WHAT ARE LYMPHATICS?
The lymphatic system is a vital system in the human body. Often considered a subsystem of the circulatory sysytem, the lymphatic system works to maintain fluid balance within our tissues. It also plays a very important role within the immune system by removing microorganisms and other pathogens from body tissues.
PATHOGENS: A pathogen is anything that causes a disease.
What structures make up the Lymphatic system?
The lymphatic system is composed of lymphatic vessels, lymph nodes, and organs such as, thymus, adenoids, and the largest lymphatic organ, the spleen.
There are more organs, like shown in the picture to the right.
The spleen is the largest lymphatic organ in the body . It is located in the upper left part of the abdomen under the ribcage, works as part of the lymphatic system to protect the body, clearing worn out red blood cells and other foreign bodies from the bloodstream to help fight off infection.
The palatine tonsils (what the term tonsils generally refer to) are two lymphatic tissue masses. There is one located on each side of the oral pharynx, in the back of the throat.
A lymphoid organ situated in the neck of vertebrates that produces T cells for the immune system. The human thymus becomes much smaller at the approach of puberty.
RIGHT LYMPHATIC DUCT
The right lymphatic duct is the short vessel that receives lymph from the right side of the head, neck, and thorax, the right arm, right lung, right side of the heart, and convex surface of the liver and that discharges it into the right subclavian vein at its junction with the right internal jugular vein.
CERVICAL LYMPH NODES
Cervical lymph nodes are lymph nodes found in the neck. There are enlargements possible. Lymph nodes in the head and neck form groups. These groups are responsible for draining lymphatic fluid from different areas (Regions) in the head and neck.
