Cards (97)
- objectives of the respiratory system
- inflow and outflow of air between lungs and atmosphere
- gaseous exchange
- at what level are the lungs attached
- shape of mammalian lungs
- major organs of respiratory system
- functional unit of lungs
- what kind of structure are lungs made of
- mammalian lungs are more _ than avian lungs
- pleura closes to lung
- pleural located at chest wall
- extent of which the lung expands for each unit increase in transpulmonary pressure
- difference between alveolar pressure and pleural pressure
- pressure of fluid in the thin space between lung pleura and chest wall pleura
- pressure of air inside lung alveoli
- when the glottis is open and no air is flowing in/out lungs, it is equal to
- refers to air pressure in lungs and the passages leading to them
- air pressure in lungs has to be
- refers to pressure in the thorax outside the lungs
- other term for intra pleural pressure
- tendency of lungs to collapse
- reasons for recoil tendency
- allows complete division in the thorax of mammals
- accumulation of fluid in pleural cavity
- ways to counteract recoil tendency
- anything that acts on a surface
- substance that prevents air sacs of lungs from collapsing due to surface tension created by water molecules on the surface of alveoli
- pulmonary surfactant provides _ that makes the alveoli stable when an individual exhale
- lipid component of pulmonary surfactant
- pulmonary surfactant is a mixture of
- secretes the calcium ions of pulmonary surfactant
- when is pulmonary surfactant secreted
- deficiency of pulmonary surfactant
- symptoms of respiratory distress syndrome
- respiratory distress syndrome is common in
- other term for respiratory distress syndrome
- chemical reaction where O2 is used to break down glucose in order to generate energy used for cell function
- 2 types of respiration
- gaseous exchange between alveoli and blood
- gaseous exchange between interstitial fluid and blood
