Answer: The correct answer is b) Blisters that contain clear, watery fluid.
Explanation:
Vesicles and bullae are both types of blisters that form on the skin.
Vesicles are small blisters, typically less than 1 cm in diameter. They contain clear, watery fluid and are often seen in conditions such as chickenpox, herpes, or contact dermatitis.
Bullae, on the other hand, are larger blisters that are greater than 1 cm in diameter. They also contain clear, watery fluid. Bullae can be caused by burns, severe sunburns, or certain skin conditions such as bullous pemphigoid.
It's important to note that vesicles and bullae are not the same as pustules, which contain pus (a thick, yellowish fluid) rather than clear fluid. Malignant tumors are cancerous growths, which are unrelated to the formation of blisters. Forms of edema involve the accumulation of excess fluid in the tissues, but they are not specifically associated with the formation of blisters.
In summary, vesicles and bullae are blisters that contain clear, watery fluid
