A) digestion, absorption, ingestion, and elimination
B) digestion, indigestion, absorption, and elimination
C) ingestion, indigestion, digestion, and elimination
D) ingestion, digestion, absorption, and elimination

Accepted Answer

The correct sequence of the four major processes of the digestive system is ingestion, digestion, absorption, and elimination. Ingestion refers to the intake of food, followed by its mechanical breakdown and chemical digestion in the digestive tract. Absorption then occurs in the small intestine, during which nutrients are transferred to the bloodstream. Finally, elimination occurs as undigested material is eliminated from the body through the rectum and anus. Option A correctly lists the processes in order, while options B and C have incorrect or missing processes.
