WebbTake temperature as an example (see diagram opposite). The thermoreceptor responds to small increases in temperature BUT the nociceptor only responds to temperatures above 44-46 degrees C – the … Webb28 feb. 2024 · This ensures that the tissue will have enough oxygen to support its higher level of metabolism. Maintaining internal conditions in the body is called homeostasis (from homeo-, meaning similar, and stasis, meaning standing still). The root “stasis” of the term “homeostasis” may seem to imply that nothing is happening.
