What are examples of non-specific defenses?

The skin and phagocytes are nonspecific defenses, meaning they work to defend us against any foreign pathogen. Inflammation, a tissue-level response to injury or infection, and fever, a systemic response to infection or inflammation, are other examples of nonspecific defenses.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
