Unit 5/21 P4 & M3
P4+M1 TASK 2
Functioning Of Body Systems
Each system in the body plays an important role in energy production, which supports the body in many ways: giving off a variety of movements and interacts systems which supply energy for the activity.

What is energy?
Energy can make changes possible. We use it for our every day lives, it helps to move cars over road and boats over water. Energy is also used to allow our bodies to grow, keep warm and help our minds think.
Scientific define energy as the capacity to do work. Energy cannot be destroyed or created, only transported from one source to another.
Forms of energy • Potential Energy:
Potential is the stored energy of position and the energy of position- gravitational energy. When an object is displaced from its original position and there is energy pulling it back to that position, this works with potential energy. This is when a moving object no longer has kinetic energy; it has potential energy instead. • Chemical energy:
Is energy stored which are in the bonds of the atoms and molecules. Batteries biomass, natural gas and coal are examples of stored chemical energy. When chemical energy is burnt it is converted to thermal energy such as burning wood in a fire place. In the human body the glucose is said to have ‘chemical energy’ this is because when chemicals react with oxygen, it releases energy. • Kinetic Energy:
Kinetic energy is the energy of motion, its all about where movement happens; even it’s just a simple movement, it still has kinetic energy, like just clapping, dancing, singing, writing, talking, etc. also it’s the energy of motion.

Role of the energy in the human body
The Cardiovascular system
The human body is made up of the heart and blood vessels; it helps cooling and transportation system for the human body. The main role is to circulate blood through a network of vessel throughout the body to provide individual cells
