Final answer:
In cases of tissue inflammation, the highly permeable lymphatic capillaries develop openings that allow for the uptake of pathogens and cancer cells. This permeability facilitates the body's immune response to injury or infection and aids in the subsequent healing process.
Step-by-step explanation:
When tissues are inflamed, the lymphatic capillaries develop openings that permit uptake of both pathogens and cancer cells, so the correct answer is b and c. These capillaries are known for their high permeability, which allows them not only to absorb excess fluid from interstitial spaces but also to transport larger molecules such as fats and cellular debris. Inflammation causes capillaries to dilate and become more permeable, thus enabling an increased flow of inflammatory and immune responses, which includes the migration of white blood cells that target and destroy pathogens. The immune system also deploys cytokines and histamines to manage the inflamed tissue, facilitating the transport of antigens to lymph nodes to form an adaptive immune response.
