Medical Are the blood cells just suspended in the liquid we call blood?

AI Thread Summary
Blood consists of approximately 55% plasma, a liquid primarily made up of water and dissolved substances, including nutrients and hormones. The remaining portion comprises solid components, including red blood cells, white blood cells, and platelets, which are crucial for functions like oxygen transport and wound healing. The composition of blood can vary based on individual factors and environmental conditions. Additionally, plasma carries waste products, such as carbon dioxide and other metabolites, which are processed by organs like the lungs, liver, and kidneys.

Is blood completely made up of blood cells, like we are completely made of atoms, or are the blood cells just suspended in the liquid we call blood?

Blood is made up of both plasma about 55% of the volume, the liquid which is mostly water with various chemicals dissolved mostly from our food in it, and some hormones. Red/White blood cells and platelets (involved in sealing wounds) make up the solid part.
 


Oh ok, thanks for the reply Dagda:)
 


as in hematocrit - some estimates of plasma go higher

Indeed it varies from place to place, climate to climate and person to person. That said it's probably a good mean.

I forgot to mention those waste products as well such as CO2 and various organ dumping goes into the plasma as well, to be disposed of by the appropriate organs, lungs, liver, kidneys and so on.
