Few Amazing Facts About Human Blood That You Were Not Aware Of

On an average day, you probably don’t spend a lot of time thinking about human blood. But we’d like to see you try to live without it! Except not actually – we like you the way you are, i.e. alive. The more you know about blood, though, the more you will come to respect it. When it’s not busy feeding vampires, your blood is taking care of more aspects of your health than you might expect. And all it asks in return is that you not get stabbed too often.

Let’s See Few Incredible Facts About Human Blood:

1. Human Body Takes Two Months To Produce 1 Pint Of Blood

After you lose a pint of blood, ideally through donation, but also through any sort of bloody injury, your body gets to work replacing it. Within a single 24-hour period, your body can draw in enough fluid and nutrients to replace the fluid plasma lost, but it can take up to eight weeks for your bone marrow to reproduce all the red and white cells lost in that precious pint.

2. There Are Five Million Red Blood cells In a Cubic Millimeter Of Blood

Your red blood cells which are properly termed “erythrocytes,” by the way are numerous, to say the least. In fact, there are more than 5 million of them in the average cubic millimeter! And that’s a good thing because an average of 2 million red blood cells dies each and every second.

3. Human Heart Pumps Out Around 6 Quarts Of Blood In Each Minute

That’s a gallon and a half of blood every minute! So if you were paying attention to our first fact, then you got it: That means almost every single drop of your blood makes a round trip every minute of the day. Of course, this is again an average, as the blood that has to go to your toe tips takes longer to return than the stuff that goes to your lungs or head, but still, pretty good work, the human heart.

4. There Is a More Blood Than You Might Think

The average human being is walking around with more than 5 liters of blood in them. Of course, there is a huge range between, say, a 5-foot-1 woman who weighs 90 pounds and a 6-foot-6 man who weighs 280, but we said average, that’s humongous. To break that down for you, 5 liters equals 1.3 gallons or just more than 20 cups. That’s a lot of 8-ounce servings of blood, isn’t it?

5. Blood Consists of Four Components

Blood is mostly plasma, which is a yellowish fluid that carries along the three cells that get the job done. Red blood cells, by far the most numerous, deliver oxygen to every part of your body. White blood cells battle bacteria and viruses. Platelets help your blood to clot and form scabs, sealing wounds. But beyond those basic components, at any given time your blood is also carrying sugar, calcium, alcohol, cholesterol, vitamin B-12 and just about anything else you put into your body.
