Question

How can we add details about ingestion and excretion in the above flowchart?​

Answer 1

Answer:

Ingestion – the taking in of food

Food is taken into the mouth where it is physically broken down by the teeth into smaller pieces. The presence of food in the mouth triggers a nervous reflex that causes the salivary glands to deliver a watery fluid called saliva to the mouth.

Excretion is a process in which metabolic waste is eliminated from an organism. ... These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes.
