What are Lymphatics? PART 2
Axillary lymph nodes
The axillary or armpit lymph nodes drain lymph from the arms, breast, chest wall and upper abdomen. They are large, vary from twenty to thirty in number, and may be arranged in the following groups: brachial lymph nodes (or "lateral", or "humeral")
Inguinal Lymph Nodes
The deep inguinal lymph nodes are located medial to the femoral vein and under the cribriform fascia. There are approximately 3 to 5 deep nodes. The superior-most node is located under the inguinal ligament and is called Cloquet's node.
Is the main vessel of the lymphatic system, passing upward in front of the spine and draining into the left innominate vein near the base of the neck.
The cisterna chyli (or cysterna chyli, and etymologically more correct, receptaculum chyli) is a dilated sac at the lower end of the thoracic duct into which lymph from the intestinal trunk and two lumbar lymphatic trunks flow.
Diseases of the Lymphatic system
Diseases and disorders of the lymphatic system are typically treated by immunologists. Vascular surgeons, dermatologists, oncologists and physiatrists also get involved in treatment of various lymphatic ailments. There are also lymphedema therapists who specialize in the manual drainage of the lymphatic system.
Lymphedema is a chronic swelling of the limbs caused by the accumulation of lymph fluid that occurs if the lymphatic system is damaged or not functioning properly. While the limbs are typically involved, the face, neck and abdomen may also be affected. Many develop the disorder following cancer therapy — particularly breast cancer where the lymph nodes under the arms are removed — recurrent infections, injuries or vascular surgery.
is a type of cancer that typically occurs when the white blood cells in the body become diseased or damaged.
Castleman disease is caused by benign tumors that affect the lymph nodes. While not specifically a cancer, it is a similar to a lymphoma and is often treated with chemotherapy.
is a disease involving multiple cysts or lesions formed from lymphatic vessels.
In elephantiasis, infection of the lymphatic vessels causes a thickening of the skin and enlargement of underlying tissues, especially in the legs and genitals.
Lymphangiosarcoma is a malignant soft-tissue tumor, whereas lymphangioma is a benign tumor occurring frequently in association with Turner syndrome.
Lymphangioleiomyomatosis is a benign tumor of the smooth muscles of the lymphatics in the lungs.
Lymphoid leukemias and lymphomas are called "leukemia" when in the blood or marrow and "lymphoma" when in lymphatic tissue.
Lymphoid leukemias and lymphomas
Lymphatic filiaris is a disease in which parasitic worms infiltrate the lymph system via the bite of a mosquito. About 120 million people worldwide are affected by this disease.
The lymphatic system is an important system in our body. It is one of the main sysems of our body. It is our body's defense system.
