Eating Alive-Part Two Flashcards
the lymphatic system is a network of what?
vessels, tissues, organs and cells
what does the lymphatic system include?
lymph vessels, lymph nodes, spleen, thymus and lymphocytes
what is lymph?
- is the watery substance that runs through the system
- comes from the Latin word lympha, meaning “clear water”
- it is slightly yellowish but clear in colour
- is any tissue or interstitial fluid that enters the lymph vessels
how is lymph formed?
when interstitial fluid is collected within the lymphatic system capillaries
where is the lymph then carried through?
the vessels and lymph nodes then ultimately carried to the subclavian vein and back into the blood
what is lymph similar to?
blood plasma, but contains more white blood cells
in the limbs, what is lymph rich in?
rich in protein, especially albumin
in the bone marrow, spleen and thymus, what does lymph have higher concentrations of?
higher concentrations of white blood cells
in the intestine, what is lymph contain?
contains fats absorbed during digestion
what does much of the toxicity get drained away through?
the lymphatic system
the lymph system is much larger than what and why?
much larger than the blood system as it is designed for waste drainage which is very important to cell health
what does the lymph system handle and can can it become overloaded?
handles only cell wastes, when the blood is also dumping toxins from the intestinal tract into the lymph system via the overloaded liver, the lymph system can start to overload too
what does the lymph system rely on?
relies on the less consistently used skeletal muscle contractions to squeeze the lymph along
what can contribute to lymph overload?
lack of exercise
sluggish lymph drainage is commonly felt where?
in the throat area because the lymph is closest to the skin surface there, but usually the overload is in the large intestine, with bad bacteria running rampant
what is the lymph also home of?
the immune system, thymus, bone marrow, and spleen (which are glands of the immune system)
which glands are fortresses in the lymph where the immune system attacks invaders and toxins?
- tonsils
- adenoids
- lymph nodes
what happens to large chunks of protein that is not digested well?
can be targeted as an immune system invader resulting in an overly reactive immune system and various allergies may occur
what do white blood cells do?
- float through the bloodstream eating and destroying anything they don’t like
- they are our bodies natural defenders
explain how WBCs multiply and change shape?
- can multiply in a day from a few to tens of thousands
- they change shape to slip through the gaps between cells so they can attack from all sides
there are trillions of WBCs including what?
- phagocytes
- B cells
- T cells
- macrophages
explain the thymus
- master gland of the immune system
- lies in the upper part of the chest
which WBC is the first to attack an invader and destroy it?
macrophages
what does macrophage activity stimulate?
the helper T cells which then stimulate the B cells and Killer T cells to help fight the invaders
