endocrine |
secreted into interstitial fluid & absorbed into blood stream |
|
|
autocrine |
secreted by cell, and bind to the same cell |
|
|
paracrine |
secreted by cell and works on a nearby cell |
|
|
lipid soluble hormones include: |
steroids, thyroid hormones, NO *these bind to receptors in cytoplasm or nucleus of cell |
|
|
water soluble hormones include: |

|
|
what does GhRH release? |
GH (promotes growth) |
|
|
what does TRH release? |
TSH (stimulates thyroid to release T3 T4) |
|
|
what does PRH release? |
PRL (breast growth/mammary production) |
|
|
what does GnRH release? |
FSH (ovaries=oocytes/testes=sperm) LH (ovaries=ovulation, progesterone, estrogen/testes=testosterone) |
|
|
what does GRH release? |
ACTH (adrenal gland- glucocortoroid, mineralocortocoid, androgens) MSH (melanin) |
|
|
hypovolumetric shock |
decrease in blood volume |
|
|
cardiogenic shock |
poor heart function |
|
|
vascular shock |
excessive vasodilation |
|
|
obstructive shock |
when blood flow is obstructed |
|
|
order of cardiac contraction |
atria contract> isovol contract> ventricle ejects> isovol relaxes> ventricles fill> atria contract |
|
|
systole |
contract/release |
|
|
diastole |
filling |
|
|
order of cardiac action potential |
SA node> AV node> bundle of his> purkinje fibers *SA node = fast AV node = slow |
|
|
blood flow |
arteries> arterioles> meta-arterioles> pre-cap. sphincter> capillaries> post-cap. venule> venule> veins |
|
|
how to fix damaged bv |
vascular contraction, platelet plug, clotting (prothrombin turns to thrombin) |
|
|
