The blood in our body is very important that even a liter of blood lost can kill us. Just like how gasoline helps make a machine or an engine work, the blood supplies nutrients and oxygen to our cells to keep us alive. Without blood, we will surely die. This is the reason why a simple blood loss can actually be serious. If you’ve seen vampire movies, then you’ll surely understand how important the blood is.

Here are some facts about the blood that can help you further understand what the blood does to our body.

According to studies, almost 4.5 million Americans need blood transfusions in a year.

Someone needs blood every two seconds, or 30 people in a minute.

1 out of 7 people admitted in a hospital need blood.

A pint of blood can help save three people’s lives.

There are four main red blood cell types: A, B, O and AB. AB is the universal recipient while O is the       universal donor.

The major human blood groups were first identified in 1901 by Dr. Karl Landsteiner.

There are several components in one unit of blood, such as the red blood cells, plasma, platelets and cryoprecipitate.

Platelets promote blood clotting. It also helps those with leukemia and other types of cancer.

Red blood cells can last up to 120 days in the circulatory system.

Plasma is a mixture of salts, water and protein, and it has a pale yellow color.

55% of blood volume is made out of plasma.

Red blood cells, plasma and platelets are made by healthy bone marrow.

Blood or plasma that is paid for cannot be used in human transfusion.

White blood cells are the body’s primary defense against inspection.

Granulocytes, a type of white blood cell, search for bacteria to destroy by rolling along the walls of the blood vessels.

Apheresis is a special kind of blood donation wherein the donor can donate specific blood components.

Donated red blood cells can only be stored for forty-two days, while donated platelets can be stored for _  five days.  Frozen plasma, on the other hand, can be stored for a year.

Before donated blood can be used, it has to undergo thirteen tests, eleven of which are done to check for      infectious diseases.

A newborn baby has about one cup of blood, while an adult has about ten pints of blood.

Just by reading these facts, you’ll realize how important blood is. If you are a healthy adult, without any illnesses or anemia, you can easily help save other people’s lives by donating blood. It only takes 2 months for the minerals and iron from your blood to be replenished after a donation, so you can actually donate twice or thrice a year. Research shows that those who donate blood regularly have healthier blood, since the red blood cells and other components of the blood can have enough time to get replenished.

If you want to be able to help save lives while earning a living at the same time, why not try and train to become a phlebotomist? It only takes four to eighteen months before you can get your license. It is a quick and easier way to enter the world of medicine. If you like what you’re doing, you can even continue studying to become a nurse or a doctor. There are a lot of people who need to have their blood tested, and as a phlebotomist, it is your job to help them.
