Introduction to the Lymphatic System The lymphatic system consists of a network of lymphatic vessels, lymphatic tissues, lymph nodes and other lymphoid organs The lymphatic vessels carry lymph which is a fluid that consists of water and a small amount of dissolved proteins. David Terfera, PhD, teaches biomedical sciences at the University of Bridgeport College of Naturopathic Medicine. The lymphatic system includes a network of vessels, ducts, and nodes, as well as organs and diffuse tissue that support the circulatory system. Lymphnodes. It removes old or damaged red blood cells, which are phagocytized by macrophages. Infected tonsils are usually red and swollen, or they may have a whitish coating on them. The major parts of the lymph tissue are located in the: bone marrow; spleen; thymus gland; tonsils; The heart, lungs, intestines, liver, and skin also contain lymphatic tissue. Your lymphatic system actually has many functions. Its key functions include: The lymphatic system consists of many parts. The result is abdominal pain and tenderness over the appendix. Maintain a healthy lifestyle that includes regular exercise and a healthy diet. The lymphatic system parallels the cardiovascular system (see the images below). The lymphatic system is comprised of fine vessels. Like the thymus, the spleen houses and aids in the maturation of lymphocytes. The swelling of lymph nodes during an infection and the transport of lymphocytes via the lymphatic vessels are but two examples of the many connections between these critical organ systems. The primary lymphoid organs are the red bone marrow, in which blood and immune cells are produced, and the thymus, where T-lymphocytes mature. Some of the key areas in which the lymphatic system supports the body are the following: Immune System: The lymphatic system is best known for its defense against infection and disease. The swelling of lymph nodes during an infection and the transport of lymphocytes via the lymphatic vessels are but two examples of the many connections between these critical organ systems. These tests allow your doctor to see blockages in your lymphatic system. Search from Lymphatic System Organs stock photos, pictures and royalty-free images from iStock.

Primary lymphoid organs include the thymus, bone marrow, fetal liver, and, in birds, a structure called the bursa of Fabricius. Lymphatic System and its Organs 1. C. The lymphatic system regulates blood pressure through the renin-angiotensin-aldosterone mechanism. Lymphatic System: Organs. It’s located in the lower-right area of the abdomen. Lymphocytes destroy pathogens and dead cells in the blood. A system of vessels in the vertebrate body, beginning in a network of exceedingly thin-walled capillaries in almost all the organs and tissues except the brain and bones. 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. Lamina propria lymphocytes: This type of GALT is located in the mucosa of the small intestine. The remaining three liters seep through the capillaries and into your body’s tissues. Lymphatic system. The exception is thymus where lymphatic cells are embedded in reticular epithelium, which associates with organ development (see below). The lymphatic system is a network of tissues, vessels and organs that work together to move a colorless, watery fluid called lymph back into your circulatory system (your bloodstream). in alimentary canal or respiratory tract – mucosa-associated lymphoid tissue (MALT)).

Functions of lymphatic system: 1. transport lymph fluid to blood vessels 2. protect body from foreign … The three lymphatic organs are discussed in the following sections. The lymphatic system makes blood cells through a process known as hematopoiesis. The spleen’s main function is to filter the blood.
