| 31. | They are used as antihypertensives because they block alpha-receptor-mediated vasoconstriction.
|
| 32. | Heat loss is inhibited by the intense vasoconstriction.
|
| 33. | Endothelin receptor activation mediates strong pulmonary vasoconstriction and positive inotropic effect on the heart.
|
| 34. | :: Well, I think it is to do with vasoconstriction and vasodilation.
|
| 35. | It also induces vascular vasoconstriction in the brain.
|
| 36. | Endothelial cells are responsible for releasing vasoconstriction and vasodilator factors, thus modifying tone.
|
| 37. | Therefore, nitric oxide is only produced during excessive vasoconstriction as opposed to hypoxia.
|
| 38. | Adaptation to cold reduces the extreme vasoconstriction which usually occurs with cold water immersion.
|
| 39. | Medications causing vasoconstriction, also known as vasoconstrictors, are one type of pupil dilation.
|
| 40. | A new phase of vasoconstriction follows the vasodilation, after which the process repeats itself.
