Mechanical And Chemical Digestion Flashcards
Hydrochloric acid meaning/ function
Gastric juices breaks down the food and the digestive enzymes splitting them up the protein and kills bacteria
Enzymes meaning/ function
It is protein that your body makes to break down food and aid digestion
Protein meaning/ function
The body digestion system breaks down dietary protein into amino acids, which are absorbed and used by cells to build other proteins.
Carbohydrates meaning/ function
Provide the body with energy. Comes from starchy foods.
Fats meaning/ function
Fats are a type of lipid that is vital for health provide energy, cushion organs and helps cells grow
Mechanical digestion meaning/ function
Involves physically breaking down food substances into smaller particles to more efficiency to undergo chemical digestion.
Chemical digestion meaning/ function
Uses certain enzymes to break down nutrients, such as carbohydrates, proteins and fats into smaller molecules.
Absorb meaning/ function
Occurs when small intestine breaks down certain nutrients that are then absorbed into the blood stream.
Amylase meaning/ function
Digestive enzyme predominantly secreted by the pancreas and salivary glands and found in other tissues at very small levels
Protease meaning/ function
Breaks down proteins into amino acids
Lipase meaning/ function
Breaks down lipids in the diet tiny fatty acids and glycerol
Pepsin meaning/ function
Breaks down proteins into smaller peptides and amino acids that can be easily absorbed by the small intestine.
Emulsify meaning/ function
Breaks down fat molecules.
(Mechanical digestion)
What happens in the buccal cavity during mechanical digestion?
Jaw moves the food around and teeth grind the food into smaller pieces (mastifaction)
Mouth is then moistened with saliva to make is easier to swallow.
(Mechanical digestion) what happens in the stomach during mechanical digestion?
Stomach churns good to get the food is squeezed down the oesophagi us
