Humans have several vestigial body parts, remnants from ancestors, like the tailbone (coccyx), wisdom teeth, and ear muscles, that have reduced or lost their original function, though some may have minor secondary roles or potential immune functions, while other debated parts like the appendix are now thought to aid gut health or immunity.
Some human body parts have become useless over the past few million years. These include wisdom teeth, the tail bone, and the muscle fibers that produce goose bumps.
What Organs Can You Live Without?
In humans, the vermiform appendix is sometimes called a vestigial structure as it has lost much of its ancestral digestive function.
The brain is arguably the most important organ in the human body.
According to the theories of Charles Darwin, the appendix was a vestigial structure, useless and devoid of function. It might even be seen as potentially dangerous to health due to the risk of inflammation of the organ.
Seven (mostly) unnecessary body parts
You'll be surprised as to how much you could lose and still live. You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs.
Z: The Zygomatic Bone
The facial skeleton contains the zygomatic bone, also referred to as cheekbones. It constructs eyeball housing and provides facial tissues with support.
The coccyx functions as a site of attachment for muscles and ligaments of the pelvic floor, to support the position of the anus, and to provide weight-bearing support to a person in a seated position. Injury or damage to the tailbone area may result in coccydynia.
Even when vascular collapse is the primary event, brain and lung functions stops next. The heart is the last organ to fail. The heart stops following PEA, but PEA is not cardiac arrest. The heart finally stops when it arrives at asystole, which is cardiac arrest (Figure 1).

The Rarest Body Features, According To Science
Appendix. 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.
In the realm of positive psychology, the answer to whether everyone has a purpose is answered with a resounding “yes.” The pursuit and realisation of purpose align with fundamental human needs for meaning, fulfilment, and resilience.
Following this evolutionary split, the group of apes that includes present-day humans evolved the formation of fewer tail vertebrae, giving rise to the coccyx, or tailbone. Although the reason for tail loss is uncertain, some experts propose that it may have better suited life on the ground than in the trees.
In human anatomy and physiology, there are no standard body parts that start with the letter "q." However, for the purpose of this exercise, let's consider the term "quadriceps femoris" as a relevant term that starts with "q" and is significant in human anatomy.
Human Weak Points for Self-Defence
The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system.
Therefore, ears and the nose is the most reliable and observable answer to the question of which parts of the human body never stop growing.
To the 78 organs that make up the human body, a group of scientists says we should add one more: the mesentery. Located in our abdominal cavity, the mesentery is a belt of tissue that holds our intestines in place.
Your liver is the largest internal organ in your body and one of the only organs that can regenerate itself. The liver plays a crucial role in filtering blood, storing energy and producing bile for digestion.
If not now, the appendix had an important role to play, several millions of years ago. As per Charles Darwin, it helped humans digest plants. As our diet has also changed over the centuries, the appendix is practically useless.
In a remarkable anatomical discovery, scientists have identified a previously unknown pair of salivary glands hidden deep behind the nose—marking the first addition to major human salivary glands in centuries.
Functions of the Clavicle in the Human Body
Despite being the weakest bone, the clavicle performs several important functions that are crucial for upper body movement and stability. Support and Stabilization: The clavicle plays a key role in supporting the shoulder and maintaining its alignment with the body.
