Review the major aspects of how the human immune system functions.
According to Nicholson (2016), the human body immune system offers security to the
body tissues against illnesses by constantly offering surveillance on the various body organs and
cells. It is worth noting that the white blood cells are the major elements of the immune system.
Most of the elements of the immune system are produced in the bone marrow and undergo
conditioning and enhancements before being released to fight antigens and other toxins in the
body. It is worth noting that the human body system has at least five different types of white
blood cells (Nicholson, 2016). What is fascinating about the classification of the white blood
cells is the fact that they can be categorized into many other groups depending with the proteins
manifesting in them. The protein components that differentiate the various white blood cells
usually manifest on the cell membranes of the cells. One of the protein types on the membrane of
white blood cells is receptors, which help the cells during interaction and communication with
one another (Yatim & Lakkis, 2015). The main types of white blood cells include monocytes,
lymphocytes, neutrophils, and basophils or eosinophils.
In consideration to the working mechanism of white blood cells, neutrophils are usually
the early responders to a potential risk to the body system. They respond by phagocytosis and
local killing, which is the mechanism of engulfing the antigens and destroying them internally. In
case the function of the neutrophils is not effective in countering the infection, the body
immunity will respond by sending the lymphocytes, which are adapted to study and work on
eliminating the threat as soon as possible (Nicholson, 2016). The lymphocytes are divided into
the B-cells and the T-cells. The T-cells are responsible for killing the presenting infection and
antigens whereas the B-cells help in the production of the antibodies to fight off the antigens.
