The right answer is C.
During inflammation, under the influence of chemical mediators, endothelial cells (forming the blood vessels) become activated. This leads to local arteriolar vasodilation then capillary2 which causes:
** an increase in blood supply
** a decrease in the speed of blood flow
This local swelling of the blood vessels causes redness and the sensation of heat. It aims to increase the flow of blood to evacuate dead cells and toxins (detox) and provide the elements necessary for healing, including white blood cells to fight against foreign bodies.
<span>This answer seemed to come very easy. We are daily surrounded by people suffering from cancer. The cancer is cancer cells. Cancer cells crowd out our normal cells and feed off of nutrients within us to continue to grow and multiply.</span>
<span>Tight junctions, at the site of a tight junction, cells are held tightly against each other by many individual groups of tight junction proteins called claudins, each of which interacts with a partner group on the opposite cell membrane. For example, the tight junctions between the epithelial cells lining your bladder prevent urine from leaking out into the extracellular space.</span>
There was less of it, making it more possible for the species to be extinct.
