Digestive System
Structures of The Digestive System
The Esophagus- The esophagus receives broken down food from the mouth and transports it to the stomach.
The Stomach- The stomach breaks down the food further through digestion. It secretes a strong acid that breaks down the food into a thick liquid.
The Small Intestine- Using enzymes the small intestine breaks down the food further and is responsible for absorption of nutrients into the bloodstream.
The Large Intestine- The large intestine absorbs the left over water and transports waste to the rectum once absorption is complete.
The Rectum- The rectum receives defecation from the colon.
The Pancreas- The pancreas secretes enzymes. These enzymes are responsible for the breakdown of proteins, fats, and carbohydrates.
The Liver- The liver secretes bile which is a substance that processes the blood from the small intestine containing the nutrients from digested food.
The Gallbladder- The gallbladder absorbs the left over bile secreted from the liver.
