Definition
Body systems are groups of organs and tissues that work together to perform important jobs for the body. Some organs may be part of more than one body system if they serve more than one function. Other organs and tissues serve a purpose in only one body system. Examples include the respiratory system, nervous system, and digestive system.
All body systems are necessary for a complex organism to be able to survive and reproduce. This article will focus on the systems of the human body; similar systems are required by all animals, but the details of how they accomplish their tasks may vary.
Functions that must be performed by an animal to stay alive include:
Absorbing oxygen for use in cellular respiration
Excreting carbon dioxide produced during cellular respiration
Ingesting and processing food to obtain sugars and other nutrients.
Transporting necessary substances, such as oxygen and nutrients, to all cells in the body
Clearing toxic waste products from the body.
Responding to changes in the environmental conditions
Protecting the organs from the environment.
Fighting pathogens
Additionally, for a species to survive, its individuals must be able to reproduce.
How do our organs and tissues work together as systems to accomplish these tasks?
