mechanical and chemical digestion Flashcards
organisation (10 cards)
what is the type of reaction that occurs between an acid and alkali
neutralisation recation
function of large intestine?
absorb water in the bloodstreams
what is mechanical digestion?
physical action that make the chunks of food smaller
what is chemical digestion?
consists in enzymes that convert insoluble molecules into soluble molecules
is bile an acid or alkali?
alkali
emulsification
bile emulsifies fats as they do not dissolve in water meaning its harder for fats to travel through the digestive system. this increases the surface area for more chemical reactions
give two functions of hydrochloric acid in the digestive system:
1- neutralises ph scale in our stomach
2- it kills microorganisms that can produce diseases
give two functions of the bile in the digestive system:
1- neutralises hydrochloric acid as bile is an alkali
2-emuslifies fats turning them into smaller molecules and increasing the surface area
what are the two types of digestion?
chemical and mechanical digestion
name the tissue that allows for mechanical digestion in the stomach:
muscular tissue
