The Effects of Nutrition on the Excretory System

The excretory system is the body's primary means of eliminating waste products. There is a direct correlation between nutrition and the waste that is produced, which then has to be eliminated.

  1. Connections

    • Every system in a body is connected to the entire organism -- circulatory, respiratory, digestive, reproductive, excretory. What affects one can also affect the others.

    The Digestive System and the Excretory System

    • The digestive system is how an organism converts food into energy, and the excretory system is how an organism rids itself of waste products produced by the digestive system.

    Digestion

    • Digestion happens in the small intestine. Any food that doesn't get absorbed moves into the colon. The less nutritious a food, the more it needs to be expelled from the body.

    Kidneys and Waste

    • Your kidneys filter blood, removing waters and salts that might be present. An average person's kidneys go through about 200 quarts of blood a day and remove about 2 quarts of waste material and water.

    Nutrition and Excretion

    • The more nutritious the diet, the less waste is excreted. Foods that are high in protein and low in starches will produce less waste than foods that are composed of fillers and other non-digestible materials.
