The human body is a complex and intricate system made up of various organs and tissues that work together to maintain life. The heart pumps blood throughout the body, supplying oxygen and nutrients to cells while removing waste products. The brain processes information from the senses, controlling movement, emotion, and thought. The skin protects the internal organs from damage and infection, regulating body temperature and aiding in the production of vitamin D. The liver filters toxins from the bloodstream, producing bile that aids in digestion. The lungs breathe in oxygen, expelling carbon dioxide through exhalation.
