The nurse, learning about malaria, discovers that the transmission of malaria occurs when what is injected into the human body by the infected mosquito?
A) Sporozoites
B) Gametocytes
C) Schizonts
D) Merozoites
A
Feedback:
Gametocytes are sucked with the blood from an infected person by the mosquito. The gametocytes mate in the stomach of the mosquito and produce a zygote that goes through several phases before forming sporozoites (spore animals) that make their way to the mosquito's salivary glands. The next person who is bitten by that mosquito is injected with thousands of sporozoites. Schizonts are the primary tissue organisms resulting from asexual cell division and reproduction after the sporozoites are introduced into the body. Merozoites are then formed from the primary schizonts.
