Digestive system

It is needed in order for food we eat to be broken down and digested effectively and nutrients from the food to be absorbed by the bloodstream to be transported to rest of the body parts for cellular respiration and energy generation for daily activities to take place

To attain proper nutrition we need to consume an appropriate amount of macronutrients - carbohydrates proteins and fats

carbohydrates is an essential macronutrient belonging from a family of biological a compounds consisting of carbon hydrogen and oxygen

Monosaccharides, disaccharides, polysaccharide these terms are for carbohydrates ONLY

The simplest nutrient molecule is a monosaccharide and the most complex nutrient molecule consisting of many molecule bonded together is a polysaccharide

Monosaccharides, also called simple sugars, are the simplest forms of sugar and the most basic units from which all carbohydrates are built.

When chemically combed in pairs monosaccharides form disaccharides Many monosaccharide units can be chemically combined in long chains forming polysaccharides

monosaccharides: Glucose Fructose Galactose Disaccharides Sucrose Lactose Maltose Polysaccharides Glycogen Starch Cellulose

proteins is an essential macronutrient for our body belonging from the biological family of compounds carbon hydrogen nitrogen and oxygen

Molecules own as amino acid chemically combine together in a chain to form polypeptides. Polypeptides then fold into a 3D shape to form a functional protein

fats is an essential macronutrient for our body belongs to a biological family of compounds carbon hydrogen and oxygen but in different ratios compared to carbohydrates

Some types of fats are formed when 1 glycerol to 3 fatty acids units chemically combine.

various classes of food is needed in appropriate amounts to reduce energy/raw materials for metabolic purposes However they should be consumed in small quantities to maintain a healthy body and they don’t have energy values in them

Iron Calcium Fibre Vitamin D/C

Fibre stimulates peristalsis and prevents constipation

helps our teeth and bone grow stronger

D: aids in calcium absorption C: helps our skin and gums to be healthy

Helps synthesise haemoglobin of red blood cells

Digestion is the process of complex nutrient molecules being broken down into small soluble and diffusible nutrient molecules to be easily absorbed into bloodstream
