Define CO2 toxicity and its potential effects on the human body.

Answer 2

CO2 toxicity refers to the harmful effects of elevated carbon dioxide levels in the body, which can lead to drowsiness and even act as a sleep-inducing agent.

Question 3

How does disruption of the respiratory epithelium contribute to bacterial infection in the respiratory system?

Answer 3

Disruption of the respiratory epithelium, similar to the skin, allows commensal bacteria to enter and cause damage, leading to local or systemic infections.

Question 4

What are the potential consequences of bacteria entering the bloodstream from a respiratory infection?

Answer 4

Bacteria entering the bloodstream from a respiratory infection can lead to a systemic infection known as septicaemia.

Answer 7

While good viruses generally align with the public’s understanding of infections, there are examples like herpes and chickenpox that persist and may not fit the typical paradigm.

Question 8

Describe the potential consequences of a local disruption of the respiratory epithelium.

Answer 8

A local disruption of the respiratory epithelium can lead to a local infection, while a deeper penetration can result in systemic infections like septicaemia or pneumonia.
