The lymphatic system consists of all the following EXCEPT

Blood

The activity of the T lymphocytes brings about

Cell mediated immunity

Once they have reacted with antigen molecules the B lymphocytes of the immune system

Convert into plasma cells to secrete antibodies

Lymph nodes may be located in the human body in the tissue of the

Groin and neck

Lymphatic capillaries resemble blood capillaries because lymphatic capillaries:

Have a lining of endothelium

During fetal development the immune system eliminates lymphocytes displaying antibodies against self antigens also known as

The lymphatic vessels that are rich in fat are known as

Lacteals

The T lymphocytes & B lymphocytes are the major cells of The

Lymph nodes

The lymphatic system consists of

Lymph, lymphatic vessels and lymph nodes

The cells that set the immune process into motion are phagocytic cells known as

Macrophages

The fluid that passes through the lymphatic vessels

Moves in a single towards the heart

The nodules of lymphoid tissue found in the wall of the intestinal tract known as

Peyer's patches

The movement of fluid through the lymphatic vessel is assisted by

Pressure from contracting skeletal muscles

All the lymphocytes of the immune system arise from

Primitive cells in the bone marrow

Which of the following is not likely to be found in the lymph

Red blood cell

All the following are important functions of the lymph nodes EXCEPT

They function in the production of neutrophils eosinophils and basophils

Antibody molecules neutralize invading microorganisms by all the following methods except

They robbed Michael organisms of the oxygen they need for metabolism

T-lymphocytes are so named because they mature in the

Thymus
