Briefly describe the process of inflammation in an area that has been traumatized.
Inflammation is a complex response that occurs when body tissues are injured. During injury, blood arteries in the afflicted area become wide, which increase blood flow and allow proteins and immune cells to enter the tissue. On the other hand, white blood cells, specifically neutrophils and macrophages, progress to the site of injury, phagocytosing debris and combating possible dangers. Cells produce cytokines at the same time to coordinate immune responses. As the anti-inflammatory process moves, fibroblast helps to repair tissue by generating collagen, and anti-inflammatory signals attempt to remove the inflammation once the threat has been eliminated. In most cases, like prolonged or chronic inflammation, there’s a possibility for it to contribute to a variety of health problems.

Choose one type of Immunity (Innate and Humoral) and explain how its mechanism protects our body.
Innate immunity, the primary defense against infections. Innate immunity is active from birth, providing immediate, non-specific protection against a wide range of invaders. In contrast to adaptive immunity, which includes humoral and cell-mediated responses customized to specific pathogens, innate immunity lacks antigen specificity and does not provide persistent immunity after infection. It functions as a quick and always ready non-specific defense mechanism. This natural defense mechanism responds quickly to a wide range of infections and serves as the body's first line of defense in the immune response. The skin is an example of innate immunity since it acts as a protective shield, preventing pathogens such as bacteria and viruses from entering the body.
