Ingestion
Usage Variability
Depending on context, 'ingestion' can imply various methods of intake, not limited to eating or drinking.

The ingestion of medication might involve inhalation as well as swallowing pills.
Not for Breathing
'Ingestion' specifically means taking in through the digestive system; it's not used for breathing.

The ingestion of oxygen isn't correct; instead, use 'respiration' or 'breathing.'
Usually Voluntary
Ingestion often implies a deliberate act, though it can be involuntary, like accidental poisoning.

The baby's accidental ingestion of the cleaner immediately prompted a call to poison control.
