HICCUPS • Diaphragm, the muscle below your chest cavity, sudden jerks and you find yourself sucking in air quickly. • The air flow causes the epiglottis to snap shut, which makes the “hiccup” sound.
SNOT AND BOOGERS • Snot Mucus! • Mucus is a thick, slimy substance made of water, salt, and chemicals. It lines your nasal cavity, trachea, and bronchial tubes. • Boogers Dried up snot (mucus) combined with the dust, pollen, dirt, and bacteria the mucus collected when cleaning the air. • The average person swallows about a quart of snot a day.
SNEEZE • Air and mucus from the nasal cavity blast out of your nose at a high speed. • Body uses this mechanism to clear the airways out to prevent infection and keep air clean. • A sneeze triggered by something irritating the nasal cavity. • Air from a sneeze can travel up to 100 mph!
COUGH • A cough is a natural reflex that protects your lungs. • Coughing helps clear your airways of mucus full of dirt, dust, and bacteria. • Helps prevent infection of lung.
ASTHMA • Asthma is caused by inflammation (swelling) in the airways (bronchiole). • When an asthma attack occurs, the muscles surrounding the airways become irritated and tightened. The lining of the air passages swell. • This reduces the amount of air that can pass by, and can lead to wheezing sounds.
BRONCHITIS • Swelled, infected bronchi tubes. • Infection causes a build-up of thick mucus.
EMPHYSEMA-smoking destroys lung tissue as well as breathing passages causing difficulty in breathing.-Not able to get enough oxygen or eliminate carbon dioxide, causing shortness of breath
LUNG CANCER • 140,000 Americans die each year from lung cancer. • 40 chemicals in cigarettes cause cancerous growths and tumors to take over the lungs, taking up space where gas exchange should be occurring.
HYPERVENTILATE • Rapid or deep breathing that can occur with anxiety or panic. • Excessive breathing leads to low levels of carbon dioxide in your blood.
PNEUMONIA • infection of one or both lungs which is usually caused by bacteria, viruses, or fungi. • Pneumonia is the sixth leading cause of death in the United States.
COLLAPSED LUNG • Collection of air in the space around the lungs that has leaked out from a lung. • This buildup of air puts pressure on the lung, so it cannot expand as much as it normally does when you take a breath. • The escaped air needs to be drained surgically to let the lung expand and fill with oxygen normally.
PULMONARY EMBOLISM • An artery to your lung becomes blocked. • Gas exchange to the blocked part of the lungs is impossible.
