The human interaction function By David Llorente Lagares 4ºC
HUMAN INTERACTION FUNCTION It is obtaining information from the world around us and from our body, reacting to that information. To perform this function we use: Sense Organs Nervous System Effectors
Sense organs Our sense organs receive information from the world around us and from our own body. There are five senses: Hearing Sight Touch Taste Smell
HEARING The ears: They capture sound vibrations that travel through the air. They are connected to our sense of hearing and our balance.
SIGHT Our eyes: They capture light and images of our environment. They are connected to our sense of sight.
touch The skin receptors: Detect contact and changes of temperatura that we perceive as touch.
Taste The taste buds: Capture substances that enter our mouths and we perceive them as taste.
smell The olfactory bulb in the nose: Capture substances in the air that we inhale and we percieve as smell.
Nervous system It is the system that: Receives signals from the sense organs. Interprets the information and reacts to it. Consists of: The encephalon The spinal cord The nerves
effectors The parts of our body that respond to nerve signals. They are: The muscles The glands
