How food travels through the digestive system 10 steps?
How food travels through the digestive system 10 steps?
The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation. Some chemical digestion occurs in the mouth.
What is the movement of food through the digestive tract called?
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
What are the steps of digestion describe each?
The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation.
How do you examine your digestive system?
Esophagogastroduodenoscopy (also called EGD or upper endoscopy). An EGD (upper endoscopy) is a procedure that allows the healthcare provider to examine the inside of the esophagus, stomach, and duodenum with an endoscope. This is guided into the mouth and throat, then into the esophagus, stomach, and duodenum.
What are the four stages of digestion?
The digestive system is composed of the mouth, pharynx, esophagus, stomach, small intestine, large intestine (or colon), rectum, and anus. There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food.
Where does food go on its journey through the digestive system?
From dinner plate to elimination, the food you eat takes a long trip through your digestive system. Take a look at the path your food will follow as it is digested: Mouth >> Esophagus >> Stomach >> Small Intestine >> Large Intestine At each step along the digestive journey, food is modified and broken down into usable pieces.
Which is the first part of the digestive system?
The digestive system is essentially a series of long, hollow organs lined with muscles that contract in a rhythmic pattern, known as peristalsis, to keep food moving in the correct direction. The mouth is considered the first part of the digestive system because food is physically broken down there by chewing.
How does saliva help the passage of food through the digestive system?
Saliva also contains mucus that helps ease the passage of food through the digestive system. Once chewing (mastication) and amylase digestion are complete, the food will have become a small round blob, which is known as a bolus. After swallowing, the bolus enters the esophagus and is moved down to the stomach through a process called peristalsis.
How does the tongue move through the digestive system?
The movement of the tongue is also important in the digestive process. After food is chewed up and mixed with saliva, it’s ready to be swallowed. Your tongue molds and mashes food into a bolus and guides it to the back of your throat. As you swallow, the bolus of food is pushed through the pharynx and into the esophagus.

Which is part of the digestive system produces more saliva?
More saliva is produced. It contains substances including enzymes that begin the process of breaking down food into a form your body can absorb and use. Chew your food more — it also helps with your digestion. Also called the throat, the pharynx is the portion of the digestive tract that receives the food from your mouth.
How are the processes of the digestive system regulated?
Chapter Review. The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation. These processes are regulated by neural and hormonal mechanisms.
