WHAT IS THE IMMUNE SYSTEM?

The immune system is made up of specialized cells, proteins, tissues and organs in the body that work together to help keep the body healthy.1

The immune system doesn’t have one centralized location in the body like the heart or the brain. Instead, the immune system is a complex system of organs, tissues, and cells located throughout the body.1 This includes the thymus, bone marrow, spleen, tonsils, lymph nodes, and adenoids.1

WHAT ARE THE TWO MAIN PARTS OF THE IMMUNE SYSTEM?

The different parts of the immune system serve different functions to help keep you healthy.

INNATE IMMUNITY

Everyone is born with innate immunity (a.k.a. natural immunity) as a form of general protection against foreign invaders.2 This is the body’s first line of defense against foreign invaders.

EXAMPLE

Your skin! It acts as a physical barrier to help block germs from entering the body.2

ADAPTIVE IMMUNITY

There are two parts of adaptive immunity: active immunity and passive immunity.2

ACTIVE IMMUNITY

This immunity develops over the course of our lives as we are exposed to pathogens.3

EXAMPLE

Exposure to a pathogen stimulates the production of specific immune cells that mark the pathogen for instruction. The immune cells can then “remember” that pathogen if they’re exposed to it again and can properly respond.3

PASSIVE IMMUNITY

It’s short-lived, but helpful! This type of immunity typically lasts a short time and is gained through another source, rather than being produced by a person’s own immune system.3

EXAMPLE

An infant can receive antibodies through a mother’s breast milk and a newborn receives passive immunity from its mother’s placenta.3

WHY DO YOU NEED A HEALTHY IMMUNE SYSTEM?

A healthy immune system protects your body from invaders, otherwise known as antigens, like bacteria and viruses, by preventing them from entering. Should any of these antigens make their way into the body, a healthy immune system is built to destroy them before they reproduce.1

SUPPORTING THE IMMUNE SYSTEM

There are several ways to help support your immune system, including a combination of the following practices:1,4

GETTING ENOUGH SLEEP

by aiming to snooze for a minimum of 7 hours each night for adults, 8-10 hours a night for teens, and up to 14 hours for younger children and infants.4

WHAT ARE WAYS TO SUPPORT THE IMMUNE SYSTEM?

Help support your immune system by practicing good hygiene, managing stress, eating a nutritious diet, exercising regularly and getting enough sleep.
