Energy Systems
The human body relies on various systems to provide energy and nutrients essential for survival. explains that the digestive system breaks down food to extract necessary materials, while the circulatory system transports these nutrients to cells throughout the body 1. The respiratory system plays a crucial role by bringing in oxygen and expelling carbon dioxide, which is vital for the metabolic processes that generate energy 2.
The circulatory system carries nutrients, gases, hormones, and other things, including white blood cells throughout the body.

Together, these systems ensure that the body has a constant supply of energy and maintains homeostasis 2.

Metabolism
Metabolism involves a series of chemical reactions that convert nutrients into energy, essential for the body's functions. highlights the importance of the respiratory system in providing oxygen, which is necessary for these metabolic reactions 3. The nervous and endocrine systems also play significant roles in regulating these processes and responding to environmental stimuli.
The nervous system specializes in fast, specific control of particular things, like moving the legs here, running over here, getting frightened and running off or hiding.
