And releases epinephrine and norepinephrine into the blood making your heart pump faster.

并会向血液中释放肾上腺素和降肾上腺素使你的心跳加速。

This is because the nicotine in cigarettes released epinephrine and norepinephrine, which increase your heart rate and narrowed blood vessels.

这是因为烟草中的尼古丁会释放肾上腺素和去甲肾上腺素。

Cortisol also helps to maintain the blood pressure by increasing the sensitivity of peripheral blood vessels to catecholamines- like epinephrine and norepinephrine, and this narrows the blood vessel lumen.

皮质醇也帮助维持血压，增加周围血管对如肾上腺素和去甲肾上腺素等儿茶酚胺的敏感性，这会缩小血管腔。

After the game is over, and the hormones are no longer needed, epinephrine and norepinephrine break down into metabolites like homovanillic acid or HMA, and vanillylmandelic acid, or VMA.

在比赛结束而不再需要这些激素时，肾上腺素和去甲肾上腺素分解成代谢产物，例如高香草酸（HMA）和香草扁桃酸（VMA）。

Diagnosis of neuroblastoma usually starts with testing for HMA and VMA in the blood or urine, since high levels those metabolites may indicate tumors that secrete epinephrine and norepinephrine.

对于神经母细胞瘤的诊断，通常先检测血或尿中的HMA和VMA，这是因为代谢产物含量高可提示肿瘤在释放肾上腺素和去甲肾上腺素。

But on smooth muscle cells that control other blood vessels, there are lots of beta receptors for epinephrine and norepinephrine, and when they are activated, they make the muscles relax, letting more blood flow through.

但是在控制其他血管的平滑肌细胞上，有许多肾上腺素和去甲肾上腺素的β受体，当它们被激活时，它们使肌肉放松，让更多的血液流过。
