Immunity is the capability of multicellular organisms to resist harmful microorganisms from entering their cells. Immunity involves both specific and nonspecific components. The nonspecific components act as barriers or eliminators of a wide range of pathogens irrespective of their antigenic make-up.
Immunity is the capability of multicellular organisms to resist harmful microorganisms from entering their cells. Immunity involves both specific and nonspecific components. The nonspecific components act as barriers or eliminators of a wide range of pathogens irrespective of their antigenic make-up. Other components of the immune system adapt themselves to each new disease encountered and can generate pathogen-specific immunity.
Innate immunity, also called native immunity, is defined by the organism’s original genetic make-up and does not adapt to particular external stimulation or a previous infection. It is divided into two types:
•Non-Specific innate immunity, a degree of resistance to all infections in general.
•Specific innate immunity, a resistance to a particular kind of microorganism only.
Adaptive immunity can be sub-divided by how the immunity was acquired: ‘naturally acquired’ through chance contact with a disease-causing agent, or ‘artificially acquired’ through deliberate actions such as vaccination. Both naturally and artificially acquired immunity can be further subdivided based on whether the host immune system developed immunity itself or through vaccination. ‘Active immunity’ lasts long-term, sometimes lifelong. ‘Passive immunity’ is acquired through the transfer by of antibodies or activated T-cells derived from an immune host; it is short-lived—usually lasting only a few months—requiring booster doses for continued immunity.
Why immunity is important?
It protects your body from harmful substances, germs and cell changes that could make you ill. It is made up of various organs, cells and proteins.
As long as your immune system is running smoothly, you don’t notice that it’s there. But if it stops working properly – because it’s weak or can’t fight particularly aggressive germs – you get ill. Germs that your body has never encountered before are also likely to make you ill. Some germs will only make you ill the first time you come into contact with them.

3.Consume More Zinc
Increase food sources of zinc to prevent deficiency; zinc is responsible for activating white blood cells that are essential for our immune system.

4.Get More Vitamin D
Consume adequate vitamin D from a combination of sun exposure (limited to about 15 minutes/day without sunscreen), food, and supplements; while dietary supplements are typically not necessary if you eat a balanced diet, vitamin D is the one exception because food sources are limited.
5.Sleep
Sleep is crucial for maintaining a healthy immune system in order to prevent susceptibility to illness and recover quickly.Most adults should get 7 to 9 hours per night.
6.Stay Active
Since your gym or favorite workout class is likely unavailable, take advantage of the spring weather and get outdoors for some physical activity, such as running.
