A rattlesnake, for instance, has one small pit on each side of its head, filled with thousands of receptor cells, which are actually microscopic-sized infrared sensors. 例如响尾蛇在头部两侧小凹坑里的器官充满数千个受体细胞，这实际上就是显微的红外线感受器。
The heart rate and venous tone were controlled by high-pressure receptor baroreflex, while the peripheral resistance was controlled by high- and low-pressure receptor baroreflexes. 其中，心率和静脉紧张度受动脉压力感受器反射控制，而外周阻力则同时受动脉压力感受器和心肺压力感受器的反射控制。
