Match the following digestive process with the correct description: Mechanical digestion

a) Use of enzymes to break down food
b) Physical breakdown of food into smaller particles
c) Absorption of nutrients in the small intestine
d) Movement of food through the digestive tract

Answer 1

Mechanical digestion matches with description (b) which is the physical breakdown of food into smaller particles, primarily occurring in the mouth and stomach.

Step-by-step explanation:

To match the digestive process with the correct description, we should understand what each term means. Mechanical digestion refers to the physical breakdown of food into smaller particles. This process begins in the mouth with chewing and continues in the stomach as the food is mixed with digestive juices.

The correct match for mechanical digestion is:

Mechanical digestion (b) Physical breakdown of food into smaller particles

Here are the descriptions for the other processes, even though this is outside of the mechanical digestion scope:

• Use of enzymes to break down food (a) Chemical digestion
• Absorption of nutrients in the small intestine (c) Absorption
• Movement of food through the digestive tract (d) Peristalsis/Ingestion
