How much blood does the human body contain?

Humans will not be able to survive if there is anemia in the body. This essential liquid in an adult's body is enough to fill a 1-gallon milk container.

Dr. Daniel Landau, a hematologist and oncologist at Orlando Cancer Center of the University of Florida (USA), said an average adult has about 4.5 to 5.5 liters of blood stored. clear inside their bodies.

Without blood, our body weight will drop by 8-10% and, of course, we will also die. This means that in a person who owns a 54kg weight, the blood in their body accounts for 4.4 - 5.4kg.

At 5-6 years of age, children have the same amount of blood as adults. However, because children are smaller with muscles, bones and viscera not as heavy, their blood accounts for a larger proportion of total body weight than in adults.

Meanwhile, babies don't have much blood in their bodies. A child is born with a weight of about 2.3 to 3.6kg with only about 0.2 liters of blood in the body. This is equivalent to the amount of blood in a cat weighing 4.5 kg, said Dr. Greg Nelson, a veterinarian in New York, USA. Dogs have a bit more blood in their bodies , meaning a dog weighing 36kg has 3 liters of blood.

An interesting little thing is, the amount of blood in the human body is different among individuals , depending on factors such as age, gender, overall health and even where to live. For example, men tend to have greater blood volume than women who own the same body size and weight.

People living in the uplands also have the ability to own up to 2 liters more blood than those who live in lower places. Experts explain, this is because, the air above is much less oxygen, so people living there need more blood to transport enough oxygen to the lungs.

When an adult donates blood, health workers often draw 500ml of their blood.

Blood cells have a lifespan of about 120 days and the body continuously produces new blood cells in the bone marrow. However, bone marrow still needs time to regenerate blood cells, so this is why we cannot donate blood too often.

In adults, blood in the body contains about 3 liters of plasma, red blood cells, white blood cells and platelets. Vitamins, electrolytes and other nutrients are dissolved in the blood and transported to cells and organs.

Human blood also contains gold and this metal accounts for about 0.02% of the total blood volume in the body. This is equivalent, you need blood of about 40,000 people to exploit about 28g of gold, too little and not enough to make anyone rich.

Meanwhile, iron exists in much larger quantities in human blood . This element helps blood cells maintain a round shape, which helps explain why adults have about 3 - 4g of iron floating in their blood.
