19. Cardiovascular System: Blood Vessels

Blood pressure in arteries, capillaries, and veins

Blood Pressure

Blood Pressure in Arteries, Veins and Capillaries

Regulation of blood pressure with baroreceptors

 Antidiuretic hormone acts on arterioles and kidney tubule cells to increase blood pressure. Angiotensin II acts on arterioles to increase blood pressure. Epinephrine acts on arterioles and the heart to increase blood pressure. Atrial natriuretic peptide acts on arterioles to lower blood pressure. 

 Which of the following acts on the kidneys and blood vessels to raise blood pressure? 

Anatomy and Physiology: Blood Flow and Pressure

Regulation of Blood Pressure (Hormones)

Blood Pressure in Arteries is Higher than in Veins

 The kidneys act both directly and indirectly to regulate arterial pressure and provide the major long-term mechanism of blood pressure control by altering blood volume. 

 The major long-term mechanism of blood pressure control is provided by the __________. 

Baroreflex Regulation of Blood Pressure, Animation

Arterial Baroreceptor Reflex

 Short-term blood pressure regulation involves both neural and hormonal controls. Neural control is regulated by higher order brain centers, chemoreceptors, and baroreceptors. Long-term control of blood pressure is achieved through direct and indirect renal (kidney) control mechanisms.  

 Baroreceptors are effective in long-term regulation of blood pressure. 

Renin angiotensin system regulates blood pressure

 the level of carbon dioxide in the blood 

 Baroreceptors are sensitive to changes in blood pressure. 

 Most neural controls of blood pressure involve input from baroreceptors, which are sensitive to __________.
