Does the appendix play an important role in human digestion?
No, but it protects the stomach from digesting things.
Since "vestigial" means an organ that is atrophied or functionless from the process of evolution, out of the list of four structures that are given, the human appendix is that vestigial organ. All of the other organs, especially the "multiple cow stomachs" and the horns of a deer do play an important role to that animal's life.
As of yet, the purpose of the appendix in the human body is not known. It is simply there and is often removed. Anyhow, appendix do play role in fetal development and adult.In fetus appendix act as a endocrine organ and in adult they help our body immune system to combat against microbes as it 'train' our immune system by exposing antigens to lymphoid cells in order to produce antibody.
It doesn't have a job in the human body, the fact that it is very large in grass eating animals suggests that it used to play a part in the digestion of cellulose (something we can't now digest which is why eating grass is not recommended!). We have evolved to not need it, which is why it is so small in humans compared to other omnivores. As an aside, I've always suspected that it is…
Certain evolution-minded people think that it is the remnant of an organ that allowed our ancestors to digest cellulose, enabling them to eat greenery. However, there are several opposing schools of thought regarding this. Recent findings indicate that the appendix is not actually as useless as has been previously thought, and may play an important role in various physiological functions such as the human immune system. Long ago when food was dirty, the appendix separated…
No way. It interferes. More Information Actually, that depends on what is served for dessert. Heavy, fat-filled cakes and pastries probably won't help much, but fruit like mangoes, papaya and pineapple will help the digestion process. Spices apparently have an important part to play, too.

The parasympathetic division of the autonomic nervous system stimulates digestion. It activates salivation, which functions in digestion as the beginning of breaking the food down. It also stimulates the gall bladder to release bile for digestion. Digestion in the small intestine is increased and gastric juice in the stomach is secreted.
