what does the image above show?

• the structure of the lungs

• the digestive system

• the skeletal system

what is the function of what is shown here?

• circulates blood around the body transporting essential nutrients and gases to all tisues.

• filters and cleans the blood removing waste products in the form of urine.

• takes in oxygen and exhales carbon dioxide. allows the process of gaseous exchange.

• holds the entire body in place and allows movement by contracting and relaxing.
