A group of organs that digest and absorb nutrients from food.

A series of hollow organs that process food from mouth to anus.

The entry point of food into the digestive system.

A tube connecting the mouth to the stomach.

A muscle that controls the passage of food from esophagus to stomach.

Organ that mixes and breaks down food.

The organ where most nutrient absorption occurs.

The wave-like muscle contractions that move food through the GI tract.

The pancreas produces enzymes that break down carbohydrates, fats, and proteins in food.

Saliva lubricates food, making it easier to swallow, and contains enzymes like amylase to start digesting starches. It also cleans the mouth.

A chewed food mass mixed with saliva, ready to be swallowed.

The tongue has taste buds that detect salt, sweet, sour, and bitter tastes.

The tongue moves food around during chewing, helping to mix it with saliva for initial digestion.

Mixes food and liquid with digestive juices, and slowly empties contents into the small intestine.

The longest part of the GI tract, absorbing nutrients and water from digested food.

Absorbs water, changes waste to stool, and moves stool to the rectum.

Stores stool until it's eliminated from the body.

Carries bile from the liver to the gallbladder for storage, or to the small intestine for use in digestion.

Produces bile, a digestive fluid that helps with fat and vitamin digestion.

Stores bile between meals and releases it into the small intestine when needed.

Produces digestive juices that help with digestion in the small intestine.

An adult human has 32 teeth.

Connects the pharynx to the stomach, moving food by peristalsis.

Digests protein using enzymes.

Churns food with gastric juices.

Kills bacteria by producing acid.

Approximately 7 meters (about 23 feet) long.

The small intestine has 3 parts: the duodenum, jejunum, and ileum; and is made of 4 layers (muscular, blood vessels and nerves, submucous, and mucous layers).

Wave-like muscle contractions that move food through the digestive tract.

Pancreatic juice contains enzymes to digest carbohydrates, fats, and proteins.

Gastric juice contains enzymes mainly for digesting proteins and acid to neutralize bacteria.

Enzymes speed up chemical reactions in living organisms.

Amylase is a digestive enzyme that breaks down starch into maltose.

Tiny, hair-like projections that increase the surface area for nutrient absorption in the small intestine.

The large intestine is made up of the cecum, colon, appendix, rectum, and stores and expels waste products.

Bile emulsifies fats, breaking them into smaller droplets to aid digestion.

Intestinal juices contain enzymes that break down disaccharides into monosaccharides and polypeptides into amino acids.

An autoimmune disorder triggered by eating gluten, a protein.

Hard, dry poops due to slowed bowel movements.

Loose, watery poops, a common gut issue.

Conditions with pouches (diverticula) in the colon.

Viral infection of the stomach and intestines (stomach flu).

Chronic inflammation of the digestive tract, including Crohn's and ulcerative colitis.

Functional digestive disorder causing abdominal pain, bloating, and changes in bowel movements.

Stones formed in the gallbladder from bile components.
