Is it true that human have holozoic mode of  nutrition?

The above given statement is true.

• Humans have holozoic nutrition, which means they ingest their food whole and digest it internally.

It can be described as follows:

• Food ingestion is the process by which food is ingested into the oral cavity. The teeth aid in the grinding of food, salivary amylase aids in the partial breakdown of starch, and the tongue aids in the mixing of food with saliva and then swallowing it. Bolus is the new name for the food.
• Digestion is the act of breaking down complex compounds into simpler things. It begins in the mouth, where the physical breakdown occurs along with some chemical digestion. The bolus is ingested and enters the stomach, where protein breakdown proceeds due to the presence of the enzyme pepsin. In this stage lolus is now refer as the chyme.
• This chyme is now moving towards the small intestine, where the rest of the digesting process will take place. Carbohydrates, lipids, and the remaining proteins will be broken down by pancreatic juice, intestinal juice, and bile.
•  The chyme is now known as the chyle, and it travels to the large intestine to be absorbed.
• Absorption- The digested food enters the bloodstream via the finger-like projections on the inner surface of the small intestine.
• Assimilation- The ingested food is subsequently used for energy generation by various tissues. Excess food is stored in the liver as glycogen and adipose tissue as fat.
• Undigested material moves from the small intestine to the rectum of the large intestine, where it is expelled from the body via the anus.

Hence, option A is the correct answer.
