What is the function of the cecum and appendix?
Appendix is connected to the cecum. Cecum provides a space for chyme to mix with bacteria for further digestion. Appendix is important in maintaining gut microflora and in mucosal immune response. Cecum is not involved with immune functions.
What is the structure of the appendix?
appendix, formally vermiform appendix, in anatomy, a vestigial hollow tube that is closed at one end and is attached at the other end to the cecum, a pouchlike beginning of the large intestine into which the small intestine empties its contents.

Or it may happen when the tube that joins your large intestine and appendix is blocked or trapped by stool. Sometimes tumors can cause appendicitis. The appendix then becomes sore and swollen.
Why is appendix vestigial?
The human appendix may be considered as a vestigial organ as it has been proved that the removal of the organ after infancy does not create any harm [1-3].
Why is the cecum important?

Why do we have an appendix grass?
The appendix has no known function in humans. Evidence suggests that our evolutionary ancestors used their appendixes to digest tough food like tree bark, but we don’t use ours in digestion now. Some scientists believe that the appendix will disappear from the human body.
What is the function of the appendix?
Appendix may have important function, new research suggests. The human appendix, a narrow pouch that projects off the cecum in the digestive system, has a notorious reputation for its tendency to become inflamed (appendicitis), often resulting in surgical removal. Although it is widely viewed as a vestigial organ with little known function,…
How does the appendix function as a replacement for the ureter?
In addition, the appendix has been successfully fashioned into a makeshift replacement for a diseased ureter, allowing urine to flow from the kidneys to the bladder. As a result, the appendix, once regarded as a nonfunctional tissue,…
What is the vermiform appendix?
The vermiform appendix or the appendix is a pouch-like structure that can be found attached to the large intestine. The large intestine, as we all know, is the portion of the digestive system where the small intestine ends and empties all its content for final absorption and excretion.
What is the size of the appendix?
In particular, it may serve as a reservoir for beneficial gut bacteria . The human appendix averages 9 cm (3.5 in) in length but can range from 5 to 35 cm (2.0 to 13.8 in). The diameter of the appendix is 6 mm (0.24 in), and more than 6 mm (0.24 in) is considered a thickened or inflamed appendix.
