What causes a weakened immune system?
The immune system protects our body from infectious organisms.
It is an integral part of our body’s defense mechanism and is necessary for our
survival. In the absence of an immune system, our body will be open to attacks
from foreign bodies like bacteria, viruses, and other pathogens. Let us now
understand how this complex network of cells, tissues, and organs in our immune
system works towards protecting us.
The immune system consists of a vast
network of tissues and cells that are constantly looking for invading
pathogens. Once the immune system detects a foreign body, it initiates an
attack against the invaders. The immune system is spread throughout our body and is made up
of many tissues, cells, proteins, and organs that can distinguish our body’s
tissues from foreign ones. The immune network also detects dead or abnormal
tissues, which are eliminated from the body. The cells responsible for some of
the major functions of the immune system are the white blood cells. White blood
cells look for pathogens and send signals to other cells of the immune system
to multiply in response to a foreign body while multiplying themselves. These
cells are also known as leukocytes and are stored in different body parts like
the thymus, spleen, bone marrow, and lymph nodes.
