Is true the itestinal villi contains capillaries and lacteals for chemical digestion?
yes. every mucosal villi in the small intestine contains a venule(vein) and arteriole (artery) and a lymph vessel (specifacally lacteals).
The lacteals (lymph vessels) serve an important function in the absorption of fats and other nutrients.
The capillaires transport the products of digestion of dietary proteins and carbohydrates, and the lacteals transport those of dietary fats.

Changing your intestinal habits can be a bit tricky and to be honest I'm not really sure how to change them. But you could try eating at different times, if possible. Another thing you could try is to monitor how much fiber you eat, because fiber helps move bowel contents along. If you eat a lot of fiber, you could try eating less of it, or vice versa if you find that you don't eat much of it. Keep clear of foods like prunes, coffee, pears, high-fiber cereals and figs, as they tend to have a laxative effect once you eat them. I hope this helps you out a little!
Which part of digestive system serves as a mixing chamber and temporary reservoir for food?

What types of food particles are broken down by the pancreas?
The pancreas does not break down food particles. It is an acessory organ.
It does release some enzymes into the stomachthat aid digestion:
- pancreatic amylase - splits glycogen into disaccharides
- pancreatic lipase - breaks down triglycerides
- trypsin, chymotrypsin, and carboxypeptidase - digest proteins
- nucleases - digest nucleic acids
- bicarbonate ions - make pancreatic juice alkaline (the stomach is very acid).
How pneumonia affects the digestive system?
It affects the respiratory system. Not the digestive system. Your lungs are blocked by fluid.
Fats in foods break down into fatty acids and glycerols.
Why is noradrenaline used in the treatment of upper digestive tract hemorrhages?
this medication constricts the blood vessels, thereby decreasing/stopping the bleeding.
Compare mechanical digestion to chemical digestion?
mechanical digestion - chewing, mixing, churning
chemical digestion - breakdown of fat, carbohydrate and proteins by specific enzymes (lipases, amylases, and proteinases respectively)
Which bacteria are present in the small intestine that help in digestion in humans?
Well, let me put this short and sweet: If there were no bacteria in your digestive tract, you wouldn't be able to digest much anything.
