Study Notes
Digestive System
Overview
- The digestive system is a complex process by which the body breaks down and absorbs nutrients from food.
- It consists of the alimentary canal (mouth, esophagus, stomach, small intestine, and large intestine) and accessory organs (liver, pancreas, and gallbladder).
Functions
- Ingestion: mechanical breakdown of food in the mouth
- Digestion: chemical breakdown of food in the stomach and small intestine
- Absorption: uptake of nutrients into the bloodstream in the small intestine
- Elimination: removal of waste products from the body through the anus
Organs and Their Functions
-
Mouth:
- Mechanical breakdown of food by teeth
- Saliva production for lubrication and enzymatic breakdown
-
Esophagus:
- Muscular tube that propels food to the stomach
-
Stomach:
- Mechanical churning and mixing of food with digestive enzymes
- Acidic environment for protein denaturation
-
Small Intestine:
- Most absorption of nutrients occurs here
- Villi and microvilli increase surface area for absorption
-
Large Intestine:
- Water and electrolyte absorption
- Storage and elimination of feces
-
Liver:
- Production of bile for fat emulsification and absorption
- Detoxification and metabolism of nutrients
-
Pancreas:
- Production of digestive enzymes for carbohydrate, protein, and fat breakdown
-
Gallbladder:
- Storage and release of bile into the small intestine
Digestive System
Overview
- The digestive system involves the breakdown and absorption of nutrients from food, comprising the alimentary canal and accessory organs.
Functions
- Ingestion involves mechanical breakdown of food in the mouth.
- Digestion is the chemical breakdown of food in the stomach and small intestine.
- Absorption occurs in the small intestine, where nutrients are taken up into the bloodstream.
- Elimination is the removal of waste products from the body through the anus.
Organs and Their Functions
Mouth
- Teeth facilitate mechanical breakdown of food.
- Saliva production aids in lubrication and enzymatic breakdown.
Esophagus
- This muscular tube propels food to the stomach.
Stomach
- Food is mixed with digestive enzymes and undergoes mechanical churning.
- The stomach's acidic environment facilitates protein denaturation.
Small Intestine
- Most nutrient absorption occurs in the small intestine.
- Villi and microvilli increase the surface area for absorption.
Large Intestine
- Water and electrolyte absorption occur in the large intestine.
- This organ stores and eliminates feces.
Liver
- The liver produces bile for fat emulsification and absorption.
- It also performs detoxification and metabolism of nutrients.
Pancreas
- The pancreas produces digestive enzymes for carbohydrate, protein, and fat breakdown.
Gallbladder
- The gallbladder stores and releases bile into the small intestine.
