Despite being an integral part of ourselves, our body still hides a multitude of secrets . That's why studies are conducted daily to better understand its functions and capabilities, and the findings never cease to surprise us.
Did you know that we are born with more bones of those we eventually have when we are adults? And that in our body flow more than four liters of Blood ? We'll share these and other surprising facts about our bodies.
Human bones
Humans are born with 300 bones, many of which are small or made of cartilage. As we grow, smaller bones join together, so the total number decreases. Those made of cartilage eventually become bone.
We have between 4 and 5 liters of blood
An average adult has between 4.5 and 5.5 liters of blood flowing through their body. Men tend to have slightly more than women. The figure also varies depending on the stage of life. A pregnant woman, for example, has approximately one to one and a half liters more blood than a non-pregnant woman.
We have about 1200 muscles
Humans have nearly 1,200 muscles in their bodies. More than half of them are located in the head and neck. While we activate some muscles at will, others, like the heart, function at the command of the autonomic nervous system.
39 trillion bacteria live inside us
Bacteria are an important part of our bodies. Many protect us from disease, while others help renew parts of our bodies. In total, we have a whopping 39 trillion of them.
We have 78 organs
Although the number of organs can vary depending on how they are counted, the figure most widely accepted by the scientific community is 78. Although some of them are repeated in the body, they are counted only once.
Our brain weighs on average 1.4 kilos
When we are born, our brain weighs about 350 grams, and it can gain weight to an average of 1.4 kilos by adulthood.
More than 80 billion neurons
A person has more than 80 billion neurons in the brain alone. This type of cell is also present in the spinal cord and digestive system.
Hair growth
Our hair grows an average of 15 centimeters per year, about 0.4–0.5 millimeters per day. We lose about 50–100 centimeters per day.
The strongest muscle is the gluteus maximus
The gluteus maximus, which supports the upper body, is our strongest muscle. It helps us stay upright and facilitates mobility.
More than 99% of our DNA is the same
Although we may think we are very different from one another, the truth is that human beings share more than 99% of our DNA.
We produce between 1 and 2 liters of saliva daily
A healthy person produces between 1 and 2 liters of saliva per day. The amount of saliva we produce varies depending on whether we're resting, eating, or drinking.
