What are peristalsis inhibitors and what do they do?
Peristalsis inhibitors are substances that decrease the rhythmic contractions of the smooth muscles in the gastrointestinal tract, effectively slowing down or stopping peristalsis—the wave-like movements that propel food through the digestive system. These inhibitors can be useful in treating conditions such as diarrhea or gastrointestinal spasms. Common examples include certain medications like anticholinergics and opioids, which can help alleviate symptoms by reducing motility in the intestines. However, their use must be carefully managed, as excessive inhibition can lead to complications such as constipation.
How does bile help indigestion what does it helps to break down?
Bile is a product of the liver and its' function is to make large bits of fat much smaller. This gives a larger surface area for the enzyme lipase to break down the fats. The act of making large fat particles smaller is called emulsification.
Digestion begins in the mouth, where food is mechanically broken down by chewing and mixed with saliva, which contains enzymes like amylase that start the chemical process of breaking down carbohydrates. As food is swallowed, it travels down the esophagus to the stomach, where it is further digested by gastric acids and enzymes. This initial phase prepares the food for more extensive digestion and nutrient absorption in the small intestine.
Small intestine is to nutrient absorption as blood is to nutrient?
The small intestine is to nutrient absorption as the blood is to nutrient distribution.
What is the function of the mucus lining in the esophagus?
It lubricates the esophagus and assists in swallowing.
How do you decide the right answer when a question asks is the following true or false?
Every true-false questions contain one or two options. Often the wording is complex or a teacher tries to make it harder to trip you up. So you need to read the question very carefully! If it contains many pieces, mark a T right above anything that you KNOW is true. Draw a light line through anything you KNOW is false. Re-read it again. Weigh what you know is true against what you know is false, using your T and F markings. Then, make your decision. Don't second guess yourself!
Example: Is it true or false that food enters the stomach before it enters the esophagus where peristalsis helps it move through the intestines.
TIP: The order of events is wrong there! Food enters the esophagus, then the stomach, then the small intestines. The esophagus and intestines both use peristalsis but the question is still out of order. Answer is False.
Example: Is it true that cold air rises so it can get closer to the sun.
TIP: Wrong facts! Warm air rises; cold air stays lower. Getting closer to the sun has nothing to with this scientific fact about warm air.
Example: Is is true or false that 19 milligrams is equal to 19 milliliters?
TIP: Wrong thinking! You cannot mix those two types of conversion units.
What does saliva do to an apple?
Enzymes in saliva will start to break down the apple such as amylase which will break carhohydates into simple sugars
What is the system in your body that breaks down food into energy for your body?
From what I understand...the mouth with saliva is the initial process of the digestive tract. From that point enzymes and stomach acid break food down further. Once it begins moving through the intestines it's broke down and dispersed accordingly. All carbs break down into glucose (sugar) it flows through the blood. Your cells convert sugar to energy by use of insulin, which is created by the pancreas. Imagine insulin as the cells key to unlocking the energy!

Which digestion amylase causes?
Amylase is an enzyme that catalyses the hydrolysis of starch into sugars.
From where can one purchase a complete PA system?
Public Address systems can be purchased from stores that sell musical equipment or general electronics, like Guitar Center or Radio Shack. Additionally, PA systems can be purchased online from websites like Galls, Pro Audio Gear, and Carvin Guitars.
Where can someone find the medical terminology on the process of the human digestive system?
There are many places where one can find the terminology on the process of the human digestive system. One can find this information on the human digestive system Wikipedia page. One may also find this information through many different medical related websites.
Will a typical household refrigerator freezer freeze cold enough to kill the parasites in salmon?
A good deep freeze will kill most parasites. There are a few species that can have eggs survive freezing but are killed with thorough cooking.
I wouldn't smoke infested salmon. Not enough heat to kill the eggs.
Yes, humans can digest amylose, which is a component of starch. The digestion process begins in the mouth with the enzyme salivary amylase, which breaks amylose down into smaller sugar molecules. In the small intestine, pancreatic amylase further continues this process, ultimately converting amylose into glucose, which the body can absorb and use for energy. However, humans cannot digest amylose directly; it must first be broken down into simpler sugars.
What is the best over-the-counter alternative to Maalox for heartburn acid indigestion etc?
The easiest answer is - ask your pharmacist to recommend an alternative. If you're allergic to any of the ingredients in Maalox - your pharmacist will be able to recommend a subsitute medication that doesn't contain the substance you're affected by.

Is appetite The physical need for food?
Appetite is a complex sensation. It has mostly to do with nutrition for the body, so it is for physical reasons. But, there is a strong emotional component because we associate feeling full, or content, can be confused with other things in life that also need satisfying. So, people may develop eating disorders due to psychological reasons that have less to do with feeling full than they do of feeling complete as a person.
Which endocrine organ has a digestive function?
The endocrine capacity of the pancreas is best known for its secretion of insulin, a hormone. The pancreas, however, also has many digestive capabilities in that it secretes many enzymes needed for digestion of nutrients. The majority of the pancreas is exocrine tissue producing digestive enzymes and bicarbonate to digest and neutralize the chyme in the duodenum. The endocrine glands of the pancreas are the Islets of Langerhans, which only make up about 1 to 2 percent of the pancreas' mass. However, these Islets are very important and critical to the health of a human since they produce glucagon (alpha cells), insulin (beta cells), and somatostatin (delta cells). Glucagon and insulin are critical enzymes for maintaining a constant blood sugar level. Somatostatin, as the name suggests, stops body growth in general.
The stomach, pancreas, duodenum, and liver all can be categorized as in the digestive and endocrine system.
