Chapter 18 food and digestion

The process by which nutrient molecules pass through the wall of the digestive system and into the blood is called blank

Absorption

What are vitamin

Act as helper molecule in a variety of chemical reaction

What occurs during chemical digestion in the mouth

The muscular opening through which wastes are removed from the body

Anus

The food contain high amount of protein

Beans

Then, molecules are absorbed into the blank and carried throughout the body

Blood

Food

What is digestion

Food are digesting by which the body breaks down food into smaller nutrients molecules

Three jobs that fats have in body

Form part of structure of cells, they protect your internal organs, and acts as insulation to keep insulation

It can alert you to substance that have been added to the food that could make you sick

Why is water the body's important nutrient

It is the most important nutrients because the body': vital process including chemical reaction take place in water

What happens to the materials that are not absorbed

These materials are removed from the body as wastes

List three ways in which proteins are used by the body

Tissue growth, play part in chemical reaction within cells and can serve as a source of energy

True or False: Nutrients molecules past from the small intense feed on the material passing through and make certain in the vitamins for the body
