What is the main function of the digestive system?

To transform food into nutrients and energy.

Name one body part that is NOT a main component of the digestive system, as described in the video.

Trachea/Lungs/Heart/Brain/Kidney/Spleen/etc.

Saliva moistens food to form a bolus and contains enzymes that begin breaking down starches.

A wave-like muscle contraction that moves food through the digestive tract.

Chyme is a frothy liquid produced in the stomach after the bolus is broken down by acids and enzymes.

I understand and can explain how food is digested in the digestive system.

1
The digestive system is comprised of ten organs covering nine meters and transforms food into nutrients and energy.
2
The gastrointestinal tract transports food, while the pancreas, gallbladder, and liver break down food using special juices.
3
After about three hours in the stomach, the bolus becomes a frothy liquid called chyme, which moves into the small intestine where fats are dissolved by bile.
