The skeletal and muscular systems of human are shown above. List three systems, other than skeletal and muscular systems, the organism had when alive that help
it to survive. Describe how each of these three systems contributed to maintaining
homeostasis.

The other systems I am aware of are...

Immune System: fights off disease-causing germs and other harmful substances

Respiratory System: works to move oxygen throughout the body and clean out waste gases like carbon dioxide

Cardiovascular System: delivers oxygen, nutrients, hormones, and other important substances to cells and organs in the body using blood

Nervous System: transmit signals between different parts of the body so we can move our muscles

Digestive System: breaks down food into small molecules, which are then absorbed into the body

Excretory System: removes waste from the human body
