Which system of the body breaks down food into forms that the body can use?
excretory system
digestive system
reproductive system
respiratory system

The correct answer would be the digestive system.

The main function of the digestive system is to break down the complex food substances into simpler absorb-able form.

It is achieved by mechanical and biochemical degradation of the food.

The whole process of the digestive system can be classified into five steps ingestion, digestion, absorption, assimilation, and egestion.

Usually, polysaccharides are converted into monosaccharides (such as glucose), proteins are converted into amino acids, and fats are converted to fatty acids and glycerol.

carbohydrates are the body's preferred source of energy.

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
