Physiology

QuestionAnswer
The mechanism that produces pulmonary ventilation is one that establishes a gas pressure gradient between the atmosphere and the alveolar air.
The volume of air exhaled normally after a typical inspiration is called _____ volume. tidal
Hyperpnea means a(n) increase in breathing.
The apparatus used to measure the volume of air exchanged in breathing is called a(n) spirometer.
What variations exist in the body to temporarily store or carry oxygen? neuroglobin myoglobin fetal hemoglobin all of the above all of the above
An obstructive lung disorder that is characterized by recurring spasms of the smooth muscles in the wall of the bronchial air passages is asthma.
The sensors that provide feedback information to the medullary rhythmicity area are the central chemoreceptors and peripheral chemoreceptors.
More than two-thirds of the carbon dioxide carried by blood is carried in the form of bicarbonate ions.
An increase in carbon dioxide in the blood causes a drop in pH in the blood.
Pressure gradients are established by changes in the thoracic cavity.
The compound formed when carbon dioxide combines with hemoglobin is carbaminohemoglobin.
During inspiration, as the size of the thorax increases, the intrapleural and alveolar pressures decrease
The forced expiratory volume test can determine the presence of respiratory obstruction by measuring the volume of air expired per second during forced expiration.
The _____ represents the largest volume of air an individual can move in and out of the lungs. vital capacity
According to the law of partial pressures, the partial pressure of gas in a mixture of gases is directly related to the concentration of that gas in the mixture and to the total pressure of the mixture.
When carbon dioxide dissolves in water, some of the carbon dioxide molecules associate with water to form carbonic acid.
Oxygen enters blood from alveolar air because the partial pressure of alveolar air is greater than the partial pressure of incoming blood.
