true
false
question 2 (2.5 points)
an example of a cellular response to tissue injury is
a) neutrophil diapedesis
b) vascular permeability
c) swelling
d) vasodilation

Explanation:

• For Question 1: The skin contains melanin which helps to absorb and scatter UV - radiation, reducing its harmful effects on the body.
• For Question 2: Neutrophil diapedesis is the process by which neutrophils move from the bloodstream into the tissues at the site of injury as part of the cellular immune response. Vascular permeability, swelling, and vasodilation are more related to vascular or tissue - level responses rather than cellular ones.

Answer:

Question 1: True
Question 2: a) neutrophil diapedesis
