Blood and Lymphatic System Terms

The flow of lymph from an area of tissue into a particular lymph node.

The use of dyes and radioactive substances to identify lymph nodes that may contain tumor cells.

The plumbing that fails in lymphedema and the route many cancers travel out of an organ, known equally as a lymphatic vessel.

Taking out lymph nodes to learn whether cancer has reached them, an operation now used far more sparingly than it once was.

Lymphadenopathy is enlargement of one or more lymph nodes, a common finding that can reflect infection, inflammation, or, less often, malignancy.

An x-ray of the lymphatic system.

An x-ray study of the lymphatic system.

A type of cancer that begins in the cells that line lymph vessels.

A group of lymph nodes that receives and filters lymph that flows from a certain area of the body.

Clear in an arm, milky after a fatty meal: how it looks depends entirely on which tissue it has just drained.

The use of dyes and radioactive substances to identify lymph nodes that may contain tumor cells.

The lymphatic system is a network of vessels and organs that drains excess fluid from tissue and supports immune defense.

Half of the circulation runs one way only: these tubes gather the fluid that leaks out of capillaries and hand it back to the blood.

A condition in which extra lymph fluid builds up in tissues and causes swelling.

One word covering two quite different cells: an immature precursor in the marrow, and a mature cell swollen by activation.

A word about appearance under the microscope that decides which disease a cancer of lymphocytes is, and how fast it must be treated.

An aggressive (fast-growing) type of non-Hodgkin lymphoma in which too many lymphoblasts (immature white blood cells) are found in the lymph nodes and the thymus gland.

These are the cells that remember, which is why a second encounter with the same organism is dealt with far faster than the first.

Lymphocytic describes anything relating to lymphocytes, the white blood cells central to the body's immune response.

One name covers two diseases that differ in nearly everything except the cell they come from: pace, age and urgency.
