Respiratory system, circulatory system, what stuck, digestive system, and how do they work together?

They all regulate and support your body’s functions. They all work together by stabilizing each detail and movement of your body and keeps it functioning.

The respiratory system brings oxygen into the lungs when you breathe. The digestive system breaks food down into nutrients such as glucose. Now the circulatory system enters the picture. It transports glucose and other nutrients from the digestive system to the cells. Hope this helps!
