Final answer:
The process not associated with the digestive system is perspiration, which is the body's method of regulating temperature through sweat.
Step-by-step explanation:
The process that is NOT a digestive process is C. perspiration. The digestive processes include ingestion, which is the intake of food through the mouth; propulsion, which moves food through the digestive tract; mechanical digestion, which involves physically breaking down food; chemical digestion, which involves chemically breaking down food into simpler molecules; absorption, which is the uptake of nutrients into the bloodstream; and defecation, which eliminates undigested food from the body as feces. Perspiration, on the other hand, is the process by which the body sweats to maintain temperature regulation and is not part of the digestive system.
