The Immune & Lymphatic Systems Intro + Inflammation & Autoimmune Diseases
Overview
In this lesson, we introduce the anatomy (structure) and physiology (functions and relationships) of the immune and lymphatic systems.
Objective
Gain an understanding of the foundational anatomy and physiology of the immune and lymphatic systems.
What You'll Get
Describe the purpose of the immune system and how it works. Name the elements that make up the immune system and explain how the lymphatic system relates. Explain the role of the lymphatic system and a key understanding regarding how it functions. Describe innate and adaptive immunity and the two primary types of immune dysfunction. Name five examples of immune disorders. Explain why the body gets inflamed and why stress is of such central concern in regard to immunity. Provide some ways to aid in the reduction of inflammation.
Introduction

THE IMMUNE SYSTEM MAKES SURE ALL SYSTEMS WORK PROPERLY
Strong immunity isn’t just important for fending off viruses like the flu during the winter. If you want to be healthy (and happy) then strengthening the immune system is a must. Why? Because its primary goal is to make sure that all systems in your body work properly. – Vivian Michaels
There is a saying: “Be kind, for everyone you meet is fighting a battle you know nothing about.” The point is that we can’t see what’s going on inside others, and therefore we usually don’t know the struggles they are facing. In a similar vein:
- The immune system is invisible to the eye. We may not know if someone is in poor health. Even the individual may not realize the state of their immune system until it is severely compromised.
- And yet, although unseen, the immune system powerfully affects the mind, body and spirit.
What It Does
A well-functioning immune system:
- Prevents illness.
- “Promotes healing by fighting off common infections, healing wounds, and scavenging early cancer molecules.” (Baxter Bell)
