  1. Adults

  • The weight of an average adult lies between 150 to 180 pounds.

  1. Pregnant women

  • The amount of blood in the body of a pregnant woman will be significantly higher when compared to the others. This excess blood helps them to support the growth and development of their babies.

Find out how much blood you can donate or lose..

If you are wondering how much blood in human body, then you might also be curious to find out the volume of blood that you can donate or lose. Blood donation is indeed a very noble deed, and it is always encouraged. But, there are a number of points that should be kept in mind if you are intending to donate blood. The first and foremost criteria is the amount of blood that you can donate. 

  • According to different health organizations, the standard amount of blood that a person can donate is about 1 pint. This is regarded as a very safe amount, and it accounts to about 10% of the total blood that is present in our body.

  • It should be kept in mind that after donating the blood, you might experience some dizziness. Some even tend to faint after donating blood, and this is completely normal, and there is nothing to worry about.

  • Because of this dizziness, the donation centers will usually ask the people to rest for 10 to15 minutes. The officials at the centers will also insist that they take some refreshments before leaving the donation center.

  • However, it should be noted that if a person has an accident or illness, then he or she might lose more blood. Such situations are indeed very serious, and it might lead to shock which can be life threatening.

  • When a person loses blood, the body will begin to take the blood towards the vital organs of the body. As a result, the blood flow will be directed away from the skin, fingers, as well as toes.

Maintenance of blood levels in the body

Now that we know how much blood in human body, let’s take a look at the mechanism by which our body maintains the blood levels. 

  • As we all know, the cardiovascular or circulatory system is responsible for the transportation of the blood across the body. The heart helps in pumping the blood to the different blood vessels.

  • Thereafter, these blood vessels assist in delivering blood to the different organs of the body. Through the blood, oxygen and different essential nutrients reach each and every part of our body.

  • In addition to the cardiovascular system, there are a number of other organs and systems that play a very important role in maintaining the blood volume. These include the kidneys, skeletal system, and nervous system.

  • The kidneys help in regulating the fluid balance of our body. Bone marrow, which is a very important component of the skeletal system, helps in producing blood cells. Lastly,  the nervous system helps all the other systems to accomplish their tasks successfully.
