anatomy quiz 5

vessels

pick up the extra tissue fluid that capillaries leave

lymph

the interstitial fluid carried by lymphatic

capillaries

absorb cell debris, pathogens, and cancer cells

trunks

include paired lumbar, bronchomediastinal, subclavian, jugular trunks, and one intestinal trunk

right lymphatic duct

joins with right subclavian vein and drains from the right upper extremity, head, neck, and thorax

thoracic duct

joins with left subclavian vein and drains from the rest of the body

cisterna chyli

enlarged portion of the thoracic duct that receives lymph from the digestive organs

immunocompetence

receptors on the cell surface recognize and bind to a specific antigen

self-tolerance

involves the cell’s ability to distinguish self from nonself

where are lymph nodes clustered in the human body

cervical, axillary, and inguinal

why does lymph need to flow slow

the slower it moves the more filtered it can get

what causes lymph to more slow

theres more afferent lymphatic vessels than efferent lymphatic vessels

structures of the lymph nodes

cortex, medulla, afferent lymphatic vessels, efferent lymphatic vessels, and germinal centers

afferent lymphatic vessels

theres 5 and it brings lymph in

efferent lymphatic vessels

theres 2 and it brings lymph out

why are the thymus and red bone marrow primary lymphoid organs

because of their roles in the production of B and T cells

red bone marrow

found in the epiphysis of long bones; where B cells mature

thymus

where T cells go for their maturation process

B cells

make antibodies

T cells

direct immunity

why are the tonsils, spleen, appendix, and peyer’s patches secondary lymph organs

because they filter lymph and blood

MALT

mucosa associated lymphoid tissue

tonsils structure- tonsillar crypts

lymphocytes

tonsils structure- germinal centers

trap bacteria and other foreign material

red pulp

red blood cells

white pulp

white blood cells

appendix

found in the right lower quadrant of abdomen

peyer’s patches

found in the ileum
