Arrange in a sequential manner the life cycle of the malaria parasite in the human host

A. Merozoits enter red cells

B. Multiplication in liver

C. Sporozoites enter the human host

D. Human blood enters the mosquito

E. Infected mosquito bites a person

Choose the correct answer from the options given below:

The correct answer is E, C, B, A, D.

Explanation:

• Infected mosquito bites a person - When an infected female Anopheles mosquito bites a person, it injects sporozoites into the bloodstream.
• Sporozoites enter the human host - The sporozoites travel to the liver and invade liver cells, where they multiply and develop into merozoites.
• Multiplication in liver - The merozoites are released into the bloodstream and invade red blood cells, where they continue to multiply asexually.
• Merozoites enter red cells - The infected red blood cells eventually burst, releasing more merozoites into the bloodstream.
• Human blood enters the mosquito - When an uninfected mosquito bites an infected person, it ingests the merozoites.

​

Hence, the correct sequential order of the life cycle of the malaria parasite in the human host is E, C, B, A, D.
