Antígeno

The video tutorial explains the immune response, focusing on how the body produces specific antibodies to combat antigens. Antigens are typically molecules found on the surfaces of bacteria, viruses, or other microorganisms. Some non-microbial antigens, like pollen, can also trigger an immune response.

What is the primary function of the immune system?

• To produce hormones

• To generate specific antibodies

• To regulate body temperature

• To digest food

What are antigens typically composed of?

• Proteins and carbohydrates

• Lipids and nucleic acids

• Water and minerals

• Molecules from bacteria surfaces

Where are antigens commonly found?

• In the digestive tract

• In the bloodstream

• Inside the nucleus of cells

• On the surface of bacteria and viruses

Which of the following is an example of a non-microbial antigen?

• Fungi

• Virus

• Bacteria

• Pollen

How can non-microbial antigens affect the body?

• By causing infections

• By generating an immune response

• By reducing blood pressure

• By increasing metabolism
