The lymphoid organs assist the lymphatic system. They include the thymus, spleen, tonsils, and appendix, along with some special tissue in the gut: The thymus: The thymus is located in the thoracic cavity, just under the neck. It’s made up of two lobes of lymphoid tissue.
What are the two types of lymphatic tissues found in the thymus lobules?
The thymus tissue is distinguishable into an outer zone, the cortex, and an inner zone, the medulla. The organ is composed principally of two types of cells, called, respectively, lymphocytes (see lymphocyte) and reticular cells.
What are the 3 main parts of the lymphatic system?
The major components of the lymphatic system include lymph, lymphatic vessels, and lymphatic organs that contain lymphoid tissues.
- Lymphatic Vessels. Lymphatic vessels are structures that absorb fluid that diffuses from blood vessel capillaries into surrounding tissues.
- Lymph Nodes.
- Bone Marrow.
What is the largest lymph node in your body?
Why are lymph nodes the only lymphatic organs that can filter the lymph?
Inside the lymph nodes, lymphocytes called T-cells and B-cells help the body fight infection. Lymphatic tissue is also scattered throughout the body in different major organs and in and around the gastrointestinal tract.
What are the main organs in the lymphatic system?

How do you know if your lymphatic system is blocked?
Five Signs Your Lymphatic System is Blocked. Bloating in the lower abdominal region can denote a blockage of your lymph system. The primary way that the lymph system moves toxins is through lymph fluid. If you notice consistent bloating, it could mean you have a lymphatic blockage.

What type of tissue is in the thymus gland?
Epithelial tissues and lymphatic tissues containing dendritic cells and macrophages make up the majority of both regions of the thymus. The function of the thymus is to receive immature T cells that are produced in the red bone marrow and train them into functional, mature T cells that attack only foreign cells.
What type of tissue is lymphoid tissue?
Lymphoid tissue. Lymphoid tissue, cells and organs that make up the lymphatic system, such as white blood cells (leukocytes), bone marrow, and the thymus, spleen, and lymph nodes.
Is the thymus a lymphoid organ?
The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells mature. The thymus is composed of two identical lobes and is located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum.
What are the 4 main functions of the lymphatic system?
The lymphatic system has multiple interrelated functions: It is responsible for the removal of interstitial fluid from tissues. It absorbs and transports fatty acids and fats as chyle from the digestive system. It transports white blood cells to and from the lymph nodes into the bones.
What happens when your lymphatic system malfunctions?
The lymphatic system clears away infection and keeps your body fluids in balance. If it’s not working properly, fluid builds in your tissues and causes swelling, called lymphedema. Other lymphatic system problems can include infections, blockage, and cancer.
What diseases affect the lymphatic system?
Lymphoma. Cancer that starts in the lymphatic system is known as lymphoma. It is the most serious lymphatic disease. Hodgkin lymphoma affects a specific type of white blood cell known as Reed-Sternberg cells.
What are the signs that you have a cancerous lymph node?
