To remove necrotic cells and tissues
B
To decrease blood flow to the affected area
C
To eliminate the initial cause of cell injury
D
To facilitate tissue repair
Verified step by step guidance1
Understand the primary functions of inflammation: Inflammation is a biological response to harmful stimuli, such as pathogens, damaged cells, or irritants. Its main functions include eliminating the initial cause of cell injury, clearing out necrotic cells and tissues, and initiating tissue repair.
Analyze the options provided: The options include removing necrotic cells and tissues, decreasing blood flow to the affected area, eliminating the initial cause of cell injury, and facilitating tissue repair.
Recall that inflammation typically involves increased blood flow to the affected area, not decreased blood flow. This increased blood flow helps deliver immune cells and nutrients necessary for healing.
Identify the option that does not align with the typical functions of inflammation: Since inflammation usually increases blood flow to support the healing process, the option 'To decrease blood flow to the affected area' does not fit the typical functions of inflammation.
Conclude that the correct answer is the option that does not describe a function of inflammation, which is 'To decrease blood flow to the affected area.'
