Before we go any further in this exploration of the gut-immune connection, let’s review some basic concepts of the immune system.
The immune system contains four systems:
1. Organs that produce white blood cells
2. Lymphatic system that circulates those cells
3. The antigens and antibodies your system makes after taking on viruses and other threats
4. Your gut microbiome, which research have found to play a critical role in immunity
Immunity is also divided into two types of responses: innate immunity and adaptive immunity. Innate immunity acts as our first line of defense and is composed of physical and chemical barriers, immune cells, and blood proteins that mediate inflammation. Certain nutrients, such as vitamin D, are crucial to proper function of innate immunity.
When innate immunity is insufficient to manage a threat, the adaptive immune system steps in to tackle the more complex immune responses. Lymphocytes, called B and T cells, are responsible for antigen production and cell-mediated immunity. Through adaptive immunity, lymphocytes survey our body continuously, looking for potential pathogens.
Check to make sure your vitamin D levels are optimal and engage your lymphatic system with movement and lymphatic drainage therapy.
