The organ in which the bulk of chemical digestion and absorption of food occurs.
The first portion of the small intestine; the duodenum receives the chyme from the stomach and mixes it with digestive secretions from other organs
An organ that helps digestion by producing enzymes (lipase) that act in the small intestine, secretes a juice that neutralizes acidic chyme.
Aids digestion by producing bile salts and emulsifying fats.
Chemicals produces by the liver an stored by the gallbladder that emulsify fats s they can be chemically digested by enzymes
To break up large fat globules into small fat droplets that can be more efficiently chemically digested by enzymes.
Organ that stores bile salts and releases them as needed into the small intestine.
A fat-digesting enzyme active in the small intestine
cells that line organs and body cavities; in the digestive tract to absorb nutrients.
The uptake of digested food molecules by the epithelial cells lining the small intestin
Finger-like projections or folds in the lining of the small intestine that are responsible for nutrient absorption and water absorption
Remaining water is absorbed and solid stool is formed.
The first and longest portion of the large intestine, water absorption.
Solid waste material eliminated form the digestive tract.
A hernia occurs when an organ pushes through an opening in the muscle or tissue that holds it in place.
