| 0:00.0 | Let's talk about lymph nodes and what they are. A lot of people don't really know exactly |
| 0:18.8 | what a lymph node is in relationship to your immune system. Now, the lymphatic system |
| 0:24.7 | is really an extension from your circulatory system. And so all this blood rushes through the |
| 0:30.7 | body and it goes into the tissues. And then from the tissues, it turns into lymph and goes |
| 0:36.7 | through the lymphatic system. Now, the lymphatic system does not have a pump. So it's pumped through |
| 0:42.8 | the body through muscular movement. So when all this lymph flows up to the body, it gets dumped |
| 0:47.8 | back into the circulatory system. It's kind of a backup drainage system to prevent excess fluid |
| 0:54.6 | retention as in lymphedema. However, that's a minor function. The big function and the most |
| 1:01.4 | important function is the activation of your immune system. You will have an entire war going on |
| 1:08.3 | within your lymph nodes if there is a pathogenic microbe. And the pathogen is a microbe that can |
| 1:16.9 | cause disease. One of the purposes of a lymph node is to contain and hold off a pathogen. |
| 1:23.6 | It can protect the pathogen from spreading throughout the body. So that's why you have lymph nodes |
| 1:28.2 | in your armpits to prevent pathogens from invading your whole arm. Or even in the back of your |
| 1:33.8 | throat as the tonsils, you have lymph nodes in the side of your neck. You have them throughout |
| 1:38.2 | the abdomen area into the groin. There's hundreds of lymph nodes through the body. And the largest |
| 1:44.5 | lymph node is this bling, which is located underneath the rib cage on the left side over here. |
| 1:51.2 | Let's just take a look at what is inside a lymph node. Well, you have lymphocytes. |
| 1:59.2 | Those are immune cells that do their work inside the lymphatic system, but they can also come |
| 2:05.0 | outside the lymphatic system and travel around to the tissues. There's three primary lymphocytes. |
| 2:11.6 | One would be the natural killer cells. These cells are like part of your special forces. |
| 2:17.8 | They specialize in killing viral infected cells. So when the virus invades a cell, |
| 2:26.1 | they will kill the entire cell and the virus together. Also, they will attack tumor cells |
