Function of the Digestive System. The primary function of the digestive system is to break down the food we eat into smaller parts so the body can use them to build and nourish cells and provide energy. The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
How the Urinary Tract Works. The purpose of the lower urinary system is to accumulate, store and eventually release urine from the body. Urine is water and liquid waste that's been filtered out of the bloodstream by the kidneys. From here, it's sent to the bladder and temporarily stored. The bladder is an elastic container located in the pelvis.
