Appendix - The Body and How it Works

Digestive and Urinary Systems

The digestive and urinary systems convert food and drink into nutrients for the cells and collect and dispose of solid and fluid waste. The organs of these systems are classified as hollow or solid. The hollow, tubular organs carry digestive and urinary materials. The solid organs are tissue masses with a rich blood supply.

Injury to hollow organs may allow the contents to spill out into the abdominal or pelvic cavities, causing infection. Injury to the solid organs can result in severe internal bleeding.
