physiological systems

Physiological systems are groups of organs and tissues that work together to perform essential functions in the body. These include the circulatory system (which pumps blood), the respiratory system (for breathing), the digestive system (for processing food), and the nervous system (which controls body functions and responses). Each system has specific roles but interacts with others to maintain overall health and balance, known as homeostasis. Understanding these systems helps us appreciate how our bodies operate and respond to various challenges, contributing to our well-being.
