A) Lymph vessels are the thin walled vessels. They are structured like blood vessels. They carry lymph when blood vessels carry blood. Lymph vessels are complementary to the cardiovascular system. Lymph vessels are present all around the human body. They have many divisions and circulations. Each of them carry lymph to the whole body parts. They are called in several names according to their site and function. The lymph vessels are avoiding the waste and toxic materials out of the body through lymph. Lumbar, jugular, subclavian and bronchomediastinal are the major lymph vessels present. Lymph nodes can be feel on our arm pit, neck etc..

B) lymph is moved through our body. The one way journey starts from intestinal space to the subscavian veins at the base of the neck. The movements of lymph is depend on the motion of muscle and joint pumps. Lymph are transported from lymphatic capillaries to the lymphatic vessels and they are dump in the circulatory system via lymphatic ducts. Specifically subscavian vein. When the lymph leaks they are intestinal fluids and lymph vessels collect this fluids and return into the blood stream.

C) A small bean shaped structure that are located on the arm pit and the base of the neck. Lymph nodes are filtering the material travel through the lyphatic circulation. There are 501 of lymph nodes present in the body. They carries white blood cells that prevents infection. They are connected with many lymphatic vessels. They are sometimes infected by microorganisms and cause swelling.

D) As i i mentioned, the major function of the lymphatic system is immunity. It is the first line defence against the diseases.

1. They remove intestinal fluids from the body tissues.

2. Removal of toxic and waste materials through lymph fluids.

3. Fatty acids and fats are absorbed and transported.

4. Fluid homeostasis
