Where do the secretions that produce the alkaline condition in the small intestines originate?
It's the liver and gall bladder.... ;)
endothermic
How is food pushed down the gullet?
It's peristaltic action, sort of like squeezing water along a flexible hose.
What happens to food that is not digested in the small intestine?
It is passed along to the large intestine, where water and other substances are absorbed. Helpful bacteria in the large intestine can break down undigested materials into soluble forms, including some important vitamins.
Does the small intestine have mechanical or chemical digestion?
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
Can you pass gas on command by telling your body to pass gas?
Perhaps, if you have enough gas in the intestinal tract.
Does digestion start before peristalsis takes place?
Yes, digestion starts in the mouth, before peristalsis takes place. The mouth breaks up food, and starts the chemical digestion of starches.
Which parts of the digestive system aid in chemical digestion?
Is the stomach but begins in the mouth.
What organ of the digestive system has increased surface area?
The stomach which is lined with ridges called Rugae
the small intestines, lined with vili and micro-vili

If pepsin and trypsin had to function together what pH would produce the highest activity?

Can coffee cause a loss of appetite?
Yes and no. It's a much-loved and widely believed story that coffee is an appetite suppressant, and some people believe it helps them to lose weight. The truth is more nuanced: yes, drinking a cup of coffee can temporarily cause a loss of appetite by filling up your stomach, but the word to remember is "temporarily"-- it doesn't last very long, and drinking too much coffee can make a person anxious and jittery, due to the caffeine that coffee contains. But if you are asking whether there is a medical condition where coffee itself causes loss of appetite (not temporarily, and not intended to help a person lose weight), I have not heard of such a condition. I am sure there may be some people who have an allergic reaction to caffeine, but usually a loss of appetite is caused by other factors, and if you are not interested in eating, or cannot eat, I doubt coffee is to blame. You may want to see your doctor and have a physical exam to find out the actual cause and get the proper treatment for it.
How are a paper towel and the small intestine alike?
Both absorb something. A paper towel absorbs a waste liquid and our small intestine absorbs water and nutrients.
Hope this helped!:)
Why is lactase not found in stomach or large intestine?
this is because Lactase activity increase at a pH of 7 and 8 but at a pH of 7, the activity is maximum. At a pH above 7, the activity is decreasing. At a pH of 1 and 2, Lactase is inactive. Therefore, Lactase work best at a pH between 7 and 8.
