What is the brain?</h3>
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body.
From the diagram, we can conclude that the brain is the input in the system because it is the brain which gives the signals to the glands in the skin in order to perform any activity.
The brain is known to have three main parts:
- the cerebrum,
- cerebellum and
- brainstem
The Cerebrum is the largest part of the brain and is composed of right and left hemispheres.
The brain serves many functions to the human body as it controls our ability to balance, walk, talk, and eat. It coordinates and regulates our breathing, blood circulation, and heart rate.
