The immune system and circulatory system work together when you get a small cut. An immune response called the inflammatory response takes place. Why does this response occur?
Question 5 options:
it is preventing another cut from occurring
to aid in digestion for nutrients
it is a defense against pathogens
to slow down blood flow
The correct option is: it is a defense against pathogens.
The inflammatory response is a part of the immune system's defense mechanism to protect the body from harmful pathogens that may try to enter through a cut or injury. It involves various immune cells, such as white blood cells, releasing chemical signals to increase blood flow to the affected area, causing redness and swelling. This increased blood flow helps deliver immune cells and antibodies to fight off any potential pathogens that may have entered the body through the cut.
