hello. how does one reference your work when doing an assignment?
Funny.
Is your white blood cell illustration correct? Everything has a design function; why or how is this shape efficient for movement or flow? So; you are saying each white blood cell is equipped with these sticky feet are these feet only on one side or all around? And you are also saying they in effect are self propelled. What motivates them to move.
You say; “sent”. How are white blood cells sent anywhere? Is it by electrical stimulation or chemical stimulation?
Or is it the flow naturally until a certain obstruction occurs and they literally pile up due to their shape. And the location of injury emits a natural fluid which in-turns consumes the highly nutrient white cells? This extra nutrition helps in the healing of the stationary cells. This is a question not a statement.
I don’t see a single reply to any comments or questions. Surely there are advanced students or practitioners here with some insight..
I’m surprised to see a lack of questions here as well.

I don’t like the word; “theory” when it comes to modern medicine. Particularly when it comes to an animate object you are drawing sketches of. It would seem the word “theory” would be long gone in this field.
It makes the presentation suspect in not being totally complete.
