What stage moves from the liver stage to the blood stage?

Explanation:
The key idea is how malaria parasites move from liver to blood. After a mosquito bite, sporozoites reach the liver and multiply, forming merozoites within hepatocytes. These merozoites are then released into the bloodstream, where they invade red blood cells to start the asexual blood-stage cycle. So the stage that moves from liver into the blood to begin erythrocytic infection is the merozoite. Hypnozoites are dormant liver forms (not the immediate liver-to-blood transition), and gametocytes are the sexual stages that develop in red blood cells and are taken up by mosquitoes.
