True or false: Ureters in the excretory system filter blood and produce urine.
False: kidneys
How does the circulatory system work with the excretory system?
To carry wastes away from the cells.
What are the main functions of the circulatory system?
1. Transports oxygen to cells
2. Removes carbon dioxide from cells
What is the main functions of the respiratory system?
1. The exchange of oxygen and carbon dioxide between the blood and the cells of the body

Give an example of where you could find each one.
1. Skeletal - arm or leg
2. Smooth - respiratory or digestive tract
3. Cardiac - heart
What are the 2 main functions of the excretory system?

2. Remove toxins from the body
Compare and contrast movable and immovable joints.
Movable - allow for movement (elbow/ knee)
Immovable - bones are connected but do not move (skull)
