Lymphatic system Flashcards
What is the role of the Lymphatic system
The lymphatic system is the drainage system of the body
What is the role of the lymph?
(watery fluid collected from tissues)
This fluid contains antibodies and lymphocytes. It also contains bacteria that will get filtered out by the lymphatic system. The lymph is transported by the nodes and vessels.
What is the role of the lymphocytes?
Lymphocytes are a type of white blood cell. There are 2 types, B cells and T cells. B cells produce the antibodies which are important for killing pathogens. T cells identify infected cells and get rid of them.
What is the role of the Lymphatic vessels?
Lymphatic vessels are similar to blood vessels. They carry the lymph around the body. They are very thin.
What is the role of the Lymph nodes?
Lymph nodes are important because they filter out the harmful substances. They contain white blood cells to fight pathogens in the lymph fluid. They are small lumps of tissue.
What is the role of tonsils
They are located in the throat and palate and they stop pathogens from entering the body. They contain white blood cells.
What is the role of the spleen?
It filters the blood and removes the damaged red blood cells and stores the iron.
It also stores blood and will release the blood into the circulatory system in an emergency such as extreme blood loss.
What is the role of Thymus Gland?
Produces progenitor cells which will mature into T-cells. The T-cells will destroy infected cells or cancerous cells.
