|
LYMPHOMA
|
cancer in the lymph system
|
|
|
HODGEKINS DISEASE
|
cancer of the lymph system
|
|
|
MEDIASTINUM
|
area between lungs - lots of nodes, can have cancer
|
|
|
WHAT IS THE MOST COMMON KIND OF BREAST CANCER? WHAT IS DONE?
|
ductal carcinoma (in ducts)
- removal of tumor, some breast tissue & axillary lymph nodes - wear compression sleeve b/c of edema in arms |
|
|
FUNCTIONS OF THE LYMPHATIC SYSTEM (3)
|
- fluid recovery
- immunity - lipid absorption |
|
|
WHAT IS THE ONLY LYMPHATIC VESSEL THAT IS REALLY VISIBLE?
|
thoracic duct
|
|
|
WHAT IS THE MAIN DIFFERENCE BETWEEN LYMPH VESSELS AND BLOOD VESSELS?
|
lymph vessels dead-end because it is a one-way (draining) system
|
|
|
WHAT HAPPENS WITH THE VALVELIKE FLAPS ON THE LYMPH CAPILLARIES WHEN FLUID PRESSURE (around tissue) IS HIGH?
|
the flaps open (tethers open them), fluid flows into the lymph vessel
|
|
|
WHAT HAPPENS WITH THE VALVLIKE FLAPS ON THE LYMPH CAPILLARIES WHEN CAPILLARY PRESSURE IS HIGH?
|
the flaps close because the lymph system is overwhelmed/backed up. This leads to edema
|
|
|
LYMPHANGITIS
|
infection in the lymph system - slow red streaks
- could lead to blood poisoning |
|
|
LARGER LYMPH VESSELS HAVE...
|
valves
some smooth muscle |
|
|
3 THINGS THAT HELP WITH MOVEMENT OF LYMPH
|
1. gravity
2. muscle contraction 3. breathing (b/c it increases abdominal pressure) |
|
|
CISTERNA CHYLI
|
origin/beginning of thoracic duct
|
|
|
THE THORACIC DUCT LEADS TO THE....
|
left subclavian vein
|
|
|
THE RIGHT LYMPHATIC DUCT LEADS TO THE...
|
right subclavian vein
|
|
|
THE RIGHT ARM, RIGHT CHEST, RIGHT SIDE OF THE HEAD DRAIN INTO THE RIGHT LYMPHATIC DUCT. WHAT DOES THE REST OF THE BODY DRAIN INTO?
|
thoracic duct
|
|
|
LYMPHATIC ORGANS - definition and types
|
Lymphatic tissue with capsule
- red bone marrow - thymus - lymph nodes** (only one having lymphatic fluid brought to it) - tonsils** |
|
|
WHY DOES A LYMPH NODE HAVE GOOD IMMUNOSURVEILANCE?
|
many afferent lymph vessels (coming in), and only one efferent lymph vessel going out so everything gets seen
|
|
|
WHAT HAPPENS TO YOUR LYMPH NODES WHEN YOU ARE FIGHTING IN INFECTION? HOW IS IT DIFFERENT FROM WHEN A NODE HAS CANCER CELLS?
|
they feel swollen and tender.
Different than when there's cancer because cancer makes the nodes swell but NOT TENDER |
|
|
LYMPH NODULE
|
collection of lymphocytes (when surrounded by a capsule, they are collectively a lymph node)
|
|
|
WHAT ARE THE THREE TYPES OF LYMPH NODES (regional/groups)
|
cervical, axillary, and inguinal lymph nodes
|
|
|
LYMPHATIC TISSUES
|
aggregates of lymphocytes (immune cells) along digestive, urinary tracts, etc. - mucosa-assoc.-lymphatic-tissue (MALT)
|
|
|
PEYER PATCHES
|
lymph nodules along small intestine (ileum) - no lymphatic vessels involved. If a pathogen is passed from the lumen to the lymphatic nodule, there will be an immune response there
|
|
|
3 TYPES OF TONSILS
|
- pharyngeal tonsil (airborne particles from nose) > pharynx
- palantine tonsils under palate - pathogens from mouth - lingual tonsil under tongue - pathogens in mouth |
|
|
WHAT ARE THE STRUCTURES THAT SURROUND THE PALATINE TONSILS?
|
- palatoglossal arch (anterior - in between palate and tongue)
- palatopharyngeal arch (posterior - btwn palate and pharynx) |
|
|
SWOLLEN TONSILS - 2 types
|
palatine tonsils
- bacterial - dots on tonsils & gray, furry tongue - viral - swollen but no dots > just gargle salt water |
