The organs of the respiratory system function as
air distributers and gas exchangers
The respiratory system also..
filters warms and humidifies the air that we breathe
Respiratory organs include
nose lungs pharynx larynx trachea etc.
the respiratory system ends in millions of tiny thin walled sacks called
alveoli
Boyle's law states that
the volume of a gas is inversely proportional to its pressure
When the diaphragm contracts, the volume of the thorax increases, thoracic pressure
decreases and air rushes into the lungs
quiet inspiration is the function of
the diaphragm and external intercostal
during normal quiet respiration, the amount of air exchanged between the lungs and atmosphere is called _____ and has a volume of ___ ml
residual volume, 1200 ml
functional residual capacity equals
TV+IRV+ERV
Eupnea is a term used to describe
normal breathing
under normal conditions, air in the atmosphere exerts a pressure of
760 mmHg
Areas where gas exchange cannot take pace are
anatomical dead spaces
all of the following are regulated processes associated with the functioning respiratory system except
control of cell metabolism rate
daltons law is also known as
the law of partial pressure
Temperature
The measurement of the motion of molecules
Residual Volume
The volume remaining in the respiratory system after maximum expiration
Apnea
The temporary cessation of breathing
if oxygen is 21 % of the atmosphere, it will contribute ___ of the total atmospheric pressure
21 %
If alveolar PO equals 100 mm Hg and pulmonary capillary PO equals 40 mm Hg which of the following will occur
O2 will exit the alveoli and enter into capillary blood
Capillary O2 will exit the alveoli at 100 mm Hg
Po Will equalize between the pulmonary capillary and alveoli
PO at standard atmospheric pressure is approximately
160 mmHg
PCO of systemic arterial blood is approximately
40 mmHG
Pneumothorax
Air in the pleural space of the thoracic cavity
Partial pressure
Can be used interchangeably with tension
Nitrogen
The gas of greatest concentration in atmospheric air
Oxygen is carried in blood
As oxyhemoglobin
dissolved in plasma
molecularly as HbO
increasing the carbon dioxide content of blood results in
increased blood Ph
Approximately 97% of oxygen transported as _______, whereas the remaining 3% is transported dissolved in _____
Plasma; hemoglobin
The exact amount of oxygen in blood depends mainly upon...
the amount of hemoglobin present
Bohr Effect
A right shift of the oxygen hemoglobin dissociation curve due to increased PCO
The basic rhythm of the respiratory cycle seems to be generated by
the medullary rhythmicity area
The diving reflex
Is responsible for the astonishing recovery of near drowning victims in cold water
Irritation of the phrenic nerve can cause
Extended periods of hiccups
A broad term used to describe conditions of progressive, irreversible obstruction of expiratory air flow
Chronic Obtrusive Pulmonary Disease
COPD results from
Excessive tracheobronchial sections that obstruct air flow
May results from the progression of chronic bronchitis or other conditions as air becomes entrapped within alveoli causing them to enlarge and eventually rupture
Emphysema
An obstructive disorder characterized by recurring spasms of the smooth muscle in the walls of the bronchial air passages
Asthma
Labored breathing
Dyspnea
Inhaling
