10.1 - The Roles of Water in our Body
• Flushing toxins from cells
• Lubricating tissues and joints

• A muscular, J-shaped organ in food is temporarily stored while further chemical & mechanical digestion takes place
10.2 Stomach
• A muscular, J-shaped organ in food is temporarily stored while further chemical & mechanical digestion takes place
• Stomach is lined up with millions of gastric glands that secrete gastric juice – a mixture of water, salt, and acids that help stomach digest food
• What helps break down proteins? Not Pepsi .. But ..
10.2 Stomach
• A muscular, J-shaped organ in food is temporarily stored while further chemical & mechanical digestion takes place
• Stomach is lined up with millions of gastric glands that secrete gastric juice – a mixture of water, salt, and acids that help stomach digest food
• Pepsin – enzyme in gastric juice that helps break down proteins
10.2 Stomach
• A part of the alimentary canal where digestion is completed – it breaks down nutrient macromolecules into molecules
10.2 Small Intestine
• A part of the alimentary canal where digestion is completed – it breaks down nutrient macromolecules into molecules
10.2 Small Intestine
• Nutrients are absorbed through membranes and they pass from the digestive system into the circulatory system which carries nutrients to cells & tissues throughout the body
• A part of the alimentary canal where digestion is completed – it breaks down nutrient macromolecules into molecules
10.2 Small Intestine
• Nutrients are absorbed through membranes and they pass from the digestive system into the circulatory system which carries nutrients to cells & tissues throughout the body
• Small intestine has 3 components
10.2 Small Intestine
• Small intestine has 3 components
10.2 Small Intestine
A short U-shaped part in which food passes from the stomach
• Small intestine has 3 components
10.2 Small Intestine
A short U-shaped part in which food passes from the stomach
Breaks down remaining proteins & carbs
• Small intestine has 3 components
10.2 Small Intestine
A short U-shaped part in which food passes from the stomach
Breaks down remaining proteins & carbs
Absorbs nutrients & pushes undigested material into large intestine
• Pancreas: secretes about 1 L of pancreatic fluid into duodenum everyday
• Pancreatic fluid contains - enzymes that chemically digest carbs, lipids & proteins
- bicarbonate that alters pH to maximize enzyme efficiency
• Liver: largest internal organ inside us (size of a football) and its main digestion-related secretion is bile
• Bile: a greenish-yellow fluid secreted by the liver to help digest fat
• Bile is then sent to the gall bladder which stores bile between meals
