difference in metabolic waste and undigested food
Answers
Answer:
Metabolic wastes or excrements are substances left over from metabolic processes (such as cellular respiration) which cannot be used by the organism (they are surplus or toxic), and must therefore be excreted. This includes nitrogen compounds, water, CO2, phosphates, sulphates, etc.
Explanation:
The presence of undigested food could indicate food is passing too quickly through the digestive tract and not being properly digested. See your doctor if you experience any of these symptoms: changes in bowel habits, such as loss of bowel control.
Answer:
Excretion is the removal of toxic materials, waste products of metabolism and excess substances from organisms. Egestion is the passing out of undigested food as faeces, through the anus. Three major organs of excretion are the skin, kidneys and lungs
