Frequently Asked Questions
Human digestion refers to the process through which food is broken down both mechanically and enzymatically, beginning from the mouth continuing through the esophagus to the stomach and intestines, where absorption of nutrients and elimination of waste occurs.
Digestion is dependent on enzymes since it is these that assist in the breakdown of bigger molecular structures such as carbohydrates, fats and even protein, into other smaller structures that can be taken up by the body.
The small intestine is lined with numerous tiny finger-like structures known as villi to facilitate and increase the surface area for absorption for better uptake of nutrients to the blood circulation.
Herbivores have a longer digestive tract to break down plant materials, which are harder to digest, whereas carnivores have a shorter, more acidic digestive system to efficiently digest meat.
