Blood in General

Blood is a bodily fluid that carries nutrients to different parts of the body and filter it from different kinds of bacteria. It contains the following three things: Erythrocytes, Leukocytes, and Thrombocytes. Blood produced by bone in the red bone marrow which is a thick red substance located in the middle of the bone. Their production is controlled by different hormones, chemicals, and stem cells. Examples of these cells are Erythropoietin and Leukopoeitin.


Plasma is a yellow liquid that lays on top of blood cells when separated. It gives blood it's liquid characteristic. It's 55% of the entire blood in general. Transports nutrients and proteins to maintain homeostasis. Plasma is separated from the blood by putting it in a centrifuge machine and spinning it around really fast. Plasma is possible to donate and you can get paid for it too. The reason you get paid is because plasma can be provided for research and also for burn victims and people with clotting disorders. It takes hours to donate plasma so people who donate are paid for their times and troubles.

Erythrocytes (Red Blood Cells)

Contain no nucleus

Created in red bone marrow

Their basic function is to carry nutrients and oxygen to the heart.

Platelets (Thrombocytes)

Platelets are tiny cells within the blood, these are responsible for coagulation. They're smaller than the red and white blood cells and are more rare than them.
