Digestion Process

1) How Does the Food We Eat Change After Getting Digested?

• After digestion is over, the food gets converted into simple nutrients, which are absorbed into the bloodstream through the walls of the small intestine.
• Carbohydrates, fats, and proteins change into glucose, glycerol, and amino acids, respectively.

2) Our Stomach Secretes an Acid Called Hydrochloric Acid, Which Is Highly Corrosive, but Our Stomach Is Not Affected by It. Can You Explain Why?

• The mucous layer covers the wall of our stomach.
• It secrets mucous, a slimy liquid that lubricates the walls of the stomach, thereby protecting the stomach from the action of hydrochloric acid.

3) Once the Food Is Digested in the Stomach, It Is Delivered Slowly and in Small Quantities to the Small Intestine. Why Do You Think This Arrangement Is Adapted?

• After the digestion process is partially completed in the stomach, the food is further passed in small quantities to the small intestine for complete digestion.
• The completely digested food then passes slowly through the walls of the small intestine for its complete absorption into the bloodstream.
