In the human host, malarial parasite Plasmodium initially infects liver cells as sporozoites and then enters:
| 1. | Red blood cells as merozoites causing fever through hemoglobin digestion and RBC rupture |
| 2. | White blood cells as gametocytes suppressing immune response against parasite |
| 3. | Nerve cells as trophozoites leading to cerebral complications and coma |
| 4. | Lymph nodes as schizonts multiplying rapidly before entering bloodstream |

The malarial paroxysm is characterized by chills and high-grade fever. This is associated with-
| 1. | Rupture of liver cells when the parasite multiplies in the liver cells |
| 2. | Inoculation of the sporozoite by the mosquito into human blood |
| 3. | Release of hemozoin due to rupture of RBC by the parasite |
| 4. | Development of the adult trophozoite in the RBC |
