الانزلاق: 1
Amber is hungry, so she goes to a store to buy some food.
الانزلاق: 2
What would you like?
I'll go for a turkey sandwich with lettuce and tomato.
She decides to order a turkey sandwich.
الانزلاق: 3
Amber takes a bite. First the food is chewed which breaks it up into smaller pieces. The turkey sandwich is also mixed with saliva that contains enzymes.
الانزلاق: 4
The partially digested food, known as a bolus, then passes through a tube called the esophagus. A muscular wave-like motion called peristalsis moves the bolus down the tube.
الانزلاق: 5
The bolus reaches the end of the tube and lands in the stomach. The bolus is mixed gastric juices to make a thick liquid called chyme.
الانزلاق: 6
The bolus then passes through the stomach to the small intestines. There, the chyme is mixed with enzymes and bile to help further break down the food.
الانزلاق: 7
Enzymes are produced in the pancreas. Bile is produced in the liver and stored in the gall bladder.
الانزلاق: 8
As the food moves along the small intestines, some of the nutrients are absorbed into the blood.
الانزلاق: 9
The food then passes into the large intestines where water is reabsorbed. What is left is food that can't be digested known as feces. Feces leave the alimentary canal through the anus.
