Valsalva Maneuver
Air is used in the speech process.

Accounts for more deaths than any other cancer. Cigarette smoke, usually follows or accompanies COPD.
Lung Cancer
Muscles operate vocal cords. 2 Pair of mucoso folds & elastic ligaments that stretch across glottis and vibrate when air passes between them.
Produces Sound - Functions of Larynx
From TB virus dispersed in spittle with a sneeze, or via blood or air.
Tuberculosis
Functions as air conditioner to warm, clean, humidify air. Detects ordors & resonates voice.
Nose
Low blood O2 - inadequate pulmonary exchange.
Hypoxemia Hypoxia
Smooth muscle, cilia ends in first part of these, lead to Aveolar ducts.
Respiratory Bronchioles
Distensibility of lungs. Fibrosis, COPD.
Pulmonary Compliance
Protrudes outward, framework of bone (superior) and cartilage (inferior half).
External Nose
Due to irritants, cold air, PSNS, histamine, shock, excess mucous, asthma, etc.
Bronchiole Diameter
Throat - common passage for food and air, connects nasal & oral cavities to larynx 13 cm (5 in) muscular tunnel from nasal cavity to larynx.
Pharynx
Inflammation of the tonsils in the pharynx.
Tonsilitis
"Sense of Smell", sensory cells in roof of nose detect odor of molecules dissolved in mucos.
Olfaction
Loading carbon dioxide and unloading oxygen - Opposite of process in lungs.
Internal Respiration
Semi-Permanent surgical opening (patient breaths through this openeing).
Tracheostomy
Inflammation and hyperpolasia (growth) bronchial mucosa = "pink puffers"
Chronic Bronchitis
In case of blockage, incision of tube into trachea on central surface of neck through which patient can breath or be ventilated.
Tracheotomy
Allergen triggers histamine and inflammatory chemicals that cause internal bronchoconstriction and sometimes suffocation.
Asthma
Microscopic balloon-shaped structures that cluster in grape-like sacs, one cell thick to allow gas exchange with pulmonary capillaries. 150 million.lung=70m * 2 of surface area if stretch out flat.
Aveoli
Exchange of O2 and Co2 at the body cell capillaries.
Internal Respirations
First branch from 1% bronchi inside of lungs, 2 in left, 3 in right.
Two 2% (lobar) bronchi
Amount of air above TV that can be forcibly exhaled. 1400ml.
Expiratory Reserve Volume
Tongue and lips form words, loudness due to force of air through passages change tensions (open & close glottis) to change pitch of sound - Cords are longer and thicker in men due to testosterone.
Sound
Complete process of supplying O2 to body cells and removing waste Co2 from body.
Respiration
Tears and paranasal sinuses lined with mucous drain into nasal cavity - why nose runs with crying.
Tears
Passive process, like elastic recoil, diaphragm relaxes and returns them to original dimensions.
Expiration
Spongy parenchyma containing air sacs. Conical structures, appear solid with base resting on diaphragm, apex is blunt peak, either side of heart, protected by rib cage.
Lungs
Maximum air lungs can contain RV + VC.
Total Lung Capacity
Between soft palate & hyoid, contains palatine & lingual tonsils, stratified squamous. Oral cavities opens here, passageway for food & air that meets nasopharynx.
Oropharynx
Collapsed lung, lose pressure, can't inhale. Also caused by airway blockage.
Atelectasis
Voice box - 4cm cartilagenous chamber with muscular walls. Triangular, with apex crating "Adam's apple" on front of neck (prominent in men).
Larynx
Volumes & capacities ae dependent on body size. Some values change with age, sex, disease.
