pharynx | Pharynx: Commonly known as the throat; it receives air from the nose/mouth and food. It has three divisions: nasopharynx, oropharynx, and laryngopharynx. |
or/o | mouth |
soft palate | The muscular back part of the roof of the mouth; it moves up during swallowing to block the nasopharynx, preventing food or liquid from entering the nose. |
epiglottis | A lid-like structure at the base of the tongue that closes off the laryngopharynx during swallowing to prevent food from entering the trachea and lungs. |
bronchi | Two large tubes (primary bronchi) that branch from the trachea into each lung, forming the bronchial tree. They further divide into smaller bronchioles within the lungs. |
alveoli | Tiny air sacs at the ends of bronchioles where oxygen and carbon dioxide are exchanged. Surrounded by pulmonary capillaries, they number in the millions in each lung. |
surfactant | A substance that reduces surface tension in the lungs, helping keep alveoli stable and preventing collapse during exhalation. |
right lung | is larger and has three lobes: the upper, middle, and lower (or superior, middle, and inferior). |
left lung | has only two lobes, the upper and lower, due to space restrictions because the heart is located on that side of the body. |
mediastinum | The central area of the chest cavity between the lungs, containing the heart, major blood vessels, esophagus, trachea, bronchi, thymus gland, and lymph nodes. |
pleura | is a thin, moist, and slippery membrane that covers the outer surface of the lungs and lines the inner surface of the thoracic cavity |
phrenic nerves | stimulate the diaphragm | and cause it to contract |
spasm | involuntary contraction |
rhin/o | nose |
diphtheria | Diphtheria: An acute bacterial infection of the throat and upper respiratory tract; its toxins can damage the heart and peripheral nerves. |
pertussis | whooping cough |
croup | An acute respiratory infection in children and infants causing laryngeal obstruction, hoarseness, swelling around the vocal cords, a barking cough, and stridor. |
stridor | is a harsh, high-pitched sound caused by a blockage present when breathing in |
aphonia | is the loss of the ability | of the larynx to produce normal speech sounds |
dysphonia | Dysphonia: Difficulty speaking, including issues like hoarseness, weakness, or voice cracking during puberty. |
