Is it not weeds.................
Answer:
There are several different ways to name it, but I always go by absorption, digestion, and metabolism/breakdown.
Explanation:
Absorption is the uptake of minerals, vitamins, and nutrients from your diet and your ingestion of water or other liquids. Absorption primarily takes place in the small intestine and anything that isn't necessary and vital for human life is then excreted through the urinary tract as urine and the remainder of the digestive tract as waste/feces.
Digestion is the process that occurs in the digestive tract which breaks down all food intake by mechanical and enzymical (stomach/gastric acid) processes in order to provide the body with all of the nutrients and minerals it needs to survive.
Metabolism is the breakdown of acids, fats, and enzymes within the organs in order to maintain life and promote production of energy. A healthy diet, cardiovascular exercise for 4-5 days a week, and maintaining good health in general is best to maintain a high metabolism and produce the most energy.
