What mechanical process move the bolus through the esophagus?
Peristalsis is the process of wave-like muscular contractions that moves food down the esophagus into the stomach.
Once it is in your throat,
peristaltic action
moves it up to your stomach
Which major organ is in the digestive and excretory?
If I remember my schooling they are the lungs, liver,kidneys and the skin. Each organ filters the blood to remove toxins.
Where in the human body would you find cells specialized to produce digestive enzymes?
Cells specialized to produce digestive enzymes are primarily found in the pancreas, specifically within clusters called acini. These acinar cells secrete digestive enzymes into the small intestine to aid in the breakdown of food. Additionally, specialized cells in the stomach lining, such as gastric chief cells, also produce digestive enzymes like pepsin.
What is peristalsis and segmental movements?
This the way the movement occurs in smooth muscle. Peristalsis occurs in the intestine. Segmental movements occur there also but in large waves.
What process breaks down food into smaller and useful materials?
Digestion is the process of changing food into a form that the body can absorb and use as energy or as the raw materials to repair and build new tissue. Digesting food is a two-part process that's half mechanical, half chemical.
- Mechanical digestion begins in your mouth as your teeth tear and grind food into small bits and pieces you can swallow without choking. The muscular walls of your esophagus, stomach, and intestines continue mechanical digestion, pushing the food along, churning and breaking it into smaller particles.
- Chemical digestion occurs at every point in the digestive system, beginning when you see or smell food. These sensory events set off nerve impulses from your eyes and nose that trigger the release of enzymes and other substances that will eventually break down food to release the nutrients inside. The body then burns these nutrients for energy or uses them to build new tissues and body parts.

What is The role of buffer in restriction digestion reactions?
I believe that it is used to stabilize the pH levels so the enzyme activity isn't effected.
Which phase of digestion occurs when you think about see or taste food?
A chemial change because during digestion carbohydrates are converted into simple sugar units,proteins into amino acids and so on, water and enzymes present in the body catalysed these reactions.
What does your body do with the end products of protein digestion?
After your digestive system breaks down protein through digestion, the amino acids are used to build other proteins. For example muscle.
Children and others find feces and jokes about it funny in part because of immaturity. But fecal matter is something universal that every person in every nation and culture knows about. It is something we even have in common with all other mammals.
What are the names of indigestion tablets?
See the link below.
It is not so correct to say the best tablets in this case; the drugs are very simple and independently on composition all are useful, of course without excess on long periods.
What organs secrete substances into the small intestine and what do they secrete?
well the villi are on the walls of the small intestine and they secrete pancreatic juice, made from the pancreas.
Chemical digestion is possible because of certain kinds of proteins called what?
The answer would be "Enzymes".
The key digesting enzymes include lipases (for lipids), proteases (for proteins). Other enzymes important is amylases, which digest certain types of sugars.
Why is mechanical digestion important for proper chemical digestion?
Mechanical digestion chops the food in to smaller pieces, thus exposing more of it to the enzymes of the chemical digestion.
Mechanical digestion begins in the mouth by the teeth, tongue and saliva. Mechanical digestion is important for chemical digestion because when food is broken down into smaller particles by mechanical means, chemical digestion will be more efficient.
What is the optimum shape for fecal matter?
Your Poop Needs To Be In An S Shape. That Means Your Healthy. Now I Know You Are Wonderin How Is That Possible But What I Mean Is That Is Does Not Need To Be Hard And In Little Balls. Gross Huh? But Its True.
What protect the stomach wall from acid?

Digestive problemswhat could be the cause?
There are a range of digestive problems that can be caused by many factors. Some digestive disorders are caused by an unhealthy lifestyle, stress, as a result of other illnesses or they may be hereditary.
How is the digestive system related to the skeletal system?
The blood from the circulatory system goes into the kidneys from the renal vein and then into the kidneys and then the nephrons which filter the blood of all the bad stuff like urine and urea.
Where is most of the digested food stored?
Digested food isn't really stored, it passes through the body at a steady pace.
It is Cholecystokinin (CCK)
What is the job the of digestive system?
The job of the digestive system is to break your food down,physically and chemically using the good bits I.E vitamins,carbs and stuff to help your body and excrete the bits it doesn't need.
How is acid produced in the mouth?
Bacteria consume residual food in the mouth and produce acids as by-products.
Where do the circulatory and the digestive system meet?
In the end of the small intestine. The illeum absorbs the nutrience and send into the blood system
Which part of the digestive system is primarily responsible for absorbing nutrients?
The small intestine is the part of the digestive system responsible for absorbing most of the nutrients. The villi are the structural feature that maximize surface area for absorption.
What makes your stomach growl and make you burp?
Lots of things could cause these symptoms. Sometimes, indigestion is the cause.
