Question

Define ingestion
Define Digestion
Define Absorption

Answer 1

• Ingestion refers to the entry of substances into the body through swallowing. Ingestion of substances may result from the swallowing of mucus that has been contaminated through inhalation or when eating, drinking, biting fingernails or smoking
• Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
• Absorption, in general sense, is the act or process of absorbing or assimilating. In biology, absorption pertains particularly to the process of absorbing or assimilating substances into the cell or across the tissues and organs. It is done through diffusion or osmosis.
