Non-Specific Immunity Concepts

The video explains non-specific immunity, also known as innate immunity, which is the body's immediate response to pathogens like viruses and bacteria. Using a war zone analogy, it describes how the body's defenses, such as skin and blood cells, act as barriers and soldiers to protect against invaders. The role of red and white blood cells, particularly macrophages, in engulfing and destroying pathogens through phagocytosis is detailed. The video also highlights the limitations of non-specific immunity and introduces the concept of adaptive immunity, which is more effective in dealing with persistent threats.

What is another term for non-specific immunity?

• Adaptive immunity

• Innate immunity

• Acquired immunity

• Passive immunity

In the war zone analogy, what do the soldiers represent?

• Immune cells

• Bacteria

• Viruses

• Pathogens

What is the primary function of erythrocytes?

• To engulf pathogens

• To produce antibodies

• To carry oxygen

• To fight infections

Which type of cell is known for engulfing pathogens?

• Erythrocytes

• Neurons

• Macrophages

• Platelets

What is the process called when a macrophage engulfs a pathogen?

• Pinocytosis

• Phagocytosis

• Exocytosis

• Endocytosis

What organelle in macrophages contains toxic substances to destroy pathogens?

• Mitochondria

• Nucleus

• Ribosome

• Lysosome

Why is non-specific immunity considered slow?

• It targets specific pathogens

• It uses the same method for all pathogens

• It requires antibody production

• It relies on external factors

What is a limitation of non-specific immunity?

• It is too fast

• It only targets viruses

• It is too specific

• Some pathogens can survive it

What is another name for specific immunity?

• Non-specific immunity

• Innate immunity

• Passive immunity

• Adaptive immunity

What happens when non-specific immunity is not effective?

• The body remains healthy

• Pathogens build up and cause illness

• Pathogens are immediately destroyed

• The immune system stops functioning
