Investigating the Immune System Review

The video tutorial explores the immune system, starting with pathogen transmission and disease causation. It covers the body's defense mechanisms, including the inflammatory response, and highlights the main cells and structures of the immune system. The video describes the general processes involved in the immune response and explains various types of immunity. Finally, it discusses challenges the immune system may encounter.

What is the primary way pathogens are transmitted to cause diseases?

• By consuming healthy food

• Through direct contact with infected individuals

• Via exposure to clean environments

• Through regular exercise

Which of the following is part of the body's first line of defense against pathogens?

• White blood cells

• Inflammatory response

• Skin and mucous membranes

• Antibodies

What are the main components of the immune system?

• Red blood cells and platelets

• Neurons and synapses

• White blood cells and lymphoid organs

• Muscles and bones

Which type of immunity involves the production of antibodies?

• Innate immunity

• Adaptive immunity

• Passive immunity

• Cell-mediated immunity

What is one challenge the immune system may encounter?

• Overproduction of red blood cells

• Inability to recognize pathogens

• Excessive muscle growth

• Increased bone density
