Question

how is the circulatory system is connected to three other bodily systems?

Answer 1

They all use the bloodstream as a highway to transport their products.
-Endocrine sytem secretes hormones into the circulatory system.
-Respiratory system provides the circulatory system with oxygen and takes out carbon dioxide.
-Digestive system breaks down nutrients and they're absorbed into the circulatory sytem and transported to all the parts of the body.

You also have the skeletal system which produces blood cells for the circulatory system

Hope this helps :)

Answer 5

but what do you not understand from my explanation?

-Endocrine sytem secretes hormones into the circulatory system.
-Respiratory system provides the circulatory system with oxygen and takes out carbon dioxide.
-Digestive system breaks down nutrients and they're absorbed into the circulatory sytem and transported to all the parts of the body.
-Skeletal system produces blood cells for the circulatory system.
-Muscular system, the circulatory system provides the muscles with oxygen and nutrients by transporting these materials.
-Immune system uses the circulatory sytem to fight invaders (white blood cells and antibodies in blood)
-Excretory system uses blood to get rid of waste products.

You only have to pick 3 of these and you have your answer.
