GENERAL HISTOLOGY

Detailed explanation-1: -Cytokines attract the attention of certain cells to start healing your cut. They also alert your immune system to scan for infection in the injured area. You will notice the injured area swelling and getting red as all the cells that the cytokines called rush to the scene. This swelling is called inflammation.

Detailed explanation-2: -The first responders are cells known as neutrophils and these remove foreign material and bacteria from the wound. The next wave of immune cells to arrive at the scene includes monocytes. These cells normally reside within the spleen and bone marrow, and can be mobilized in response to injury or infection.

Detailed explanation-3: -White blood cells are the key players in your immune system. They are made in your bone marrow and are part of the lymphatic system. White blood cells move through blood and tissue throughout your body, looking for foreign invaders (microbes) such as bacteria, viruses, parasites and fungi.
