A body system is a collection of parts able to work together to serve a common purpose – growth, reproduction and survival. Each part of a system depends on the other parts to perform tasks that can’t be achieved by single parts acting alone. Each individual system works in conjunction with other systems to improve our chances of survival by maintaining a stable internal body environment. This stable environment is known as homeostasis. An example of the way these systems are inter-related is the blood. It is part of the cardiovascular system and it carries products of digestion (digestive system) to body cells, excretory wastes (excretory system) to the kidneys and hormones (endocrine system) to target organs such as those forming part of the reproductive system.
