    Study Notes

    Respiratory System

    • The primary function of the respiratory system is gas exchange, allowing the body to take in oxygen and release carbon dioxide.

    Circulatory System

    • A common misconception is that the circulatory system only transports blood. It also plays a crucial role in regulating body temperature and transporting nutrients and waste products.

    Endocrine System

    • The endocrine system is primarily responsible for hormone regulation in the body.

    Digestive System

    • Absorption of nutrients is a key function of the digestive system. Production of hormones is NOT a function of the digestive system, although some hormones are produced in the digestive tract.
