What is the term that means tumor of lymphatic tissue?

Lymphoma. A general term form for malignant disease of the lymphatic tissue characterized by abnormal, uncontrolled cell growth. There are a number of types of lymphoma, including Hodgkin Lymphoma, with most other types classed together as Non-Hodgkin Lymphoma. Hodgkin Lymphoma.

Lymphatic tissue is rich in lymphocytes (and accessory cells such as macrophages and reticular cells). The lymphatic tissue includes the lymph nodes, spleen, tonsils, adenoids and the thymus (an organ in the chest that is particularly large during infancy). Thus, the bone marrow is also a tissue.

Subsequently, question is, what are the lymphatic organs and tissues? In addition to lymph nodes, the lymphoid organs and tissues include the spleen, thymus, tonsils, and other lymphoid tissues scattered throughout the body. The lymphoid organs house phagocytic cells and lymphocytes, which play essential roles in the body’s defense mechanisms and its resistance to disease.

Hemangioma. A hemangioma is a benign (noncancerous) tumor made up of blood vessels. There are many types of hemangiomas, and they can occur throughout the body, including in skin, muscle, bone, and internal organs.

What are the 6 lymphatic organs?

What is the largest lymph node in our body?

spleen

Where is lymph tissue located?

The most diffuse lymphoid tissue is found in the loose connective-tissue spaces beneath most wet epithelial membranes, such as those that line the gastrointestinal tract and the respiratory system.

What is lymphatic tissue composed of?

It consists of connective tissue formed of reticular fibers, with various types of leukocytes (white blood cells), mostly lymphocytes enmeshed in it, through which the lymph passes. Regions of the lymphoid tissue that are densely packed with lymphocytes are known as lymphoid follicles.

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 organ is the largest mass of lymphatic tissue?

The spleen is the largest mass of lymphatic tissue in the body. It consists of cells and vessels contained within a capsule lined by mesothelium, from which trabecula enter the splenic parenchyma.

Where are Peyer’s patches located?

Peyer’s Patches: These are lymphoid follicles similar in many ways to lymph nodes, located in the mucosa and extending into the submucosa of the small intestine, especially the ileum. In adults, B lymphocytes predominate in Peyer’s patches. Smaller lymphoid nodules can be found throughout the intestinal tract.

What are the 4 main functions of the lymphatic system?

Functions of the Lymphatic System The removal of excess fluids from body tissues. Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system. Production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells).

What are lymph vessels called?

Function of the Lymphatic System Mingled among the blood capillaries throughout your body is another network of tiny, thin-walled vessels called lymphatic capillaries. Lymphatic capillaries are designed to pick up the fluid that leaks into your tissues from your bloodstream and return it to your circulatory system.

Where do lymph vessels begin?

The efferent lymphatic vessel commences from the lymph sinuses of the medullary portion of the lymph nodes and leave the lymph nodes at the hilum, either to veins or greater nodes. It carries filtered lymph out of the node. Efferent lymphatic vessels are also found in the thymus and spleen.

Are lymph vessels open ended?

Lymph or lymphatic capillaries are tiny thin-walled vessels, closed at one end and located in the spaces between cells throughout the body, except in the central nervous system and non-vascular tissues.

What are lymph vessels for?

Lymphatic Vessels. Lymphatic vessels are thin-walled, endothelial-lined channels that originate near the capillary beds and serve as a drainage system for returning interstitial tissue fluid and inflammatory cells to the blood.

What is the medical term for tumor?

tumor (TOO-mer) An abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Tumors may be benign (not cancer), or malignant (cancer). Also called neoplasm.

What is the medical term for tumor of a gland?

A malignant tumor that is derived from glandular tissue or one where tumor cells form glandular-looking structures is called an adenocarcinoma, with carcin- easily enough suggesting cancer, and where -oma means tumor. So, we literally get a cancerous tumor of the glands.
