    Study Notes

    Breathing Process

    • When taking a deep breath, air enters through the mouth or nose and follows an identical path, meeting in the back of the throat.
    • The air then travels down towards the Adam's apple (voice box), which helps control the voice and allows for changes in pitch.

    Adam's Apple (Voice Box)

    • The Adam's apple is a structure in the middle of the throat that everyone has, not just men.
    • It's located in a notch in the throat and helps control the voice, allowing for changes in pitch.

    Trachea and Lungs

    • Air passes through the trachea and enters the lung area, which is divided into the right and left lungs.
    • The right lung has three lobes (upper, middle, and lower), while the left lung has two lobes.
    • The left lung has a cardiac notch due to the heart's presence during development.

    Heart and Diaphragm

    • The heart is located in the middle, surrounded by the lungs, and takes up space in the left lung.
    • The diaphragm muscle makes up the floor of the thorax (chest cavity), while the ribs make up the walls.

    Bronchial Tree

    • The lungs have a tree-like structure, with air passing through the trachea and branching into smaller tubes.
    • The bronchial tree has a main trunk (trachea) that splits into smaller branches, serving different lobes of the lungs.

    Alveoli and Gas Exchange

    • Air reaches the alveoli, microscopic sacs where gas exchange occurs.
    • Oxygen from the air enters the blood, and carbon dioxide waste is released from the blood into the alveoli.
    • The oxygen-rich blood then transports oxygen to the body's cells, while the carbon dioxide is exhaled out of the body.
