Biology for AP Courses 2022-06-09T00:00:00Z For example, after a large meal, most of the blood is diverted to the stomach by vasodilation of vessels of the digestive system and vasoconstriction of other vessels. Biology for AP Courses 2022-06-09T00:00:00Z Reduction of sympathetic stimulation results in vasodilation and increased blood flow through the kidneys during resting conditions. Anatomy and Physiology 2013-06-19T00:00:00Z Sympathetic stimulation of the peripheral arterioles will also decrease, resulting in vasodilation. Anatomy and Physiology 2013-06-19T00:00:00Z In diseases of the heart the sudden vasodilation caused by amyl nitrite inhalations is indicated only in angina pectoris. Disturbances of the Heart As vasodilation occurs in selected vessels, resistance drops and more blood rushes into the organs they supply. Anatomy and Physiology 2013-06-19T00:00:00Z During exercise, blood is diverted to the skeletal muscles through vasodilation while blood to the digestive system would be lessened through vasoconstriction. Biology for AP Courses 2022-06-09T00:00:00Z When blood pressure increases, baroreceptors send more frequent action potentials to the central nervous system, leading to widespread vasodilation.
