    • Lungs: Facilitate gas exchange (oxygen and carbon dioxide).
    • Brain: Controls and coordinates bodily functions.
    • Kidneys: Filter waste products from the blood.
    • Organ Systems: Organs work together in organ systems to perform specific functions:
    • Circulatory System: Transports blood, oxygen, and nutrients.
    • Respiratory System: Facilitates gas exchange.
    • Nervous System: Controls and coordinates bodily functions.
