    Respiration:
    1. NOSE:
    Before air enters the body, the nose filters it to remove dirt and warms up so that it's at an appropriate temperature.
    2. PHARYNX:
    The pharynx is a muscular tube that carries the air down into the trachea and also carries food to the gullet.
    3. EPIGLOTTIS:
    The epiglottis is a leaf-shaped piece of cartilage that covers the top of the larynx during swallowing. It keeps food out of the lungs and larynx.
    4. LARYNX:
    Larynx sits on the top of the trachea and has a backbone of cartilage that you can feel at the front of your throat.
    5. VOCAL CORDS:
    The vocal cords are at the centre of the voice box and make the sounds when you talk, sing, cough or hum. They are folds of membrane lining
    that vibrate when air flows through them to the lungs.
    6. TRACHEA:
    The trachea which is also known as the windpipe, takes air from the vocal cords to the lungs. It has ribs of cartilage to keep it open.
    7. BRONCHIAL TREE:
    The bronchial tree take the air to the bottom of the lungs.
    8. LUNGS:
    In the lungs, thousands of tiny air sacs called alveoli extend from the end of the smallest bronchioles. They look a bit like bunches of grapes
    hanging off a stem. The left and right lungs are about the same size, except that the left lung has an indentation at the bottom to allow room for
    the heart.
    9. ALVEOLI:
    Oxygen enters your bloodstream through a process called 'respiration'. The walls of the alveoli are thin, allowing oxygen from the inhaled air to
    pass through where it's picked up by passing red blood cells. This 'oxygenated' blood will travel throughout the body, providing vital fuel living
    cells need. After delivering its oxygen, the 'deoxygenates' blood returns to the lungs. Back at the lungs, Co2 passes through the thin walls of the
    alveoli and leaves the lungs when you exhale.

    < Equation of the Respiration >
    Carbohydrates(Glucose) + Oxygen --> Carbon dioxide released into the air + Water + Energy.

    Difference between Breathing and Respiration:
    Breathing is a constant process where you breathe in and out constantly through out the day. Respiration is a process where the body breaks down the oxygen, so that the cells in the body can use it.

    Preparing notes this way can help you as you will retain a lot of info and you can read what you have written down any time even on the phone while you are travelling in the bus or taking a break........You can also post your questions and one of the students may respond to your queries... isn't that GREAT?
