Which of the following is true regarding the inflammation cascade?Group of answer choicesPermeability of the vessels decreaseLeukocytes travel away from the site of the infectionChemical mediators lure leukocytes to the site of injury or infectionInflammation is always considered a negative response to injury or infection
Solution
The correct statement regarding the inflammation cascade is: "Chemical mediators lure leukocytes to the site of injury or infection."
Here's why:
-
Permeability of the vessels decrease: This is incorrect. During inflammation, the permeability of the vessels actually increases to allow immune cells, like leukocytes, to reach the site of infection or injury more easily.
-
Leukocytes travel away from the site of the infection: This is also incorrect. Leukocytes, or white blood cells, are part of the immune response and they travel to the site of infection or injury to help fight off the foreign invaders.
-
Chemical mediators lure leukocytes to the site of injury or infection: This is correct. Chemical mediators such as histamine, cytokines, and chemokines are released at the site of injury or infection. These substances attract leukocytes to the site, a process known as chemotaxis.
-
Inflammation is always considered a negative response to injury or infection: This is incorrect. While inflammation can cause discomfort and sometimes damage, it is a crucial part of the body's immune response to injury or infection. Without inflammation, our bodies would not be able to heal from injuries or fight off infections effectively.
