Painting of Cholestrol and LipoProtein:Cholesterol does not travel alone in the bloodstream. It is unable to circulate freely in blood because it is a fat-like substance and blood is more watery.Instead, cholesterol combines with a protein that allows it to become more soluble in the blood. This...

Painting of monocytes:Monocytes are usually identified in stained smears by their large bilobate nucleus.Monocytes are produced by the bone marrow from haematopoietic stem cell precursors called monoblasts. Monocytes circulate in the bloodstream for about one to three days and then typically move...
