The human body is made up of several organ systems that work together as one unit. In the pyramid of life that organizes all of the elements of life into categories, organ systems are nested between an organism and its organs. Organ systems are the groups of organs that are within an organism.
The human body is a biological machine made of body systems; groups of organs that work together to produce and sustain life. Sometimes we get lost while studying about cells and molecules and can’t see the forest for the trees. It can be helpful to step back and look at the bigger anatomical picture.
The main purpose of their joint working system is to facilitate life, movement, cognitive functions, growth, repair, reproduction, etc. Some of the vital human body systems include the central nervous system, respiratory system, circulatory system, digestive system, immune system, reproductive system, skeletal structure and muscular system.
