White blood cells
Neutrophils are typically the first immune cells to leave the blood and enter infected tissues in response to an infection. They play a critical role in the early stages of the inflammatory response by phagocytizing pathogens and releasing inflammatory mediators.
-White blood cells White blood cells are like policemen in bloodstream. They are constantly on patrol for infected cells. (Yes; they usually eat them -aka kill them.)
NO
when female anopheles mosquito take a blood meal from a host with malaria, the mosquitoe took the malaria bacteria's gametes with the blood meal. the gamestes fused together in the mosquitoe's gut forming the infected stage. if the mosquito then bit a non infected human host, the infected stage of the bacteria will enter the bloodstream vai the salivary gland of the mosquito.

Infected cells are typically referred to as host cells that have been invaded by a virus, bacteria, or other microorganism.
Blood contains red blood cells. Red blood cells don't contain blood. Blood does not enter the red blood cell.

White blood cells
The cells you are referring to are called natural killer (NK) cells. NK cells are a type of white blood cell that plays a crucial role in the immune system by identifying and eliminating cancerous cells and virus-infected cells in the body. They are part of the body's innate immune response.
White blood cells produce antibodies to diseases. The antibodies enter the bloodstream and prevent a specific disease from recurring. One type of white blood cells, called B cells, manufacture and release the antibodies. Another type, called T cells, does the job of penetrating the infected cells so that the antibodies can do their work.
