This tissue contains millions of chemoreceptors, nerves that capture odor molecules.

种组织包含了数百万学感受器，也就是能捕获气味分子神经细胞。

Within minutes or even seconds of reaching altitudes of 1,500 meters, carotid chemoreceptors in your neck sense your blood's low oxygen pressure.

如果在几分钟甚至几秒钟内到达 1500 米以上海拔，脖子里颈动脉学感受器就会察觉到血液氧气压力过低。

This mutant, Pectiquad, was missing just the four specific sensors, the chemoreceptors, known to detect amino acids.

种突变体Pectiquad仅缺少四种特定传感器，即已知能检测氨基酸学感受器。

They call on chemoreceptors in our taste buds and nasal passages to detect molecules in our food and the air around us.

它们利用我们味蕾和鼻腔通道学感受器来检测我们食物和周围空气分子。

Thermoreceptors respond to changes in temperature. photoreceptors react to light, chemoreceptors pay attention to chemicals, and mechanoreceptors respond to pressure, touch, and vibration.

热感受器对温度变做出反应。光感受器对光做出反应，学感受器关注学物质，机械感受器对压力、触摸和振动做出反应。

These chemoreceptors are located in our brains and some large arteries that deliver blood to the brain.

些学感受器位于我们大脑和一些向大脑输送血液大动脉。

The central chemoreceptors are located in the medulla oblongata, and they're sensitive to changes in carbon dioxide levels.

枢学感受器位于延髓，对二氧碳含量变敏感。

The peripheral chemoreceptors are located in the aorta and carotid arteries, and they deliver blood to the brain.

外周学感受器位于主动脉和颈动脉，它们向大脑输送血液。

Therefore, we have what we call chemoreceptors, which serve to sense changes in carbon dioxide and oxygen levels in our body.

因此，我们有学感受器，用来感知我们体内二氧碳和氧气水平变。

Just as the ear's mechanoreceptors or the tongue's chemoreceptors convert sounds and chemicals into action potentials, so too do your eyes' photoreceptors convert light energy into nerve impulses that the brain can understand.

就像耳朵机械感受器或舌头学感受器将声音和学物质转为动作电位一样，眼睛光感受器也将光能转为大脑可以理解神经脉冲。

Central chemoreceptors located in the brain sense changes in carbon dioxide, while peripheral chemoreceptors located in the arteries delivering blood to the brain sense changes in both carbon dioxide and oxygen.

位于大脑央学感受器感知二氧碳变，而位于动脉周围学感受器感知二氧碳和氧气变，些动脉将血液输送至大脑。
