Ventilation
What is Atelectasis in the context of the respiratory system?
A condition characterized by the collapse of lung tissue
What is the role of surfactant in the respiratory system?
Reducing the surface tension of alveolar fluids
What factors can affect the binding and release of oxygen with hemoglobin?
Decreasing partial pressure and increasing blood pH
Which factors can increase the rate of oxygen transport from the lungs to the tissues?
Cardiac output, increased number of RBC, and exercise
What happens to the partial pressure of oxygen in the tissue as oxygen diffuses into the cells?
It decreases
The upper respiratory system consists of the trachea and lungs.
False
The alveoli are responsible for the exchange of oxygen and carbon dioxide between the atmosphere and the blood.
True
The visceral pleura is a layer of tissue that lines the inside of the chest wall.
False
The larynx is a pathway shared by both air and food.
False
The serous lubricating fluid between the pleural layers prevents friction between the lungs and chest wall.
True
Increased lung compliance is associated with a higher risk of Atelectasis.
False
Recoil is a process that occurs during the inspiration phase of breathing.
False
Surfactant is a lipoprotein that assists in reducing the surface tension of alveolar fluids.
True
Partial pressure is the pressure of all gases in a mixture that contributes to the overall pressure of the gas.
False
Exercise decreases the rate of O2 transport from the lungs to the tissues.
False
The medulla and pons are responsible for maintaining a clear airway.
False
COPD stands for Chronic Obstructive Pulmonary Disorder.
False
Anterior neck muscles are one of the accessory muscles of respiration.
True
Intrapleural pressure is the pressure within the lung.
False
The normal range of Tidal Volume is 500ml.
True
Test your knowledge on the integration of hematologic, cardiovascular, and respiratory systems in the delivery of oxygen and removal of carbon dioxide. Learn about the structural divisions of the respiratory system and its functions in gas exchange.
