The longest appendix ever removed was 26 cm (10 in) long. [3] The appendix is usually located in the lower right quadrant of the abdomen, near the right hip bone. The base of the appendix is located 2 cm (0.79 in) beneath the ileocecal valve that separates the large intestine from the small
In a 2007 study researchers from Duke University said it helps store good microbes or bacteria that help us digest food. Other research gives the appendix credit for strengthening our bodies immunity.
Ileum, caecum and colon of rabbit, showing Appendix vermiformis on fully functional caecum The human vermiform appendix on the vestigial caecum. The appendix was once believed to be a vestige of a redundant organ that in ancestral species had digestive functions, much as it still does in extant species in which intestinal flora hydrolyze cellulose and similar indigestible plant materials.

The question does not include the timing of when anything came to exist. Some have suggested the possibility of an infinite regress, where, if an entity cannot come from nothing and this concept is mutually exclusive from something, there must have always been something that caused the previous effect, with this causal chain (either deterministic or probabilistic) extending infinitely back in ...
Hospital lengths of stay typically range from a few hours to a few days but can be a few weeks if complications occur. The recovery process may vary depending on the severity of the condition: if the appendix had ruptured or not before surgery. Appendix surgery recovery is generally much faster if the appendix does not rupture. [98]
Countries are expected to reach a deal at this month's U.N. COP16 nature summit on how the world uses and pays for genetic information extracted from nature, according to negotiators. Experts ...
In humans, the vermiform appendix is sometimes called a vestigial structure as it has lost much of its ancestral digestive function.. Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. [1]
The appendicular skeleton is the portion of the vertebrate endoskeleton consisting of the bones, cartilages and ligaments that support the paired appendages (fins, flippers or limbs).
