Question

7 what is a function of the digestive system? multiple choice 6.42 ingests and breaks down food, absorbs nutrients, and defecates the unabsorbed material sends cellular debris to lysosomes mechanically and chemically assembles food from absorbed nutrients absorbs nutrients in the mouth, pharynx, esophagus and stomach, and releases nutrients in the intestines.

Explanation:

The digestive system's main functions are to ingest food, break it down (both mechanically and chemically), absorb nutrients, and eliminate undigested material. Lysosomes are part of cells (not the digestive system's role regarding them). Assembling food from nutrients is not a digestive system function. Nutrient absorption mainly occurs in the small intestine (not the mouth, pharynx, esophagus, and stomach for significant absorption).

Answer:

Ingests and breaks down food, absorbs nutrients, and defecates the unabsorbed material.
