Understanding HIV Infection

What is the most common way HIV is transmitted?

• Through animal bites

• Through the air

• Via contaminated food

• By sexual contact

Where are dendritic cells primarily located?

• In the brain

• Within mucous membranes

• In the bloodstream

• In the liver

What is the primary function of dendritic cells in the immune system?

• To produce antibodies

• To destroy pathogens directly

• To sample the environment for threats

• To transport oxygen

How do dendritic cells alert the immune system?

• By changing color

• By increasing temperature

• By displaying antigens

• By releasing hormones

What is a lymph node's role in the immune system?

• To regulate body temperature

• To filter body fluids for pathogens

• To store fat

• To produce red blood cells

Which method is NOT a way HIV is transmitted to lymph nodes by dendritic cells?

• Infectious synapse

• Endocytosis and exocytosis

• Through the digestive system

• Direct infection of dendritic cells

What happens when a dendritic cell becomes infected with HIV?

• It stops functioning

• It produces more HIV particles

• It becomes a red blood cell

• It dies immediately

How does HIV differ from other viruses in its replication process?

• It does not replicate

• It replicates outside the host cell

• It hijacks the host's cellular machinery

• It uses its own machinery

What is the preferred target of HIV particles?

• Skin cells

• Liver cells

• T-helper cells

• Red blood cells

Why is HIV considered more sneaky than other viruses?

• It changes color

• It hides in the brain

• It is visible to the naked eye

• It uses a unique method to hijack cells
