Humans have become curious about what is in their bodies thousands of years ago. The ancient Egyptians processed all human organs when they mummified. The job is basically to remove all organs and organs most likely to rot from the dead body and destroy or put them in a separate jar.
The earliest human medical anatomy manuscripts have been found in China. They describe a rather complex understanding of medical practitioners who lived 2,200 years ago. But now, with general knowledge, can you defeat the ancient people in understanding your body or not?
There’s a question to help you test that out. Guess how many organs there are in total?
Lisa M.J. Lee, an associate professor at the Department of Cell Biology & Development, University of Colorado Medical, defines: “An organ is a collection of tissues working together for a common purpose. Accordingly, every organ provides a function either dynamically or for human existence. ”
But not any organs are necessary for your survival. If that’s all, then you only need the following five organs: brain, heart, liver, one kidney and one lung. They are called vital organs of the body, and only one of these organs loses function, leading to death.
In addition, the human body can exist without the need for many other internal organs. Or you can replace them with a medical device that serves the same function.
To answer the question “How many organs are there in the human body?“It depends on who the questioner is and how you count it,” said assistant professor Lee.
The most common number, the body has all 78 internal organs. This list includes vital organs such as: tongue, stomach, thyroid, urethra, pancreas, plus many single organs or pairs of other organs. Bones and teeth are counted only once.
But anatomists themselves are arguing over differing views on the definition of an organ. Histologists including associate professor Lee (those who study tissue at the microscopic level) are able to count more parts of the body as internal than general anatomists (those who study organs can only be seen with the naked eye).
In 2017, for example, scientists proposed to call the mesenterus – the part that attaches the intestines to the abdominal wall an organ. The process of manipulating the mesenteric list has taken a lot of time and effort by new histologists to convince the anatomic world.
But it is not always possible for both to agree. Based on Lee’s micro-definition, as long as some body tissue is gathered together to accomplish the same goal, it is called an organ.
In this way, we can call the nail or root of the tooth a separate organ. “I would consider each bone to be an organ, and all of the 206 bones together, are considered one organ system. “, said assistant professor Lee.
But since bones are only listed once on the list of 78 internal organs, in order to get the total number of organs under this definition, 205 must be added and the number is now 284 in total.
Counting each tooth individually pushes the list to 315 organs. Many other organs are only listed once, although there are many of them throughout the body. For example, ligaments and tendons can significantly increase the total number of organs when counted individually.
This numbering game could eventually lead to a huge number. The list of 78 organs has removed all repeating organs, otherwise we could have trillions of organs by histological definition.
It is also for this reason that assistant professor Lee often tells his medical and graduate students to accept a vague number. 78 is a number that we can say to each other.
In addition, once you know how many internal organs you have in your body, you can make a checklist to take care of them. Like a car with many components, you need to pay attention to how to maintain and maintain your body regularly.
Take a simple example: Brushing your teeth every day means you are doing maintenance on your 32 teeth. Exercise means you are maintaining the skeletal system and muscles. Limit your intake of fats and oils, you are protecting your heart and blood vessel system. The same is true of a low-sugar diet, quitting smoking and alcohol …
“Increasingly, I feel the importance of the things you put into your body to feed your cells, tissues and organs “, said assistant professor Lee. So, keep a healthy lifestyle so that you can protect your whole body.
