Welcome to today's lecture. Last week we looked at the?respiratory system?and how the?lungs?separate oxygen from other gasses which we breathe. Today, we will be looking at co-dependence within three of the body's most important systems: the central nervous system (CNS), the?cardiovascular system?and the?digestive system.
The nervous system can be divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system is comprised of the?brain?and the?spinal cord, and is responsible for processing the information which is sent to or received from the peripheral nervous system which is made up of the body's?nerves. The brain processes information while the spinal cord acts as a delivery system for the information and impulses.
