Organs which seem to be left over from an ancestor are called vestigial organs. Animals like rabbits have much larger appendices than we do. Bacteria which live there help to digest grasses. Perhaps some of our ancestors had a similar diet.

A body part which is reduced in size and seems to have no function is called what?

That body part is often referred to as a vestigial structure. These are remnants of organs or structures that had a function in the organism's evolutionary past, but have reduced in size or lost their function over time. Examples include the human appendix and tailbone.


A body part which is reduced in size and seems to have no function is called?

A body part that is reduced in size and seems to have no function is typically referred to as a vestigial organ or structure. These may be remnants of evolutionary adaptations that are no longer needed in current organisms. An example in humans is the appendix.


What is a structure that don't seem to have any function but may once function in an ancestor?

An appendix in humans is a structure that seems to have little function, but it may have been more important in our ancestors for digesting cellulose. Similarly, the tailbone (coccyx) in humans is a remnant of a tail that was functional in our primate ancestors for balance and mobility.


What is A body part which is reduced in size and seems to have no function is called?

Vestigial structures. Like the appendix in humans.


Is pendix a body part?

No, "pendix" is not a body part. It seems to be a misspelling or confusion with the term "appendix," which is a small, tube-like structure attached to the beginning of the large intestine.


Which is an example of a vestigial structure?

tailbone of a human whale pelvis bone


Cellular synthesis of steroids seems to be the function of this structure?

Why do people need an appendix?

You don't need appendix. It is a vestigial structure that only might get in your way if it becomes inflamed.However, recent research shows that it creates helpful bacteria.Researchers at Duke University Medical Center say that the function of the frequently discarded appendix, an organ often credited with little importance and often dismissed as having no significant function, does it all;the appendix produces and protects good germs for the gut by "rebooting" the digestive system.However the researchers say sometimes the bacteria die off or are purged from the intestines as in diseases such as cholera or dysentery. According to the researchers, the appendix's job is to "reboot" the digestive system when that happens with the bacteria safely harbored in the appendix.It was once believed that when the human passed gas it caused the appendix to twist and release bacteria ... but that rumor was dissmissedMany doctors believe the appendix is a vestigial organ with no function and is no more than a blind ended tube connected to the cecum, from which it develops embryologically.he cecum is a pouch-like structure of the colon and the appendix is near the junction of the small intestine and the large intestine and has abundant infection-fighting lymphoid cells, which suggests it plays a role in the immune system.The most common diseases of the appendix (in humans) are appendicitis and carcinoid tumors. Appendix cancer accounts for about 1 in 200 of all gastrointestinal malignancies.Appendicitis is a condition where the the appendix becomes inflamed and in almost all cases it is removed either by laparotomy or laparoscopy; left untreated, the appendix will rupture, leading to peritonitis, then shock, and, if continued untreated, death. The appendix is routinely removed without any notable ill effects or side effects and the scientists stress that even though the appendix seems to have a function, people should still have them removed when they are inflamed because since leaving it untreated could be fatal.Dr. Bill Parker, a professor of surgery and one of the scientists responsible for establishing its status as a useful organ, says the function of the appendix seems related to the massive amount of bacteria that populates the human digestive system and where it is located just below the normal one-way flow of food and germs in the large intestine, helps support that theory.The study appears in the online edition of the Journal of Theoretical Biology.


Name the small projection that contains lympathic tissue attached to cecum?

The small projection that contains lymphatic tissue attached to the cecum is known the appendix. The full name is actually vermiform appendix which is derived from its appearance which look like a worm.


Do you need your appendix?

The most obvious answer is no; millions of people have had their appendix removed without ill effects. Darwin suggested that the appendix is a leftover from when our ancestors used to digest leaves. Recently, it's been suggested that the appendix is used to keep bacteria that keep the colon in good order, however it doesn't seem to cause a problem to have it removed. Given that it's seems largely useless and a burst appendix used to be a fatal disorder, one might ask why it's survived at all. One theory is that a smaller appendix is more prone to bursting so it's reached a sort of happy medium value.


Where is your appindics?

The term "appindics" seems to be a misspelling or may not be widely recognized. If you meant "appendix," it refers to a small, tube-like structure attached to the large intestine, located in the lower right abdomen. If you were referring to something else, please clarify, and I’d be happy to help!


What is an analigus structure?

It seems like there might be a typo in your question. If you meant to ask about an "analogous structure," it refers to similar structures found in different species that have evolved independently to serve the same function. These structures are not inherited from a common ancestor but have similarities due to similar environmental pressures.
