MICROANATOMY

Detailed explanation-1: -The lymph nodes filter out harmful substances and waste products. They also contain immune cells called lymphocytes that destroy cancer cells and bacteria. The filtered fluid is then returned to the blood circulation. If you have an infection or cancer, a lymph node may become swollen.

Detailed explanation-2: -The thymus is a specialized organ of the immune system, located between the breast bone and heart. It produces lymphocytes, is important for T cell maturation (T for thymus-derived).

Detailed explanation-3: -It produces and releases lymphocytes (white blood cells) and other immune cells that monitor and then destroy the foreign invaders-such as bacteria, viruses, parasites and fungi-that may enter your body.

Detailed explanation-4: -Inside the lymph nodes are white blood cells, also called lymphocytes. These white blood cells attack and break down bacteria, viruses, damaged cells or cancer cells. The lymph fluid carries the waste products and destroyed bacteria back into the bloodstream. The liver or kidneys then remove these from the blood.
