Digestion of Food DEVELOPING YOUR NUTRITIONAL KNOWLEDGE

DIGESTION

BOARD NOTES: The digestive system converts food into small molecules that can be used by body cells. Food is processed by the digestive system in four phases: ingestion, digestion, absorption, and elimination. Ingestion is the process of putting food into your mouth.

Mechanical digestion is the physical breakdown of large pieces of food into smaller pieces.

During chemical digestion, enzymes break down food into molecules the body can use.

Food molecules are absorbed into the circulatory system by cells in the small intestine. Materials the body cannot digest travel through the large intestine and are eliminated as feces.

ACTIVITY #2: Complete the table on page 4 of your booklet, outlining the function of each organ in the digestive system. Use the information in your text to assist you and research the enzymes released at each organ (if any) and what their function is.

ACTIVITY #3: Use your text, the internet and what you already know, to complete the crossword on digestion on page 5 of your workbooklet.

HOMEWORK #1: Watch the video above called Mechanical and Chemical digestion and use the information in this video to answer the questions on page 6 of your workbooklet.

DID YOU KNOW: That 1.7 litres of saliva is produced every day. That's a lot of spit!
