Health and Fitness Question 5

The circulatory, respiratory, digestive, and excretory systems are very important to the body, they are considered transport systems because they all help the body remove wastes some how. The circulatory system delivers important materials to the body. these materials pass through the body by the blood. The respiratory system's job is to take in oxogen (which body cells need) and get rid of carbon dioxide (A waste gas). When you breathe in, air enters through your nose, the air then passes through the trachea(Windpipe). The digestive system really helps you remove wastes it digests the food you eat and removes it as waste.
