    Study Notes

    Immune System Study Notes

    • Lymphocytes are a type of white blood cell
    • Bacteria, viruses, and cellular debris are also part of the immune system
    • Signs and symptoms of inflammation include swelling, redness, heat, and pain
    • Inflammatory fluid leaking out the capillaries causes these symptoms.
    • Injuries from pressure or bacterial toxins can also cause inflammation.
    • The right lung is shorter, broader, and larger than the left lung. The right lung has 3 lobes—superior, middle, and inferior. The left lung has 2 lobes—superior and inferior. The left lung has a cardiac notch that accommodates the heart. The left lung handles 45% of gas exchange, and the right lung handles 55%.
    • Common respiratory terms include apnea (temporary cessation of breathing), bradypnea (abnormally slow breathing), Cheyne-Stokes respirations (an abnormal breathing pattern), dyspnea (labored or difficult breathing), hyperventilation (increased rate and depth of respirations resulting in lowered blood levels of carbon dioxide), hypoventilation (reduced rate and depth of respirations resulting in increased blood levels of carbon dioxide ), Kussmaul respirations (deep gasping respirations associated with diabetic ketoacidosis), orthopnea (labored breathing that occurs when a person is lying flat but improves when standing or sitting up), and tachypnea (rapid breathing)
