Describe the four basic digestive functions: motility, secretion, digestion, and absorption

What will be an ideal response?


Motility—muscular contractions that mix and move forward the contents of the digestive tract. Secretion—the production and delivery of juices into the digestive tract, consisting of water, electrolytes, and specific organic constituents. Digestion—biochemical breakdown of structurally complex foodstuffs into smaller, absorbable units. Absorption—small units resulting from digestion, and along with water, vitamins, and electrolytes are transferred from digestive tract lumen into blood or lymph
