Physiology
The movement of gases in and out of the lungs
What is ventilation (breathing)?
Chronic inflammatory disease of the airways with reversible airflow obstruction and bronchospasm
What is asthma?
What is the Epiglottis ?
Heard when air is forced through narrow airways
What is wheezing?
During this the intercostal muscles and diaphragm contract expanding the chest wall and lungs
What is inhalation (inspiration)?
An inflammatory condition of the lungs usually caused by viral or bacterial infection
What is Pneumonia?
Cartilaginous tube that serves as the main trunk transporting air from the larynx down towards the lungs
What is the Trachea ?
Harsh, noisy, squeaky sound heard with every breath
What is Stridor?
A passive process where the diaphragm relaxes and the chest wall and lungs recoil
What is exhalation (expiration)?
An inflammatory disease involving narrow airways and poor airflow that can result in alveolar member damage
What is COPD?
Two main branches of these split off from the trachea, leading air directly into each lung
Clicking, bubbling or popping sounds (often likened to Velcro or crinkling paper) typically heard when inhaling
What are Crackles(Rales) ?
This controls the rate, rhythm and depth of breathing
What is the brain stem?
A serous inflammatory lung condition that typically presents 6-72 hours following a major illness or injury
What is ARDS (Acute Respiratory Distress Syndrome)?
Small branching networks of tubes that distribute air deeper into the lungs
What are Bronchioles?
Low pitched, snoring or rumblings sounds occurring when air pathways partially blocked by secretions or inflammation
What is Rhonchi?
Medical term for deficiency of oxygen in body tissues
What is Hypoxia?
Gas in the pleural space
What is a pneumothorax?
What are Alveoli
Harsh, high-pitched vibrating sound heard mostly when inhaling that indicates an obstruction in upper airway
What is Stridor?
