• stimulates the kidney to conserve water
• responds to an increase in blood osmolarity or decrease in blood volume
• osmolarity- concentration of bcells
• causes vasoconstriction
• result in increase of bp

• released by atria
• lowers bp
• vasodaiation
• increases salt (via osmosis)
• antagonist to adh and aldostrone

• paricine
• vasodialtion
• effects are short lived
• cause muscle to relax
• released by endothelial cells in response to hig bp flow
• may be a major factor in affecting bp on a local level

• draining excess interstital fluid
• transporting dietary lipid and lipid soulable vitamins a,d,e,k to blood
• facilitating the immune response
• procducem maintaing and distrubute lymphocytes

• bacteria
• viruses
• funis
• anything forgien

• fluid that is present in the lympatic sxystem and is identical to the composition of intersitial fluid
• formed by capillar filtration

• resemble veins. but have thinner walls and many more valves
• under lower pressure then the cardiovasular system move viat contraction of skeletal muscle

• smallest vessel
• blind ended do not connect to anything (on way road not connected to nothing)
• start wher cardiovasular capillary are
• slightly bigger then cardiovascular capillaries (blood capillaries)
• greater permeablility then blood capilaries
• lymph have overlap
• located throghout teh body except avascular tissue(cartilage), spleen. redbone marrow, and cns
• structure premits fluid to enter, but not leave

• lymphatic capillaries associated with the small intestines
• responsible for absorption of nutrients

• composstion of fluid in lacteals
• milky color dute to excess fats

• smaller then veins
• valves

• vessels leaving chains of nodes unite to form a lymphatic trunk
• these passes their fluid into ducts which return flused to the venous system

• right lymphatic duct
• the rest of the body
• fluid from both legs and left side of arm head

• all right arm
• 1st quarderent
• right side of head
• upper right portion of the body

• small bean shped structure
• approximatley 600
• scattered throughout body, but concetrations in neck, groin, and arm pit areas
• function to filter lymph
• contain macrophages. concetrations of lymphocyte

• capsule- the foundation of structure
• trabeculae- not hollow have twho halves
• subcapular space
• reticular fibers and dendritic cells form a mesh filter

• outer layer- lymphatic nodules (bcells)
• inner- tcells

• bcell and macrophages
• medullary cords

• is one way
• enters afferent capillaries(move in)
• flows through sereis of compartments where it is flitered
• flows out through 1-2 efferent vessels (moving out)
• lymph typically passes from one node to another within a chain

• endocrine gland
• produces hormones that directly production of lymphocytes
• primary lympathic organ
• produces hormone necessary from production of lymphoclytes
• mature site for tcells
• tcells- produce in bone marrow but mature in thymus gland
• large in infants and atrophies with age
• atrophies- reduce, get smaller, not as active

• also primary lymphatic organ
• form lymphoctyes

largest in mass of lymphatic tissue, but is not a primary lymphatic organ (sinusoide capillaries)

• white pulp- lymphatic tissue
• red pulp- region responsible for removal of rbcs
• storage of platelets and rbc
• hempoises in infants

• concetration of lymphatic tissue not sourrounded by a capsule
• associated with mucosal membrane
• mucosa- associated lymphatic tissue (malt)

assocaited with gi tracts

• tcells- originated in red bone marrow/ thymus dependent - fully mature in thymus gland
• bcells-produce antibodies/ bone marrow derived, mature in redbone marrow
• natural killer cells- ability to recognize pathogens ingeneral and attact them (nonspecifice) attact varity of pathogens
