Unwanted food that the body cannot digest or absorb leaves the body primarily through the digestive system. After nutrients are extracted, the remaining indigestible parts are formed into waste in the large intestine and are eventually expelled from the body through the rectum as feces. This process helps maintain the body’s health by eliminating substances that are no longer needed.

How does food enter and leave the body?

when you bite into the food


What are examples of substances that enter or leave the body?

Examples of substances that enter the body include nutrients from food, oxygen from the air we breathe, and medications. Substances that leave the body include carbon dioxide when we exhale, waste products such as urine and sweat, and toxins removed by the liver.


How do oxygen and digestive foods get into your body cells?

Through the blood stream The "unwanted food" goes into your feces, while the rest goes into your blood stream. Each cell in your body needs a little energy. The cells have a neucleus and a covering, the food/energy that the cell needs is ingested into the cell while the unwanted items go to your feces, and if there is extra it goes into fat. Your body has fat to survive for the times where food is unavailable.


What body part uses every part of food you eat and all the waist goes to it and it drys out so it can leave your body?

I think the question relates to the ingestion, digestion, and the waste disposal of food we need to stay alive. Therefore, in one word, it is the digestive system.


What if your body can't use every part of the food you eat. The waste comes to me and I dry it out so it can leave your body. What am I?

You are the colon, which is part of the digestive system. Your primary function is to absorb water and nutrients from the food consumed while processing waste. The leftover material, or waste, is compacted and stored until it is expelled from the body.
