Digestive Organs

organs involved in digestion, including the esophagus, the stomach, small and large intestine, liver, and pancreas.

The parts of the digestive system

the mouth, the esophagus, the stomach, and the intestines

Function of the esophagus

to take food from mouth to stomach by muscular action called peristalis which helps in swallowing, a ride that will take about 5-8 seconds.

What is the lower esophageal sphincte

It is a ring-like muscle that relaxes when the food reaches the end of the esophagus and lets the food pass into the stomach.

Functions of the stomach

stores food, mix food with juice, kill bacteria in food.

Function of the small intestine

to further digest food through enzymes and absorb nutrients into the bloodstream.

Function of the large intestine

to absorb water and electrolytes from indigestible food matter and to form and store waste.

Function of the liver

to detoxify chemicals, metabolize drugs, and produce bile for digestion.

The process of digestion takes longer for some types of foods than others. How long does it take for each type of food to be digested?

simple carbohydrates, such as an energy drink breakdown the fastest. proteins take longer to digest, and fats take the longest time of all.
