LYMPHEDEMA EXAM STUDY SET
Lymph is the name given to interstitial fluid that enters lymph vessels.
It contains:
Protein molecules
Water
Cellular Components
Fatty Acids
Function of the Lymphatic System - ANSWER The immune ANSWER protects
the body from infection and disease by producing, maintaining, and distributing
lymphocytes.
Facilitate fluid flow from tissues back into the bloodstream.
Lymphatic System Components: ANSWER Lymph vessels.
Lymph nodes
Spleen
Thymus gland
Tonsils
Peyers Patches
Lymphocytes
ANSWER: Capillaries are the superficial lymph vessels.
Pre-collectors
,Deep Lymph Vessels - Answer Collectors.
Trunks
Run parallel with deep arteries and veins.
Contains smooth muscle.
Valved (0.6-10 cm apart).
Collectors - ANSWER Divided by valves
Each segment is known as a lymphangion.
Lymph moves in one direction.
Anastomoses occur between collectors.
Lymphangion - Answer Teardrop-shaped segments
Smooth muscle layer.
Transport of lymph by intrinsic contractions
At rest, contractions average 6-10 per minute.
Can rise by tenfold with workout.
Contract segmentally.
Valved and semi-lunar
Valvular insufficiency causes reflux.
ANSWER: Muscle contraction is an extrinsic factor in lymph flow.
, Movement of body components and joints.
Arterial pulses
Respiration
External tissue compression: bandages and clothing.
ANSWER: Trunks drain all four quadrants of the body.
The thoracic duct penetrates the diaphragm; abdominal breathing creates a suction
force and facilitates lymph movement.
Cisterna Chyli holds up to a cup of fluid.
The right lymphatic duct drains the right upper quadrant.
Answer: 1-2 liters of lymph carried per day.
Lymph empties into the superior venous angles.
Watersheds - ANSWER Different anatomic regions of lymph drainage.
Anastomoses can occur when lymph is drained across a watershed.
Lymph Nodes - Answer: Small, kidney-shaped.
2-25mm in diameter.
600–700 in the body; 50% in the neck and trunk.
Often linked in a chain.
