lymphatic system

prevention of edema

The lymphatic system picks up fluid that builds up in capillaries

vitamins that are transported in the lymph

Actually Don’t Even Know

A - D - E - K

other system that lymphatic system is closely linked to

immune system

organs in lymphatic system

lymphatic tissues

lymphatic nodes

lymphatic vessels

spleen

tonsils

lymph is mostly made out of

water

what substances can be found in lymph

gases, ions, nutrients, enzymes, hormones, proteins

what body fluid does lymph resemble

plasma

where would you not find lymph capillaries

teeth, bones, nervous system

why does the brain not have lymph capillaires

brain has blood barriers so there no chance of fluid being in capillaries needed to be filtered out

lymphatic capillaries of digestive system

lacteals

type of cells lymph capillaries are made of

One layer of Epithelial cells

what vessel carries lymph in lymph capillaries

no vessel

mini-valves allow

fluid to enter and never exit lymph capillaries

lymph flows in what direction

towards the heart

parts of body that right lymphatic duct drains

right upper limb, right side of head, right thorax

parts of body that thoracic duct drain

entire body below diaphragm, left neck, left side of head, left upper limb

bulge around L2 on thoracic duct

cisterna cyli

where does right lymphatic duct drain drop lymph back int cardiovascular system

right subclavian vein

where does thoracic duct drain lymph back into the cardiovascular system

left subclavian vein

bulges along lymphatic vessels

lymphatic nodes

speed of lymph

slow

T-lymphocytes function

fight antigens directly and regulate immune response

B-lymphocytes function

produce antibody secreting plasma cells

where are B & T lymphocytes made

in red bone marrow

what is the function of macrophages

Phagocytes ( destroy pathogens and dead cells )

macrophages inside blood vessel

monocyte

where are dendritic cells found

skin

tissue reticular cells are made of

connective tissue

what lymph organ is not made of reticular tissue

thymus

difference between diffuse and follicular tissue

lymphocytes form follicles which have an organized pattern and contain capsules. diffuse tissue does not have this organized pattern and no capsules are present 

what occurs at germ center of a follicle

replication of lymphocytes

function of lymph nodes

filter and check for pathogens

what is lymphocyte capsule made out of 

dense fibrous tissue

what are trabeculae

these are connective tissue strands that separate lymph nodes into sections

outer part lymph node

Outer Cortex

middle part of lymph node

Inner Medulla

Immune cells that are found inside lymph cells

B-cells will be found in B-lymphocytes very organized and in capsules

T-cells will be found in T-lymphocytes unorganized and in medullary chords
