correctly answered to pass
1. what is the largest endocrine gland endothelium

2. what are 3 vasodilators nitric oxide, prostacyclin,
endothe- lium derived
hyperpolarization fac- tors
(EDH)

3. this vasodilator is involved in Nitric oxide
maintenance of basal vasodilator tone
of blood vessels, it re- duces platelet and
monocyte sickness, oxidation of LDL and
release of superoxide free radicals
prostacyclin
4. this vasodilator is synthesized from
arachidonic acid...mainly involve PGI2 and
PGE2...relaxes the vascular smooth
muscle...helps in release of NO from
endothelium

5. this vasodilator relaxes smooth muscle endothelium derived
hyperpolar-
ization factor

6. what are three vasoconstrictors endothelin-1, prostaglandins,
reac- tive oxygen species

7. endothelin-1 exerts vasoconstrictor vascular smooth muscle
actions through stimulation of ETA
receptors in


8. T/F: prostaglandins involve PGH2, is a true
vasocon- strictor, and is precursor for
prostanoids

9. how do ROS lead to vasoconstriction inhibit release of NO

10. which COX enzyme stimulates COX-1
