Lymphatic system
I. Introduction
● The lymphatic system is a component of the immune system that helps maintain
fluid balance and defends against disease.
● It is composed of the lymphatic vessels, lymph nodes, spleen, thymus, and
tonsils.
II. Lymphatic Vessels
● Lymphatic vessels are similar to blood vessels and transport lymph, a fluid that
contains waste products and excess fluid from the body.
● Lymphatic vessels converge in the lymph nodes, where waste products are
filtered and pathogens are identified.
III. Lymphatic Nodes
● Lymph nodes are small, bean-shaped structures that are located throughout the
body.
● They contain immune cells, such as lymphocytes, that help defend against
disease.
IV. Spleen
● The spleen is an organ located in the upper left side of the abdomen.
● It is responsible for filtering the blood and producing immune cells.
V. Thymus
● The thymus is a gland located in the chest that produces T-lymphocytes, a type of
immune cell.
● T-lymphocytes play a crucial role in defending against disease.
