Facts About Blood

Everybody knows that when you cut yourself, you’re going to bleed. This is due to the continuous movement of blood throughout our bodies. But do you know all the functions of this circulating system? No? Now we’ll tell you some facts about blood that you certainly didn’t know.

What not many people know is that doctors still use cutting people as a cure for patients of a disease. For over two hundred years, this has been one of the most common ways of curing people. Doctors used to believe that the body’s natural balance could be restored by removing the excess blood present in the body. 

In some cases, leeches are also used to cure people of a disease. The substance released by leeches also has other positive side effects for the body, comparable to antibiotics.

In addition, all the blood in our body is responsible for about 8% of our weight. An adult body has about 5 liters of blood in it. An exception to this are pregnant women. They can produce up to 50% more blood because they also have to supply the unborn child with blood. 

The blood in our body consists mainly of red blood cells. The red blood cells are indirectly responsible for the transport of oxygen to other parts of the body. In addition, their carbon dioxide is transported back from other cells to the lungs. These blood cells last about 120 days.

This is due to a significant increase in heart rate and blood pressure. Part of the body has the human thought of ‘fleeing or fighting’. After the sudden rise, there is also an acute drop in the above factors. In some cases, the body goes too far in this, which can cause people to faint.
