What Is The 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.
How Does The Immune System Work?
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.
Leukocytes are divided into two types:
Phagocytes:
These cells surround the pathogens and end up absorbing (eating) them. There are several types of phagocytes, such as neutrophils, monocytes, macrophages, and mast cells.
Lymphocytes:
These help the body keep a check of previous invaders. These cells begin their life in the bone marrow and differentiate into B cells and T cells. While the B lymphocytes produce antibodies and alert the T cells, the latter destroys the corrupt cells and alert other leukocytes.
Signs And Symptoms Of A Weak Immune System
When your immunity is at stake, you will observe the following signs:
- Cold hands, fingers, toes, ears, or nose
- Diarrhea that lasts for more than a week

These symptoms may also be due to some other health condition and not necessarily because of weak immunity.
What Causes Low Immune Function?
There are four major causes of weak immunity. They include:
- Stress
- Inadequate exercising
- Malnutrition
- Sleep deprivation
Other risk factors that can make your immune system weak are:
- Age: Newborns, children, and older adults are more likely to have weaker immunity.
