Answer:
The correct answer to fill in the blank is: sensory reception.
Explanation:
Sensory receptors are used to receive stimuli that help us react to changes in the environment, both internal and external.
There are five types of sensory receptors: thermoreceptors (react to changes in temperature), mechanoreceptors (detect physical deformation), chemoreceptors (detect changes in metabolic concentrations, pH, smell and taste), nociceptors (respond to pain), and photoreceptors (respond to visual stimulus and are located in the retina).
