In this podcast, we're going to talk about lymph nodes and your immune system.
You can think of the lymphatic system as a back-up drainage system to prevent excess fluid retention. But, this is just a minor function. The big function is the activation of the immune system.
One of the purposes of the lymph nodes is to keep a pathogen from spreading throughout the body. You will have an entire war going on within the lymph nodes if there is a pathogenic microbe.
A person has hundreds of lymph nodes throughout the body. Inside of a lymph node, there are lymphocytes. There are three primary lymphocytes:
1. Natural killer cells (kill viral-infected cells)
2. T cells (kill specific microbes and determine self from non-self)
3. B cells (make antibodies)
Inside of the lymph node:
• There are a lot of antibody reactions going on
• The immune system presents tiny parts of pathogens to the T cells
• There is a lot of lymph-blood exchange
• It filters certain cancer cells
The spleen is the largest lymph node. When someone has their spleen out, they have an increased risk of infection. Chronic stress activates cortisol, which then can shrink the lymphatic system. A zinc deficiency is another thing that can cause issues with the spleen and the entire lymphatic system.

| 0:36.0 | Let's talk about lymph nodes and what they are. |
| 0:39.3 | A lot of people don't really know exactly what a lymph node is in relationship to your immune system. |
| 0:44.3 | Now, the lymphatic system is really an extension from your circulatory system. |
| 0:50.3 | And so all this blood rushes through the body and it goes into the tissues. And then from the |
| 0:55.6 | tissues, it turns into lymph and goes through the lymphatic system. Now the lymphatic system |
| 1:01.4 | does not have a pump. So it's pumped through the body through muscular movement. So when all this |
| 1:07.9 | lymph flows up to the body, it gets dumped back into the circulatory system. |
| 1:12.2 | It's kind of a backup drainage system to prevent excess fluid retention, as in lymphedema. |
| 1:19.1 | However, that's a minor function. |
| 1:21.5 | The big function and the most important function is the activation of your immune system. |
| 1:30.3 | You will have an entire war going on within your lymph nodes if there is a pathogenic microbe. And a pathogen is a microbe that can cause |
| 1:39.4 | disease. One of the purposes of a lymph node is to contain and hold off a pathogen. You can protect the |
| 1:46.4 | pathogen from spreading throughout the body. So that's why you have lymph nodes in your armpits |
| 1:51.1 | to prevent pathogens from invading your whole arm or even in the back of your throat is the tonsils. |
| 1:57.4 | You have lymph nodes in the side of your neck. You have them throughout the abdomen area into the |
| 2:02.1 | groin. There's hundreds of lymph nodes to the body. And the largest lymph node is this spleen, which is located |
