Forget about young blood! Your body is constantly making new blood every second of your life and this process is unlike anything else around.

Our bodies are pretty incredible, so far weve covered what blood is made of, what the different blood types are, and in this Human episode we are exploring how our bodies actually make more blood.

The creation, maintenance, and filtration of blood is a unique process thats different from our other cells. Luckily, weve got some organs and physiology up for the task.

So unlike when our body wants to create new skin cells or stomach cells using mitosis, creating new blood cells requires a bit more work. Red blood cells cant make direct copies of themselves because they ditch their nuclei as they mature. So your body has to constantly manufacture and eject blood in order to keep the correct number of cells in circulation so you can continue to, well, function.

And this whole process starts in the bone marrow and utilizes a number of different organs along the way including the liver and spleen.

Find out more about how our body continues to produce new blood in this Human.

Searching in vein: a history of artificial blood
For centuries scientists have sought an artificial substitute for blood. Equipped with modern nanotechnology and a humbler strategy, bioengineers think theyre closer than ever.

How Did Red Blood Cells Evolve?
Ill-conceived blood transfusions go back to the 1600s (disastrous transfusions of lambs blood into humans), and the discovery of the ABO system goes back to the early 1900s. But just how old is blood itself? A picture from the Smithsonian in 2009 showed a red blood cell (RBC) in the soft tissue of a Tyrannosaurus Rex bone from 68 million years ago. But blood cells go back, really far back.

This Seeker health miniseries will dive deep into the cellular structures, human systems, and overall anatomy that work together to keep our bodies going. Using the visual structure and quick pacing of Seekers Sick series, these human bio-focused episodes will give a new audience an inside look on whats happening inside all of us.
