artificially acquired passive immunity
naturally acquired active immunity
artificially acquired active immunity
question 13 (1 point)
which of the following is not a sign of inflammation?
mucus production
heat
swelling
pain
redness

Explanation:

First Question (Adaptive Immunity):

1. Understand Adaptive Immunity Types:

• Active Immunity: Body produces its own antibodies (e.g., from infection or vaccine).
• Passive Immunity: Antibodies are received from an external source (no immune response activation).
• Natural: Occurs without medical intervention (e.g., maternal antibodies).
• Artificial: Induced by medical means (e.g., injection of immunoglobulins).

1. Analyze the Scenario: Intravenous injection of immunoglobulins is a medical (artificial) procedure. Since immunoglobulins are antibodies (not triggering the body to make its own), it’s passive. Thus, it’s artificially acquired passive immunity.

1. Recall Inflammation Signs: The classic signs of inflammation are heat, redness, swelling, and pain (sometimes loss of function).
2. Evaluate Options:

• Heat, swelling, pain, and redness are classic signs.
• Mucus production is related to respiratory defenses (e.g., in infections like colds) but is not a core sign of inflammation.

Answer:

B. artificially acquired passive immunity
