LYMPHATIC SYSTEM Flashcards
(30 cards)
What is the lymphatic system?
The Lymph System is:
- A network of tubes thorughout body
- Drains lymph fluid from tissues & empties it back into the blood stream
- To Heart - to Liver/ Empties through Stool AND
- To Heart - to Kineys/Empties through Urine.
SM TXT BK
The lymphatic system is a network of tubes throughout the body that drains fluid
(called lymph) from tissues and empties it back into the bloodstream. The main roles
of the lymphatic system include managing the fluid levels in the body, filtering out
bacteria, and housing types of white blood cells. Lymph is filtered through the spleen,
thymus and lymph nodes before being emptied into the blood.
What is the main role of the lymphatic system?
- The main roles of the lymphatic system include:
- Managing the fluid levels in the body
- Filtering out bacteria
- Housing types of white blood cells.
Lymph is filtered through the spleen,
thymus and lymph nodes before being emptied into the blood.
How is the lymph fluid filtered?
- Lymph is filtered through:
- The spleen,
- Thymus
- Lymph nodes before being emptied into the blood.
Where does filtered lymph fluid get emptied?
Lymph nodes before being emptied into the blood.
then heart
then elimination organs
liver - intestines - stool
kidneys - blader - urine
Where are Lymph nodes found?
Lymph nodes are found at various points around the body, including the throat, armpits, chest, abdomen and groin. All lie close to arteries.
Where is the only place that the Lymphatic Vessels do NOT criss-cross in the body?
The central nervous system. The lymph vessels don’t criss-cross the central nervous system.
SM TXT BK
- Lymphatic vessels; Lymphatic vessels criss-cross the entire body, except for the central nervous system.
- Some lymphatic vessels have valves (similar to the valves in veins), which stop the lymph from running back the wrong way.
What stops the lymph from running back the wrong way?
Lymphatic Vlaves (like the valves in the veins/trap doors). Some lymph vessels have valves.
-Some lymphatic vessels have valves (similar to the valves in veins), which stop the lymph from running back the wrong way.
Where is the Spleen located?
- Inside the abdomen, just under the diaphram.
SM TXT BK:
Spleen; The spleen is inside the abdomen, just under the diaphragm. This is one of the filtering organs of the blood. As well as removing microbes, the spleen also destroys old or damaged red blood cells.
What does the spleen do?
- One of the filtering organs of the blood.
- One of the organs that removes microbes.
- Destroys old or damaged red blood cells.
Where is the Thymus?
The is inside the ribcage/thoracic cage, just behind the breastbone.
SM TXT BK:
Thymus; The thymus is inside the ribcage, just behind the breastbone. This is another filtering organ of the blood, that contains many white blood cells called lymphocytes.
What does the thymus do?
- One of the filtering organs of the blood
- Contains white blood cells called lyphocytes (B-Cells and T-cells)
Where are Lymph Nodes found?
- All though the body
- Throat
- Armpits
- Chest
- Abdomen
- Groin
THEY ARE ALL CLOSE TO ARTERIES
SM TXT BK:
- Lymph nodes; Lymph nodes are found at various points around the body, includingthe throat, armpits, chest, abdomen and groin.
- All lie close to arteries.
- Bacteria picked up from the tissues by the lymph are trapped in the lymph node. White blood cells called lymphocytes can then attack and kill the bacteria.
- This is why your lymph nodes tend to swell if you have an infection. Viruses and cancer cells are also trapped by lymph nodes.
What does the Lyph do?
- Picks up bacteria, viruses, cancer cells from the tissues and traps them in the LYMPH NODE.
- White blood cells called LYMPHOCYTES kill the bacteria.
Where are Lymphocytes - (B-cells and T-cells) found?
- Lymph
- Blood
- Bone
- Bone marrow
- Thymus
- Spleen
- Tonsils
SM TXT BK:
Lymphocytes - B-cells and T-cells found in lymph, blood, bone, bone marrow, thymus, spleen, and tonsils, which produce antibodies, attacking and destroying antigens.
What do Lymphocytes - (B-cells and T-cell)?
- Produce antibodies to attack and destroy ANTIGENS.
What are Antigens?
GOOGLE: (a toxin or other foreign substance which induces an immune response in the body)
What are Tonsils?
SM TXT BK:
- Lyphoid tissue that protect from bacteria (nasal and oral cavity)
Tonsils - lymphoid tissue that protects against bacteria attempting to enter through the nasal and oral cavities.
Where are tonsils?
Tonsils are fleshy pads located at each side of the back of the throat.7 Nov 2020

What are the 4 organs of the lymphatic system?
SM - lymph, blood, bone, bone marrow, thymus, spleen, and tonsils,
bone marrow.
spleen.
thymus gland.
lymph nodes.
tonsils.
GOOGLE What are the 4 organs of the lymphatic system?
The lymphatic system consists of all lymphatic vessels and lymphoid organs. For example, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer’s patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs.30 Nov 2016

How does Breast Cancer treatment effect the Lymphatic System and what can patients do to reduce effects?
BREAST CANCER SUMMARY
- When they cut out breast cancer they cut out those lymph nodes underneath the arms to stop it spreading to other areas.
- Results in extreme swelling in the fingers, hands, arms; which means pain in their arms and around their armpit - because no lymph nodes in area to drain the toxins.
- NEED to MOVE ARMS to manually get that fluid moving through: Gently walking, moving in some way, elevating their arms above their head. Even a little bit dry brushing.
- So they can help that lymph drain out and it doesn’t pool down into their arms and hands.
- Lymph nodes and lymphatic organs filter the lymph fluit and eliminate harbful substance.
- Lymph Organs:
- Lymph nodes
- Spleen
- Thymus
- Lymphatic tissue in the small intestine (Peyer’s patches)
- Tonsils in throat (adenoid tonsils, palatine and tubal tonsils)
The lymph drains into lymphatic capillaries. The lymphatic capillaries conduct the fluid into larger lymphatic vessels, which carry it toward lymph nodes and lymphoid organs. The nodes and organs filter the lymph and eliminate harmful substances.
- Our bodies have 3 times more lymph fluid than blood
- No organ to pump it.
- The pumping action of deep breathing will help the lymphatic system transport the toxins into the blood before they are detoxified by the liver.
- Inversions and exercise help too
- Rebounding is the most effective way to pump lymph
- Hot water helps dilate the blood vessels, Cold water shrivels blood vessels. CREATES “PUMP” action that forces out the toxic fluids that have remained in the body.
What is Bone Marrow?
Bone marrow is a sponge-like tissue found inside the bones.
Bone marrow: This is the soft, spongy tissue in the center of certain bones, such as the hip bone and breastbone. White blood cells, red blood cells, and platelets are made in the bone marrow.
