The blood is pumped from the heart and circulates through the arteries and veins of the body. The blood brings oxygen and nutrients to every cell. It also transports wastes away from these cells.
Blood also helps keep regulate body temperature by carrying unwanted heat from the body parts to the skin.
Specifically, blood is composed of cells and plasma. These cells consist of platelets, red blood cells, and white blood cells.
While red blood cells transport oxygen from the lungs, white blood cells fight diseases and other infections. On the other hand, the platelets sole responsibility is to form clots in order stop bleeding when the arteries or veins are cut.
However, not all blood clots are good. If they were to form in blood arteries that takes blood to the brain, the blood clots can cause stroke. The same applies to blood clots in vessels leading to the heart – they can cause a heart attack.
All the above components float a liquid called plasma, which is mainly composed of water. Plasma also contains other elements such as nutrients, hormones protein antibodies, and electrolytes.
Indeed, people living in high altitudes tend to have more blood than their counterparts in lower altitudes. This is because of the air, wherein people living in higher altitude breath air with less oxygen. Therefore, it requires extra blood to deliver oxygen to the lungs.
Below let us know how many pints of blood in the human body are present.
How Much Blood is in the Human Body
Generally, men have more blood than women because of their size and weight.
An average man weighing between 70-80 kilograms will carry about 8 – 10 pints of blood. While women of average body build of between 60 – 70 kilograms would have about 6 – 7 pints of blood.
An average child weighing about 18-20 kilograms will have roughly half the amount of blood as a grown up.
In a nutshell, below are some few facts about the amount of blood in human body:
1. The amount of blood in a human body depends on age, sex, overall health and even where people reside.
2. Blood makes up roughly 7 percent of the weight of a human body.
3. Water makes up 90 per cent of blood plasma. Blood plasma also contains various electrolytes, glucose, gases, nutrients, proteins, and hormones.
4. An average adult male weighing 70 kilograms has a blood volume of a little more than 5 quarts, or about 5 liters.
5. The human heart pumps the body’s supply of blood of about 4.7 liters.
6. In just a single day, human blood travels approximately 12,000 miles.
7. The human heart beats around 35 million times every year.
8. The human heart pumps about slightly a million barrels of blood during the average lifetime. This amount of blood can fill three supertankers comfortably.
9. In essence, blood transports oxygen that comes from the air that the human breath into the lungs and to various body tissues by means of a network of arteries.
10. Humans living at high altitudes have up to two more liters of blood compared to their counterparts living at lower altitudes.
