GENERAL HISTOLOGY

Detailed explanation-1: -Peristalsis is a type of involuntary muscle movement that occurs in your digestive system. It begins in your throat when you swallow, and continues to propel food and fluids throughout your gastrointestinal tract.

Detailed explanation-2: -The involuntary muscle movement of the digestive system is called peristalsis. Peristalsis happens in our throats after we initially swallow our food. The food is moved down the esophagus by this involuntary muscle movement and delivered to the stomach.

Detailed explanation-3: -The first step in the digestive process occurs in the mouth. This is where food is chewed and broken down into a size that can be safely swallowed. The start of swallowing food or liquid is voluntary. But once it begins, the process becomes involuntary and continues under the control of the nerves.

Detailed explanation-4: -The stomach muscles churn and mix the food with digestive juices that have acids and enzymes. These juices help break up food into much smaller pieces.

Detailed explanation-5: -The type of muscle found in the digestive system is called smooth muscle. Smooth muscle is one of three major types of muscle tissue in the body. It lines hollow internal organs such as the stomach and intestines, as well as blood vessels.
