Study Notes
Digestive System
The digestive system is a group of organs that work together to break down and absorb food, and eliminate waste.
Functions:
- Ingestion: taking food into the body
- Mechanical digestion: breaking down food into smaller pieces
- Chemical digestion: breaking down food into nutrients using enzymes
- Absorption: absorbing nutrients into the bloodstream
- Elimination: removing waste products from the body
Organs:
-
Mouth:
- Mechanical digestion: chewing food
- Chemical digestion: salivary enzymes break down carbohydrates
-
Esophagus:
- Transports food from the mouth to the stomach
-
Stomach:
- Mechanical digestion: churning food
- Chemical digestion: gastric enzymes break down proteins
-
Small intestine:
- Absorption: nutrients absorbed into the bloodstream
- Chemical digestion: enzymes break down carbohydrates, proteins, and fats
-
Liver:
- Produces bile to aid in fat digestion
- Detoxifies the blood
-
Pancreas:
- Produces digestive enzymes
- Regulates blood sugar levels
-
Large intestine:
- Absorption: water and electrolytes absorbed
- Elimination: waste products eliminated from the body
Accessory organs:
- Gallbladder: stores and releases bile
- Salivary glands: produce saliva to aid in digestion
- Appendix: functions unknown, thought to be vestigial
Digestive System
- The digestive system is a group of organs that work together to break down and absorb food, and eliminate waste.
Functions
- The digestive system performs five main functions: ingestion, mechanical digestion, chemical digestion, absorption, and elimination.
Organs
Mouth
- The mouth performs mechanical digestion through chewing food.
- The mouth also performs chemical digestion through salivary enzymes that break down carbohydrates.
Esophagus
- The esophagus transports food from the mouth to the stomach.
Stomach
- The stomach performs mechanical digestion through churning food.
- The stomach performs chemical digestion through gastric enzymes that break down proteins.
Small Intestine
- The small intestine absorbs nutrients into the bloodstream.
- The small intestine performs chemical digestion through enzymes that break down carbohydrates, proteins, and fats.
Liver
- The liver produces bile to aid in fat digestion.
- The liver detoxifies the blood.
Pancreas
- The pancreas produces digestive enzymes.
- The pancreas regulates blood sugar levels.
Large Intestine
- The large intestine absorbs water and electrolytes.
- The large intestine eliminates waste products from the body.
Accessory Organs
Gallbladder
- The gallbladder stores and releases bile.
Salivary Glands
- The salivary glands produce saliva to aid in digestion.
Appendix
- The appendix has unknown functions, but is thought to be vestigial.
