B3 Nutrients,Digestion And Enzymes Flashcards
Carbohydrates
.source of energy
.simple sugars (glucose) and complex carbohydrates (starch)
.found in foods like bread ,pasta,fruits and vegetables.
Protein
.Essential for growth and repair of tissues
.Made of amino acids
.sources Include meat,fish,eggs and beans.
Fats.
.High energy source and vital for cell membranes
.Fatty acids and glycerol are the building blocks
.found in oils ,butter and nuts
Vitamins and minerals
.vital for various bodily functions
.examples: Vitamin C (immune function) , iron (haemoglobin production).
Water
.essential for hydration and biochemical reactions.
Digestion
.purpose : Break down food into smaller,absorbable molecules
1.ingestion- Taking in food
2.digestion- Mechanical (chewing) and chemical breakdown (enzymes)
3.Absorption- Nutrients absorbed into the blood,primarily in the small intestines
4.Egestion- Elimination of undigested waste (feces)
Digestive system
.mouth- mechanical digestion (chewing) and chemical (saliva)
.Oesophagus- Transports Good to the stomach
.stomach- Gastric juices (acid & enzymes) break down & proteins
Small intestines- Major site car digestion and absorption
Large intestine- Absorbs water and forms feces
Recturn & Anus
. Recturn stores faeces ( undigested Waste)
.Anus releases it from the body (egestion)
