The reproductive system.
The reproductive system is responsible for allowing organisms to continue as a species by producing offspring through sexual reproduction. This system involves the production of gametes (sperm and eggs) and the internal and external structures involved in mating and fertilization.
Organisms with a closed circulatory system are likely to have a circulating body fluid distinct from the fluid that directly surrounds the body's cells. In a closed circulatory system, the blood is contained within vessels and separate from the interstitial fluid that surrounds the cells. This system allows for more efficient nutrient and waste exchange.
skeletal allows movement. No system allows movement of organs LOL
muscular system
Muscles.
do all living organisms need your body system to survive

aids is a disease caused by many organisms
When a snake's head is removed, its body can still move because snakes have a unique nervous system that allows them to function independently of their brain. The nerve cells in a snake's body can continue to send signals and control movement even without input from the brain.

The nervous system allows the body to send and receive messages and respond to the world around it.
The skeletal system supports the body by providing structure and protection to internal organs. It also works together with the muscular system to allow movement.
