Blood accounts for 7% to 8% of body weight in a normal adult.

So someone like my master who weighs 50KG

There are about 3.5-4 liters of me in his body.

I am made up of red blood cells, white blood cells,

Platelets, plasma, etc.

『Red blood cells』

Mainly responsible for transporting oxygen

Can help patients with anemia and severe blood loss

"leukocyte"

Can devour bacteria that enter the human body

Because it may cause adverse reactions

Therefore, some patients may

Need to transfuse blood that has been filtered to remove white blood cells

Platelets

Can help various reasons

Patients with thrombocytopenia

or patients with impaired platelet function

"plasma"
