Sensory systems (visual, auditory, gustatory, olfactory, etc.) are represented by highly specialized receptors capable of perceiving the action of stimuli and converting their energy into electrical impulses. Impulses are delivered to the cerebral cortex, where they are processed and sensations are formed. Thus, the function of connecting the body with the external environment is realized.
The following organ systems communicate with the external environment: the respiratory system (expressed in the exchange of gases between the body and the external environment), the muscular system (the movement of the body or its individual parts in space), the nervous system (ensures its adaptation to environmental influences), and the sensory system (perception of signals from the outside world).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
