<p style=";text-align:left;direction:ltr">Weather of Arabia - The human body has enormous complexities, each cell in it has unique characteristics and performs specific functions. When we explore information about the human body, we always discover new things that we may not have known before. Here are some of these amazing facts mentioned on Boldsky and Brightside.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Our brains can turn on lamps</strong></h3><p style=";text-align:left;direction:ltr"> The human brain can generate enough electricity to light a small lamp, due to the presence of more than 160,000 kilometers of blood vessels in the human brain.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>You cannot smell while dreaming</strong></h3><p style=";text-align:left;direction:ltr"> According to experiments prepared to understand this matter, it has been shown that during the period of sleep known as “rapid eye movement”, which witnesses the occurrence of dreams, the person cannot smell anything in the outside world and is unable to distinguish smells due to his inability to use the sense of smell to interact with the world. Actual.</p><p style=";text-align:left;direction:ltr"> However, when consciousness is partially regained and something is smelled, it can cause the person to wake up if they enjoy the smell, such as waking up when smelling coffee.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Human teeth are similar to shark teeth</strong></h3><p style=";text-align:left;direction:ltr"> Human teeth are as strong as shark teeth. Despite the difference in structures and functions between the jaws of humans and sharks, the strength of their teeth is close. This is demonstrated in the ability of human teeth to bite and grind a variety of foods.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Your strongest and most emotional memories may be fake</strong></h3><p style=";text-align:left;direction:ltr"> Our strongest, most emotional memories often include some false aspects. While we might imagine that our memory works like a tiny camera that meticulously captures the details of every event, the frustrating truth is that it&#39;s more of a jumble. We put pieces together as we see fit, and may add decorative touches or even details that are not explicitly correct.</p><p style=";text-align:left;direction:ltr"> People often see things imperfectly, which means we may notice things that aren&#39;t there and overlook details that could easily be noticed.</p><p style=";text-align:left;direction:ltr"> Often times, people make wrong assumptions because they did not analyze the information properly to begin with. For example, a person may witness an event without having all the facts, and since he is unable to observe every detail, it becomes difficult or even impossible for him to see exactly what happened, causing his mind to create impressions to fill in the gaps that may not have actually happened. .</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Stomach acid can dissolve a razor blade</strong></h3><p style=";text-align:left;direction:ltr"> The acid in the stomach is so powerful, it can even melt a razor blade. The reason for the strength of this acid is due to its role in protecting us from harmful bacteria that may infiltrate our body through food.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Your left and right lungs are different from each other</strong></h3><p style=";text-align:left;direction:ltr"> The left lung consists of two lobes, while the right lung consists of three lobes, and the left lung is slightly smaller to make room for the heart. Each lung contains more than 300 million alveoli and more than 1,500 miles of bronchial tubes.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>The human face contains 70,000 expressions</strong></h3><p style=";text-align:left;direction:ltr"> Yes, the human face can show many facial expressions, estimated at tens of thousands, up to about 70 thousand expressions. This is based on the variety of muscles in the face and their ability to move in different ways, allowing the face to express a wide range of emotions and moods.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>The eye is the fastest muscle in your body</strong></h3><p style=";text-align:left;direction:ltr"> The eye is characterized by its ability to move quickly in all directions, making it the fastest organ in the body. The eye gets information even faster than other muscles, which can prompt it to move. For example, a person may quickly raise his hands to block an approaching object.</p><p style=";text-align:left;direction:ltr"> Nerves outside the eye control its movement, and the eye reacts in other ways as well, but this control is the most effective, as it controls the opening and closing of the iris through contractions inside the eye, allowing light to enter the pupil and perform other functions. Although there are other responses, they are slower than the responses of the moving bone of the eye. Healthy eyes should also blink regularly to maintain lubrication and remove dust and impurities, and the average number of blinks per minute is 15-20.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Your children have more bones than you</strong></h3><p style=";text-align:left;direction:ltr"> Our children carry more bones than adults, with about 60 extra bones. But, have you ever wondered where those extra bones go? The answer is simple: Babies are born with extra cartilage (connective tissue) compared to bones, and over time, this cartilage gradually turns into bone as they grow.</p><p style=";text-align:left;direction:ltr"></p><hr /><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Sources:</p><p style=";text-align:left;direction:ltr"> <a href="https://www.alarabiya.net/medicine-and-health/2017/10/12/5-%D8%AD%D9%82%... style=";text-align:left;direction:ltr"> <a href="https://www.aljazeera.net/health/2022/6/23/%D8%AD%D9%82%D8%A7%D8%A6%D9%8...
