What is the immune system and how does it work inside the body?
The immune system is a complex biological defense system that protects the body from pathogens such as:
-
Viruses
-
bacteria
-
fungi
-
parasites
-
cancer cells
The immune system consists of several key components, including:
🔬 1. Immune cells
like:
-
white blood cells
-
lymphocytes
These cells recognize and attack foreign bodies.
🧬 2. Antibodies
These are proteins produced by the immune system to recognize pathogens and prevent their spread within the body.
🦠 3. The lymphatic system
It helps in transporting immune cells and defensive fluids within the body.
🛡️ 4. Natural defensive barriers
like:
-
skin
-
mucous membranes
-
stomach acids
These barriers act as a first line of defense to prevent microbes from entering.
Why does the immune system weaken?
Medical studies indicate that weakened immunity may be caused by several factors, including:
-
malnutrition
-
lack of sleep
-
chronic psychological stress
-
Smoking
-
Lack of physical activity
