Biological Systems and Processes

Biological systems are complex networks within living organisms that work together to sustain life. These include the circulatory system, which transports nutrients and oxygen; the respiratory system, which enables breathing; the digestive system, which processes food; and the nervous system, which controls activities and responses. These systems rely on processes such as cell functions, energy production, and chemical reactions to maintain health and adaptation. Together, they coordinate to support growth, repair, reproduction, and overall functioning essential for life.
