APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The lymph nodes and other lymphatic structures like the spleen and thymus hold special white blood cells called lymphocytes.

Detailed explanation-2: -Lymph contains a variety of substances, including proteins, salts, glucose, fats, water, and white blood cells. Lymphatic fluid is also densely populated by the WBCs. The lymph does not normally contain any red blood cells.

Detailed explanation-3: -The blood cells are red because of the interaction between iron and oxygen. So the colour of blood is due to the presence of haemoglobin in RBCS since RBCs are absent in lymph it is colourless.

Detailed explanation-4: -Lymph nodes filter substances that travel through the lymphatic fluid, and they contain lymphocytes (white blood cells) that help the body fight infection and disease. There are hundreds of lymph nodes found throughout the body. They are connected to one another by lymph vessels.
