Digestion refers to the breaking down of large food molecules into smaller food molecules in the body.
So that small food molecules can diffuse through the walls and enter bloodstream.
Starch and proteins are large food molecules that cannot pass through the
walls.
Body needs energy to do work. Nutrients include
◦ Carbohydrates Provide energy (growth, warmth, movement)
◦ Proteins For growth and regeneration of cells and tissues Repair of damaged tissues. Source of energy if carbohydrates and fats unavailable
Nutrients include◦ Fats
Provide energy Two times that of carbohydrates
Nutrients help◦ in our growth, ◦ by keeping us healthy, ◦ by repairing our cells and tissues, ◦ by giving us energy.
Enzymes are used to digest food◦ Carbohydrase / Amylase
Carbohydrates to Simple sugars◦ Protease
Proteins to Amino acids◦ Lipase
Fats to Glycerol and Fatty acidsWhat has caused the decrease of enzymes available for use:-____________________________________________________________________
Alimentary canal consists of the ◦ Mouth (20sec)
Starch (carbohydrate) is digested to maltose by carbohydrase / amylase
◦ Esophagus (10sec) Walls of the alimentary canal are made of muscles which squeezes
food along the canal.◦ Stomach (2-6hrs)
Produces gastric juice which mixes food when stomach churns. Protease in the juice breaks down complex proteins into simpler
ones
Liver◦ Makes bile
Greenish liquid which emulsifies fats, breaking them into smaller droplets, easier for lipase to digest it.
Gall bladder◦ Stores bile made by the liver to breakdown FAT
Pancreas◦ Creates pancreatic juice
Flows to small intestine and contain enzymes
Small intestine (5hrs)◦ Produces intestinal juice which contains enzymes◦ Completes the digestion process with the help of the organs
joined to the alimentary canal (liver, gallbladder, pancreas)
Digestion ends at the small intestine:◦
◦ Small molecules of digested food passes through the small intestine wall, into the bloodstream surrounding it.
Digested food◦ Made of small food molecules
Diffuse through walls of small intestine Into blood vessels in walls Carried away by blood to the rest of the body Called absorption of food
◦ Blood carries the small food molecules to the cells of the body where they can be used.
Finger-like villi◦ Provides large surface area ◦ Folds the cell membrane
7 m-long small intestine◦ Increases surface area
One-cell thick small intestine◦ Shortens distance between wall and bloodstream
Alimentary canal consists of the◦ Large intestine and anus (24hrs)
Undigested food reaches the large intestine Lots of water is removed and taken back into the body Pass out through anus as feces
Nutrients in foods◦ Carbohydrates and fats are used for respiration and as
sources of energy.◦ Proteins are used for growth and the repair of body tissues.◦ Starch and glucose are two kinds of carbohydrates.
Why digestion is needed◦ Only small molecules are able to pass through cell
membranes into cells.◦ Starch, fat and protein molecules are too large to pass
through.
Meaning of digestion◦ Digestion is the breaking down of large food molecules in
the body into small food molecules.◦ The small food molecules are: glucose (from starch), amino
acids (from proteins) and glycerol and fatty acids (from fats).
◦ Digestion takes place by the action of enzymes.◦ Every cell in the body needs nutrients◦ Absorption-the circulation of nutrients in the body◦ Elimination—Undigested waste material◦ Digestion cannot occur without ENZYMES

what you digest and absorb.
The alimentary canal and digestion◦Mouth
Digestion of starch begins here.◦Stomach
Digestion of proteins begins here.◦Small intestine
Most digestion takes place here. Digestion of starch and proteins is completed here. Digestion of fats takes place only in the small intestine. Absorption
of digested food The small, digested food molecules are absorbed into the
bloodstream through the walls of the small intestine. The villi of the small intestine increase the surface area for faster
absorption of small, digested food molecules.
