Here is an annotated diagram of the human digestive system along with explanations of the functions of its parts:

Annotated Diagram of the Digestive System

Functions of Digestive System Parts

• Mouth: Initiates digestion through mechanical breakdown by teeth and chemical breakdown by saliva.
• Pharynx: Facilitates swallowing and directs food towards the esophagus.
• Esophagus: Transports food to the stomach using peristaltic movements.
• Stomach: Mixes food with gastric juices for further breakdown; acts as a temporary storage site.
• Small Intestine: Main site for digestion and absorption; utilizes enzymes from the pancreas and bile from the liver.
• Liver: Processes nutrients; produces bile for fat digestion; detoxifies substances.
• Gallbladder: Stores bile until needed for fat digestion in the small intestine.
• Pancreas: Produces digestive enzymes; regulates blood sugar through insulin secretion.
• Large Intestine: Absorbs water; compacts waste into feces for elimination.
• Rectum: Stores feces prior to excretion.
• Anus: Controls the expulsion of feces from the body.
