Worked Solution & Example Answer:A fisherman pricked his finger on a fish hook - HSC - SSCE Biology - Question 25 - 2009 - Paper 1
Step 1
Identify TWO defence adaptations used by the body in response to the injury.
Answer
-
Inflammation: The injured area becomes red and swollen due to increased blood flow and immune cell activity, which helps to isolate and eliminate pathogens.
-
Pain Response: The throbbing sensation is part of the body's defense mechanism to signal injury and discourage the use of the affected part, facilitating healing.
Step 2
Identify the role of the antibiotics in the management of this injury.
Answer
Antibiotics are prescribed to prevent bacterial infection from developing at the site of the injury. They work by inhibiting the growth of bacteria that could potentially invade the wound, thus reducing the risk of complications such as severe infections.
