Answer 1

Answer:

The feature of WBCs that makes them particularly important in tissue injury is that they can squeeze out through blood vessel walls into tissues.

Step-by-step explanation:

This process is called diapedesis or extravasation, and it allows white blood cells to move from the bloodstream into the surrounding tissues in response to inflammation or infection. Once in the tissues, white blood cells can fight infections, remove dead or damaged cells, and promote tissue repair.

During diapedesis, white blood cells use specialized proteins to adhere to the walls of blood vessels and to squeeze through gaps between the endothelial cells that make up the vessel wall. This allows them to enter the tissue and respond to the injury or infection.

Therefore, the ability of white blood cells to leave the bloodstream and enter tissues makes them particularly important in tissue injury.
