Describe the 4 major activities of the digestive system. - correct answer 1-Motility: Movement of the digestive tract that are necessary for transporting the food and its digestive residues from one end to the other. 2-Secretion: Carried out by exocrine glands. 3-Digestion: Process whereby large molecules are converted into smaller ones. 4-Absorption: The products of digestion are transferred to the blood or lymph, for distribution to the cells of the body. List the forms to which the t...

Nutrition definition - correct answer the process of providing or obtaining the food necessary for health and growth. Digestion definition - correct answer It is the catabolic process that breaks down large food molecules to monomers (chemical building blocks) -carbohydrates—> monosaccharide -proteins—> amino acids -lipids—> fatty acid, Glycerol -nucleic acids—> nucleotide *the enzymatic breakdown of any food molecule is HYDROLYSIS bc it involves adding a wate...
