How does waste get to the excretory system

The Excretory system is the system the body uses to get rid of all its wastes, and involves the lungs to remove carbon dioxide from the body, the large intestine where solid wastes pass through, and the kidneys which removes a lot of the liquid waste. The wastes then travel through the ureters to the urinary bladder.

The excretory system is the system the body uses to filter waste. Food travels through the esophagus, stomach, small and large intestine, pancreas, gallbladder and liver. Your body absorbs important minerals, fats, vitamins and carbs. The musces in your esophagus move the food along in about 2-3 seconds. The stomach's acids break down the food. The liquid mixture files into your small intestine. The small intestine absorbs what you need, while the large intestine then absorbs the last of the minerals. The hard remain rests in your colon, where it then will exit.
