  • Digestion
    • Lipase breaks down fat into fatty acids and glycerol in the small instestines
      • Bile is released from the gall bladder to emulsify fats, increasing surface area for efficient digestion
        • Fat diffuses through the small intestine into the lymph
    • Carbohydrate-s and protein molecules are soluble, diffuse into the blood
    • Small intestine adaptations: villi and microvilli, many blood cappilaries, large surface area
    • Protease breaks down protein into amino acids in the stomach- acid is the optimum for protease (low pH)
    • Carbohydrase breaks down starch into sugar (glucose) in the mouth
      • Starch to moltose, moltose to glucose
    • Physical digestion-allows food to pass through the digestive system easily
