HUMAN DEFENCES AGAINST DISEASE Final Exam Questions and
Graded Answers, 100 % Guaranteed
What are the body's non-specific defences against pathogens? - ✔✔The body employs
various defences such as mucus, cilia, enzymes in tears, skin, and stomach acid to prevent
pathogens from entering.
How does mucus contribute to the body's defence against pathogens? - ✔✔Mucus traps
particles and bacteria, preventing them from entering the body.
What role do cilia play in the respiratory system? - ✔✔Cilia create a wave motion that
sweeps mucus along, helping to clear trapped pathogens.
How do enzymes in tears protect against infection? - ✔✔Enzymes in tears destroy
microorganisms, providing a defence against pathogens.
What is the function of hydrochloric acid in the stomach? - ✔✔Hydrochloric acid kills
bacteria in food, serving as a defence mechanism.
What is the role of sebaceous glands in the immune response? - ✔✔Sebaceous glands
produce sebum, which kills bacteria and fungi.
What happens when a pathogen enters the body? - ✔✔The immune system responds by
trying to destroy the pathogen, primarily through the action of white blood cells.
What is phagocytosis? - ✔✔Phagocytosis is the process by which white blood cells surround,
engulf, and digest pathogens.
What are antibodies? - ✔✔Antibodies are specific proteins produced by the immune system
