Question

which of the following is not one of the bodys defense mechanisms against infection? a. fever b. high blood pressure c. mucus in the nose d. coughing

Explanation:

• Fever: It is a defense mechanism. When the body is infected, the immune system may raise the body temperature to create an environment less favorable for pathogens and also enhance immune cell activity.
• High blood pressure: This is a condition related to the force of blood against the artery walls. It is not a normal, direct defense mechanism against infection. It is often a chronic health issue (like in hypertension) that can have various causes (e.g., lifestyle, genetics) and is not part of the body's immediate or general infection - fighting strategies.
• Mucus in the nose: It traps pathogens (such as bacteria, viruses) and dust particles, preventing them from entering the respiratory tract further and causing infection.
• Coughing: It helps to expel foreign substances (including pathogens) from the respiratory system.

Answer:

B. High blood pressure
