
the organ system that breaks down food for fuel or energy
Term
skeletal system
Definition
the organ system made up of bones
Term
muscular system
Definition
the organ system made up of muscles that move bones
Term

Definition
the organ system that controls all other body systems
Term
Name the seven body systems.
Definition
1. circulatory system
2. respiratory system
3. excretory system
4. digestive system
5. skeletal system
6. muscular system
7. nervous system
Term
Which system controls all of the other systems?
Definition
the nervous system
Term
Name the parts of the circulatory system.
Definition
1. heart
2. blood
3. blood vessels
Term
What are the jobs of the circulatory system?
Definition
1. bring food,water, and oxygen to cells
2. remove waste
Term
Which animals have circulatory systems?
Definition
All animals but sponges and cnidarians
Term
What are the two types of circulatory systems?
Definition
1. open
2. closed
Term
Name the parts of the respiratory system.
Definition
1. lungs, gills, or skin
Term
What are the jobs of the respiratory system?
Definition
1. brings oxygen into body
2. removes waste gas (carbon dioxide)out of body
Term
Describe the five steps of the human digestive system.
Definition
1. Food is broken down by teeth and saliva.
2. It passes to the stomach through the esophagus.
3. Acids break down the food. Stomach muscles mix it.
4. Food passes into the small intestine. Chemicals from the liver and other glands mix with the food. When it is digested, nutrients are absorbed into the blood through the small intestine's walls.
5. Solid wastes are passed to the large intestine.
Term
What type of tissue is blood?

Definition
urine
Term
Are bones living tissue?
Definition
Yes
Term
Vertebrates use _______ and ________ together to move.
Definition
Vertebrates use "bones" and "muscles" together to move

Definition
You can "take good care of them."
Term
Do insects and other invertebrates have open or closed circulatory systems?
Definition
open (except some complex invertebrates like the earthworm)
Term
Do vertebrates have an open or closed circulatory system?
Definition
