Inguinal lymph nodes-located in the groin (inguinal) region.superficial cervical lymph nodes)-found in front of the shoulder blade where the neck and shoulder meet Submandibular lymph nodes-located on either side of the lower jaw where it meets the neck.The following lymph node locations are the easiest to palpate (i.e. But it is much easier to detect enlarged lymph nodes. In some cases, you may be able to feel a hint of the nodes in their normal state (i.e., small). However, there are five sets of peripheral lymph nodes in dogs that are easy to feel. Some lymph nodes are located deep inside the body, such as within the abdomen and along the intestinal tract, where you can’t feel or see them. Lymph nodes are scattered throughout your dog’s body. Eventually the lymph will empty back into the veins of the circulatory system. Lymphocytes from the lymph node will enter the lymph, which flows out of the lymph node and travels to other areas of the body. This may cause the lymph node to swell significantly due to the increased cell numbers. One result of the immune response is a change in lymphocyte numbers and distribution within the lymph node. This activates a cascade of highly complex events necessary to mount an immune response. Inside the lymph node, foreign invaders are filtered out and exposed to a variety of immune cells. With the help of muscle contractions, lymph can flow through lymphatic vessels and into the lymph node. fluid in tissues) has distributed nutrients and picked up things like waste products, foreign invaders, and damaged cells, it drains into lymph vessels to create lymph fluid. This is an important way for the body to send nutrients to the cells within a tissue. The fluid from blood becomes lymphĪs blood flows through the blood vessels, some of the fluid component leaks into the surrounding tissues. Let’s take a closer look at how the components of the lymphatic system work together. It may also contain foreign invaders or damaged cells from the tissues. Lymph-The fluid within the lymphatic vessels which is rich in lymphocytes.They carry lymphocytes around the body and bring lymph to and from the lymph nodes, which are situated strategically along the lymph vessels. Lymphatic vessels-These thin-walled vessels are the “highway” of the lymphatic system.Other lymphoid organs/tissues-Bone marrow (a lymphoid tissue) and some lymphoid organs like the spleen and thymus are responsible for making lymphocytes.The other main components of the lymphatic system are: The lymphatic system is one of the chief ways dogs can fight infections and remove cellular debris from their blood. Your dog’s lymph nodes make up one segment of his or her lymphatic system, which is part of the immune system. white blood cells called lymphocytes) await instructions to go to battle against infectious agents or other foreign materials that don’t belong in a dog’s body. Inside these small, bean-shaped organs, immune system “soldiers” (i.e. In some ways, lymph nodes are the military training ground for the immune system. Lymph nodes are actually an integral part of your immune system, and the immune system of your canine companion too. These glands, called lymph nodes, don’t just swell up as an annoyance. If you’ve ever had a really bad cold or sinus infection, you may have experienced swollen glands around your throat.
