• 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.
