The jejunum pretty much is just a tube in which chemical digestion occurs and nutrients are absorbed.
3.
Earthworms accelerate nutrient cycling in the soil-plant system through fragmentation & mixing of plant debris physical grinding & chemical digestion.
4.
The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine, where most chemical digestion takes place.
5.
These products of chemical digestion pass through the epithelial lining of the gut into the blood, in a process known as absorption.
6.
The mistletoebird has a small muscularized stomach and short alimentary canal where the amount of mechanical grinding and chemical digestion is minimized.
7.
The large intestine produces no digestive enzymes chemical digestion is completed in the small intestine before the chyme reaches the large intestine.
8.
Chemical digestion involves hydrolysis reactions that liberate the sub unit molecules primarily monosaccharides, amino acids and fatty acids from the food.
9.
Mechanical and chemical digestion begin in the mouth where food is Absorption occurs in the stomach and gastrointestinal tract, and the process finishes with defecation.
10.
:Very little bacteria survives the beginning of chemical digestion in the stomach & mdash; the low pH ( high acidity ) pretty effectively kills most bugs.
