hemostasis Flashcards
what is the normal physiology ?
its the since about heathy body function
what is the physiology ?
its the study about body function regulation
what is the regulation mean ?
its mean the mechanism or increasing or decreasing i the actively of tissue , organs , or organ system in order to achieve a certain result
what’s the physiologist interested in ?
they are interested in
1- mechanism of body function regulation
ex / how the muscles are contract or how gastric juies is secrets , or ow urin formation happened
2- with what a propose of regulatory process take place
ex/ what for stimulations of cardiac activity happens in stressful situation
and what about breathing decreasing at rest time
what is the function of the hemostats miniating
its to hold the internal environment in the holistic organism
explain the concept of homeostasis
the concept of hemostasis or to be more precisely
dynamic homeostasis its relative dynamic constancy of the internal environment
and of some physiological function of humane body and animals
ex for these function / blood circulation , metabolism thermoregulation .
what is the homeostasis parameters
its individual process each of which can be charectrazid by its own
ex / blood PH , calcium concentration in interstitial fluid or blood
glycose level
what is the homeostasis ?
is set of response that ensure maintaining constancy of the internal environment of the body , in condition of ever changing states of external environment
ex for homeostasis /
even if the body in cold the temperature should remine 36.6 C
what is the homeostatic constants may flucatet
that’s is change their value in different condition at different kind of influence
, by the impact of external environment
ex / you ate a lot of sugar , glycose concentration in the blood increased
,ex2 / you start running the respiratory rate increased
what is the homeostatic indices ?
its the make of rigid and non-rigid
what is the rigid ?
its Constance capable of changing their value within small limits
ex / blood PH 7.35 -7.43
what is the non-rigid ?
its Constance capable of changing their value about half or even serval times
Ex / glycose in the blood 3.3 -6.6
mechanism of maintaining homeostasis ( types )
its two type
- 1- humoral regulation
- 2- nervous regulation
what is the humoral regulation ?
is regulation by secretion of substance into the body fluid mediums ( blood , lymph, interstitial fluid
ex /adrenalin though the blood stimulate heart activity
what is the nervous regulation ?
its carried out though central nervous system which implements the reflexes
ex of reflexes / arm withdrawal upon finger prick
head turning towered upon light
