The function of the appendix is unknown. One theory is that the appendix acts as a storehouse for good bacteria, “rebooting” the digestive system after diarrheal illnesses. Other experts believe the appendix is just a useless remnant from our evolutionary past.

Some studies suggest that as ancient humans were predominantly herbivorous, they used their appendixes for digestion. However, as humans evolved, they started to include more easily digestible food in their diet and the appendix eventually lost it function.
Was the appendix used for digesting raw meat?
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.
Was the appendix ever useful?
The appendix, notorious for its tendency to become inflamed or even rupture, has historically been viewed as a vestigial organ with no real function. But new research supports the idea that the appendix may indeed serve a purpose: to protect beneficial bacteria living in the gut.

What did the appendix evolve from?
Darwin theorized that the appendix in humans and other primates was the evolutionary remains of a larger structure, called a cecum, which was used by now- extinct ancestors for digesting food.
Can you regrow an appendix?

Does removing appendix affect anything?
For most individuals there are no long-term consequences of removing the appendix. However, some individuals may have an increased risk of developing an incisional hernia, stump appendicitis (infections due to a retained portion of the appendix), and bowel obstruction.
What organs do humans not need?

- Spleen. This organ sits on the left side of the abdomen, towards the back under the ribs.
- Stomach.
- Reproductive organs.
- Colon.

Do humans have 2 appendix?

What organs can burst?
Appendicitis is swelling (or inflammation) of the appendix, a narrow, tube-shaped organ attached to the large intestine on the lower right side of the abdomen. The condition may cause the appendix to rupture, a complication that can be life-threatening.
How painful is an appendicitis?
Appendicitis usually involves a gradual onset of dull, cramping, or aching pain throughout the abdomen. As the appendix becomes more swollen and inflamed, it will irritate the lining of the abdominal wall, known as the peritoneum. This causes localized, sharp pain in the right lower part of the abdomen.

- Appendix.
- Kidney.
- Gallbladder.
- Liver, sort of.

What causes appendicitis in a child?
