CVS: capillaries and lymph Flashcards
what are three ways in which the cardiac system responds to exercise
how does the body increase symp activity during exercise
how does blood flow change during exercise
why do capillaries have the lowest velocity of blood
explain why velocity is inversely prop to area
what happens at capillaries
which tissues will haver denser capillaries? why?
where are continuous capillaries found
what is the difference in properties between cont and fenestrated capillaries
where are fenestrated capillaries found
how are substances exchanged between plasma and interstit fluid
how do small molecules get exchanged? how do larger molecules get exchanged?
describe difference between para and trans cellular transport
what moves using transcytosis
what moves using diffusion
how do lipid solubule substances move through capillaries
how do lipid insoluble substances move through capillaries
co2 and o2 are examples of
h2o, na, cl are examples of
what do conc gradients do to diffusion? why?
how does size affect movement through pores
how wide are intercellular slit pores
different in cap perm between water and albumin
what is bulk flow
what is the dif between absorption and filtration
what is cap hydrostatic pressure
what is interstitial fluid pressure
what is plasma colloid osmotic pressure
what is interstitial fluid colloid pressure
how do the four capillary pressures interact with eachother? what impact to they have on absorption and filtration?
how is bulk flow regulated? what does this mean?
what is net filtration pressure
how do you calculate net pressure? how do you interpret this value?
what is the lymphatic system? how does it interact with capillaries?
what are the roles of the lymphatic system?
why do we need the lymphatic system (what does it provide for fluids?)
what is edema? when does it happen?
what is lymph
where does lymph drain into? why
when does edema happen? where can it happen?
does edema happen with high or low cap. pressure?
what is elephantis
why does elephantis occur
how can obstruction lead to edema?
what is ascites
why does ascites occur
what happens in liver cirrhosis
why does liver cirrhosis occur
