Worked Solution & Example Answer:When tissue is damaged, mast cells release histamine which immediately results in A - Scottish Highers Human Biology - Question 19 - 2016
Step 1
Choose the correct option based on the immediate action of histamine
Answer
When tissue is damaged, the immediate release of histamine by mast cells leads to increased localized blood vessel dilation and capillary permeability, facilitating better circulation and allowing immune cells to access the affected area more effectively. Thus, the correct option is:
C. increased localised blood vessel dilation and capillary permeability.
