atherosclerosis

Question 1

promotes production of nitric oxide

Answer 1

normal and constant shear and pressure

Question 2

low shear can promote _____

Answer 2

artherosclerosis

Question 3

normal shear stimulates ______

Answer 3

nitric oxide production

Question 4

nitric oxide purpose

Answer 4

vasodilator/ helps regulate BP

Question 5

how does vascular branching promote atherosclerosis?

Answer 5

disrupts laminar flow resulting in areas of low shear
