Answer 2

Nutrition In Human Beings is autotrophic nutrition. Nutrients are the substances in food that maintain the body and make it work. Most of what one eats is made up of carbohydrates, proteins, and fats.

Six essential nutrients are:

• Carbohydrates
• Vitamins and Minerals
• Fats
• Proteins
• Water
• Digestion

In digestion

• Ingestion: It is the process of us ingesting the food by actually eating it. In the mouth the food material is subject to cutting, tearing, chewing, and a little bit of pre-digestion using the salivary juice and finally swallowing.

• Digestion: It is the breakdown of the ingested food into microscopic and finally molecular fragments. Most of the digestion happens in the stomach and a small part of it also occurs in the small intestine.

• Absorption: This is a critical stage where nutrients are taken up from digestive organs and distributed to the body’s tissues. This process is where food ingested is converted to actual energy to be used by our bodies.

• Excretion: This is the final process where waste material is excreted from our bodies.
