INJURY1
A human body is flexible and adaptive to the external stimuli in most of the cases but
sometimes it has its own ways to respond to certain type of external actions. Injuries are a form
of external action that alters the reaction of the body and it starts a number of mechanisms and
pathways to react to the pain. The first reaction of the body to an injury is an inflammatory
response because the aim is to heal. The first stages of the inflammatory response is heat, pain,
redness and swelling. Laceration is a form of injury that causes the tearing of skin and it leads to
an irregular wound as it caused by blunt forced object or a rapid force.
In this case study Daniel is a 62 years old and a builder due to his occupation. He has a
history of cardiovascular disease and because of that he felt dizzy while he was working, which
resulted to his fall that led to a laceration in his lower left leg. The defense of the body towards a
laceration is an inflammatory pathway that involves the immunity system (Dudley, 2016). It is an
immune system system’s response towards harmful stimuli such as toxic compounds, damaged
cells, and pathogens. It prepares the body for removing the injurious stimuli initiating the process
of healing. There are two types inflammation, which is known as acute and chronic, and the body
responds to both of them accordingly (Thomopoulos et al., 2015). When an acute injury occurs,
the inflammatory process starts to bring together the molecular and cellular events or interactions
to reduce the infection or the injury. This process is the mitigation that contributes to the
restoration of resolution of the acute inflammation and tissue homeostasis. When the acute
inflammation is not controlled by the body then it can cause chronic inflammation that can lead
to severe chronic diseases. Laceration in the tissue level has an inflammation that is followed by
swelling, redness, loss of tissue function, heat and pain. This happens due to the local immune,
inflammatory and vascular cell responses to the injury or infection. Some of the microcirculatory
events that occur during the process of inflammation are leukocyte recruitment and
