Study Guide to the Systems of the Body

Before you begin to study the different structures and functions of the human body, it is helpful to consider its basic architecture; that is, how its smallest parts are assembled into larger structures. It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere Figure 1. To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of which are hydrogen, oxygen, carbon, nitrogen, calcium, and iron. The smallest unit of any of these pure substances elements is an atom. Atoms are made up of subatomic particles such as the proton, electron and neutron.

Our bodies are made up of 11 basic organ systems that work together to manage all the functions that keep us healthy and alive. These systems, while interdependent, can become out of tune and when one is not functioning properly, the others will attempt to correct the problem and all the systems will work together to try to create what is known as homeostasis, a state of balance within the body. While none of the systems can work independently, they all carry out distinctive duties that manage specific areas of our bodily functions. The 11 systems are made up of the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems. The VA defines 14 disability systems which are similar to the body systems but are separated differently for rating purposes. These systems are listed with the medical listing and are identified independently when necessary. For Individual Unemployability ratings; if you are rated with more than one disability within one body system, your rating will increase towards unemployability.

The human body is actually an amazing coalition of many different systems that work together to keep everything functioning correctly. For example, some systems handle food and energy, while others focus on taking in oxygen and moving it around the body.
