Lymphatic System

The lymphatic system is a part of your body that works closely with the immune system to protect you from bacteria, viruses, and other harmful invaders.

It is made up of lymph, lymph nodes, lymph vessels, and organs like the spleen, tonsils, and thymus gland.

Let’s begin with lymph, a yellowish fluid that leaks from blood vessels into the spaces between cells and collects germs and waste.

This fluid is carried by tiny lymph vessels through your body like a secret highway.

Along the way, the lymph passes through lymph nodes, which act like security checkpoints.

These nodes contain special cells called lymphocytes that trap and destroy harmful pathogens. Different types of lymphocytes, such as B cells and T cells, help fight infections.

B cells originate in the bone marrow and help make antibodies to attack invaders. T cells are also produced in the bone marrow but mature in the thymus gland, where they learn to identify and eliminate infected or abnormal cells.

After this filtering, the lymphatic system returns the cleansed fluid to the bloodstream, maintaining circulation.
