Tag: Cellular ingestion

An amoeba ingests food particles through a process called phagocytosis, while a baleen whale filters tiny organisms from the water. This vast range of techniques illustrates the different methods of ingestion that exist across various domains, from cellular biology to advanced technology and environmental science.

The human digestive tract is approximately 30 feet long, a complex system where the process of ingestion begins but is not the same as the specific, intentional act of eating. While often used interchangeably in casual conversation, these two terms have distinctly different meanings, particularly in a biological context, encompassing far more than just sitting down for a meal.
