Which of the Following Statements Are True of the Maintenance

Which of the following statements are true of the maintenance of blood pressure (BP) (Select all that apply) ?

A) If more blood returns to the heart,the ventricles contract more forcefully to pump it out,and this raises BP.
B) The hormone ADH helps the kidneys conserve water,and helps prevent a decrease in BP.
C) The elasticity of the large arteries helps decrease diastolic BP.
D) If BP decreases,filtration in the kidneys decreases.
E) Aldosterone stimulates the reabsorption of Na+ ions by the kidneys,which lowers BP.
F) If BP decreases,the kidneys secrete the enzyme renin,which stimulates the secretion of epinephrine to prevent a further decrease.
G) Norepinephrine stimulates vasoconstriction in skin,viscera,and skeletal muscles,all of which lower BP.
H) The hormone ANP increases the excretion of K+ ions by the kidneys,which helps conserve water and raise BP.
