Analysis of Blood cells

Starts in vesicle between cell layers
These cells raft up, their nuclei add up
Some attract proto in hues, raft stayers
Walls gone, proto wrapped nucleus bob up

Red blood cells formed, floats through capillary
Blood-vessels, these are embryonic in
Nature, replaced by red corpuscles, wee
Ones, Adult “corps” form same way, that's within

Connective tissue, then they connect with
Above mentioned blood-vessels, bone marrow
Is source in post embryonic forthwith
These cells will then lose nuclei, narrow

In middle (Biconcave), white cells: lymph form
Two types, others in marrow and tissue.

Alkaline plasm, one tenth solids, norm
Four fifths are protieds, rest are soap in stew

Salts, fat and food nutrients. Two serum
(Albumin, globulin),fibrinogen
Are the three protieds, latter premium
When air hits blood, it's joined by Thrombin, when

Things folks ignore(white cells and platelets) die
This forms fibrin(guess what's next?) which wraps round
To clot corpuscles. Human blood differs, bespy
Crystals, not like animal blood, are found
