Medical Video: Why Can't Humans Regrow Body Parts?
The human body has been designed in such a way with various amazing abilities. One of the abilities possessed by the human body is to regenerate (renewal) the liver. The human liver, which is also called the liver, can indeed grow again if there is damage or if you donate some of your liver to other people. Simply put, this update process is similar to the tail of a lizard that will grow again if it breaks.
How can the human heart grow again? See the full explanation below, yes.
How can the human heart grow again if there is damage?
Some studies have even proven that your liver can grow again even though there are only 25 percent of the remaining organs that are still functioning.
The regeneration process can occur because hepatocytes, the main cells that make up the liver, can reproduce themselves. Hepatocytes work like stem cells (stem cells) in the sense that hepatocytes can multiply. After the hepatocytes multiply, other cells will also follow and break up into different cells. The new cells then form a new structure, resembling the original human liver.
Although it can grow again, a liver that has undergone regeneration (repair or renewal) will not be exactly the same as before. The size can be the same, but the shape may be different. His ability to carry out metabolic functions may also not be as powerful as your original organ. This all depends on how strong the multiplication and breakdown of cells that occur during the regeneration process. Because the hepatocyte cells are not as sophisticated as stem cells.
Can other human organs grow again like the liver?
Only the human heart has so far been able to regenerate or grow back. Other parts of your body, such as bones and skin, can indeed improve. However, hepatocyte cells can only regenerate into hepatocyte cells, not other cells that may be needed.
This is because the human heart is an organ whose task is to collect and dispose of poisons in the body. These organs are the most vulnerable to damage. If the liver stops functioning, humans can die in an instant. So, the human heart has a special system to regenerate if there are tissues or parts that are destroyed.
While humans can still survive without certain body parts, such as legs or arms. So instead of wasting too much energy to regenerate less vital parts of the body, the human body is more concerned with regenerating vital organs.
The lizard tail itself can grow again in a short time because the size and system of lizard body tissue is not as large and as complex as humans. So, the energy needed to grow the tail after breaking up is not too big.
Then why are there still liver diseases that attack humans?
Unfortunately, hepatocyte cells that make up your liver have limitations. If the damage to the liver is too excessive, hepatocytes cannot regenerate.
In addition, if the damage is severe enough, the scar tissue will grow to cover the liver. This scar tissue eventually replaces damaged tissue, not new tissue formed from hepatocyte cells. This is why you can still get cirrhosis until liver function failure.
So the best way to maintain the health of the human heart is to stop smoking, limit consumption of alcoholic beverages, avoid foods that have been contaminated with pesticides and other harmful chemicals, and live a healthy lifestyle.
