Illustration of the second phase of malaria transmission from one organism to another. The parasites (merozoites) move through blood vessels to the lungs where immune surveillance is lower and blood flow slower. They break out of their envelope (made by the liver). They penetrate red blood cells, ultra rapid transporters that allow them to avoid the filtering spleen. They proliferate in their shelter until, after 48h, they blow up the cell membrane, spread through the blood and quickly parasite other red blood cells to proliferate once more. An immune reaction starts up and the infected person has a high temperature. After a few cycles, the person is tired as the red blood cells no longer carry enough oxygen. Cell residue stuck to blood vessel lining.
