It is being said that our body is among the most complicated mechanisms present in this world. However, this complex mechanism is home to some other mechanisms which make the functioning of the body possible. But have you ever noticed that our body behaves in an unexpected manner sometimes?
This is because it also has some flaws in its designing which gives rise to surprising and strange behavior. We have to admit the fact that our human body is not perfect as Alan Mann who is a physical anthropologist by profession once said that evolution produces function and not perfection.
Here are 15 basic design flaws of our human body:
We all must have bitten ourselves inside our mouth at some point of time and this is definitely one of the worst experiences that anyone can have. It is painful, takes time in healing and causes irritation because of certain food items. We can neither apply any lotion or cream on the wound nor use a bandage. It happens when a person’s attention gets diverted while chewing food and this is the time we feel the lack of coverage to protect our inner cheeks.

We have heard many times that a person got his appendix removed by an operation as it was paining but have you ever thought what does appendix do inside our body? The function of appendix is unknown but a person can live without it easily. So the question that arises here is whether the appendix is present in our body just to get infected?

The purpose of eyelashes is to protect our eyes from dust and sand particles as they can cause irritation if they enter our eyes. However, when an eyelash breaks down, it goes into our eyes and causes irritation, defeating its own purpose. The design of our eyelids can be called flawed for one more reason and that is we have only one set of eyelashes while most of the animals have two sets.

Pain in tooth can be unbearable at times and a person is not able to eat, talk or sleep without taking medication or undergoing dental procedure. The tooth problem may be very painful but one thing is for sure that it is not a life-taking disease. However most of the times, people get to know that they are suffering from a serious disease after several years as they never felt any pain due to it.

Each foot of ours has 26 bones which mean that one-fourth of the total bones of our body are in our feet. We may face injuries in our feet because of this, such as broken ankles or sprains. However, these many bones were useful when our ape-like ancestors used to jump from one branch to another using the feet. This design is of no use now as we walk upright.

Well, we are making this statement because almost 80 percent of humans suffer from neck pain or back pain. Earlier our ancestors used to walk on all fours; at that time the spine was in the shape of an arc and it was perfectly shaped for carrying the weight of all the organs. However, after the evolution, a lot of changes came in spine because of which 80 percent of the adults are suffering from back pain.

Because of the evolution, the female pelvis has two problems. As the humans walk on two legs, it has tilted the birth canal and the child has to take a sharp curve at the pelvis while taking birth rather than coming out through a cylindrical canal. This is why human births are more complicated than other mammals.
One more reason to worry is the size of human’s head. Thanks to evolution, we have big brains because of which the size of head is also bigger. The baby’s big head can cause problem while birth as the size of pelvis is already small.

Mostly all the men have hair on the whole body but we tend to lose hair only from our head. This not only spoils the look but can also lower the confidence of a person. Even though there are many hair treatments available, still the hair on the head should be extra strong naturally.

Our lives can go pretty smoothly without a wisdom tooth too but they have to come out crooked, give us pain and spoil the complete jaw structure. They make us feel uncomfortable as we always feel something is sticking in our mouth and when it becomes unbearable, we spend money to get it out.

Most of the vertebrae species have the capacity to produce Vitamin C but we humans can’t do that and for Vitamin C we have to drink juices such as orange juice. One point which needs to be mentioned here is that if we don’t have enough Vitamin C in our body, we may suffer from scurvy.
One interesting fact about the human body is that we have a gene to synthesize Vitamin C but due to the changes that came in our body after evolution, that gene was made ineffective.

We have a blind spot in both the eyes and this happens because the humans have an inside-out retina. The blind spot is a small area of visual field which is parallel to the position of optic disk. The optic disk has no photoreceptors because of which no image is seen. However, in the case of animals like octopus and squids, they don’t have blind spots.

When a person eats his meal, the food goes to stomach through food pipe (esophagus) and epiglottis (flap of tissue) covers the trachea (windpipe) but when epiglottis gets diverted and food goes into trachea, the person gets choked.
However, when we talk about human babies and other mammals, the epiglottis is all the way up in the back of their mouth. They can eat and breathe at the same time as their larynx (voice box) is also the way up, and this is something which adult humans can’t do.

Allergies can be said to be a reaction of the body when it comes in contact with a foreign substance; for example, pollen, pet dander, etc. However, what is surprising is that these substances are not harmful to everyone and only those who don’t have the required antibodies suffer with allergic reactions.

Humans sweat to maintain the body temperature which is a common feature among the mammals. However, the number of sweat glands is too high in humans in comparison to other mammals and because of this, humans are the least efficient thermoregulators. In fact, they tend to lose a large quantity of water just by walking or exercising.

When blood thickens and forms clumps, a tiny blood clot is formed which is called “deep vein thrombosis” (DVT). Most of the time, they occur in thighs or lower legs. When a clot gets separated from a vein, it will go into the bloodstream and when it reaches lungs, blood flow is blocked. Due to this, a serious condition called “pulmonary embolism” is emerged. This can damage lungs and even take a person’s life in the worst case scenario.
