Why is it important that the body have two control systems rather than one?
It is important because that way our body can function better than if we only had one control system. Our body has two control systems: the nervous system and our endocrine system. With both of these, it is easier to respond to our surroundings and comprehend things better. The nervous system is important because it transfers messages from the brain to the body. It is the system that allows us to quickly react to what happens. An example would be the widening of your eyes when something frightens you. Our nervous system has two parts: the Parasympathetic System and the Sympathetic Nervous System. The Sympathetic system helps us decide whether one should prepare our body for fight or flight, which is known as the flight-or-flight response. As for the Parasympathetic System, it assists in calming down or body. Some signs of this system at work would be the decrease of heart beat and heart rate.
The Endocrine System is also a very important part of communication because it secretes hormones that helps our body survive the conflicts that we may face. Some hormones would include endorphins, adrenaline, and growth hormone.
In all, it is better to have two control functions such as the Endocrine System and the Nervous System because when there is two and not one control system, the communication we receive is of better quality.
