Sound intensity decreases when what decreases?
Sound intensity decreases when amplification (volume) decreases.
What decreases when the intensity of sound decreases?
The amplitude of the sound waves decreases as the intensity decreases.
When the distance between the objects decreases the electrical force increase or decreases?
decreases
What happens to density during thermal contraction?
It increases. The volume of a material decreases in contraction, while the mass remains the same.
What happens to the thermal energy of an object as temperature decreases as it increases?
it decreases because when an object is moving as the temperature decreases the object decreases
What is the effect of respiration on the heart sounds?
during inspiration, intrathoracic pressure is decreased.
Does negative intrathoracic increases with inspiration?
Yes.
The diaphragm contracts and the pressure in the chest cavity decreases during?
Inspiration
What happens to lung volume during inspiration?
Chest cavity volume increases during inahalation, and decreases during exhalation.
What is the changes in size of thoracic cavity during the contraction and relaxation of diaphragm?
When the Diaphragm contracts, it is pulled down, and is pulled back up when it relaxes.Also, when you inhale, it contracts. When you exhale, it relaxes.
How does positive-pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
How does positive pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
Why pause between inspiration and expiration in bronchial breathing?
inspiration is an active process that takes place by creation of negative intrathoracic pressure, in normal states where breathing is vesicular, even at a low negative pressure air keep on flowing into alveoli but in bronchial breathing as alveoli are either filled with secretions as in consolidation or a cavity is already filled with air and other contents, no movement of air takes place at the end inspiration despite of negative intrathoracic pressure thereby causing a pause between inspiration and expiration- now pay me thousand dollar!
What is an intrathoracic node?
An intrathoracic node is a node within the chest cavity.
What is the intrathoracic pressure?
Negative intrathoracic pressure is the normal pressure in the area between the pleura of the lungs and the chest wall. The pressure is considered negative because it is less than the atmospheric pressure.
Intrathoracic pressure definition?
the amount of pressure built up in the lungs during inhalation which causes a vaccum affect.
What is the medical terminology for inside the chest?
Intrathoracic is the medical term meaning inside the chest. The heart and lungs are intrathoracic.
