External pressure significantly affects lung size because the lungs operate based on the principles of pressure and volume, as described by Boyle's Law. When external pressure increases, such as during deep-sea diving or high-altitude environments, it compresses the air within the lungs, reducing their volume and making it harder to expand. Conversely, lower external pressure allows the lungs to expand more easily, increasing their volume. This dynamic is crucial for efficient gas exchange and overall respiratory function.
What else can I help you with?
How does the action of the external intercostal and diaphragm muscles draw air up your nose?
External intercostal and diaphragm increase the volume of the lungs, this action dicreases the pressure of the lungs. (we know pressure moves from the region of higher region to lower, in this case pressure is high in atmosphere and low in lungs). So air gets drew up in our nose.
How Cholesterol affects the respiratory system?
It indirectly affects the respiratory system. Cholesterol affects the circulatory system and there is high blood pressure. Due to high blood pressure, the heart cannot pump a lot of blood to the body which indirectly affects the lungs!
What determine the direction of respiratory gas movement?
partial pressure gradient
What is the pressure difference between the external air and the pleural cavity when inhalation just begins?
The pressure in the pleural cavity becomes more negative compared to the external air during inhalation, which creates a pressure difference. This pressure gradient allows air to flow into the lungs, expanding them for inhalation.
To control my buoyancy as I ascend after a dive I should?
Gradually but continuously exhale. This is not only to control buoyancy, but to prevent damaging your lungs as the air in your lungs expands (due to external pressure decreasing, internal pressure increases)
What is Normal expiration is brought on by?
Normal expiration is brought on by the relaxation of the diaphragm and external intercostal muscles, causing the thoracic cavity to decrease in volume, which increases the pressure in the lungs. This increased pressure pushes air out of the lungs.
How does the atomic bomb affect humans?
first of all, there are many chemicals in the bomb, which affects the lungs greatly. people now that dealed with them, are developing problems.
How does a breath?
Turtles have lungs, but they have different musculature for using the lungs because they cannot expand the chest cavity. Many aquatic turtles additionally take advantage of strategies using external water pressure and downward atmospheric pressure to help force air in or out of their lungs.
Which part of the body is most affected by asthma?
Asthma affects the lungs.
What is the pressure difference between the external air and pleural cavity when inhalation just begins?
At the start of inhalation, the pressure in the pleural cavity is normally about 756 mmHg, while the external air pressure is about 760 mmHg. This creates a pressure difference of 4 mmHg, causing air to flow into the lungs.
When air is no longer moving through the respiratory tract and the airway is open to the environment the pressure within the lungs is equal to .?
When air is no longer moving through the respiratory tract and the airway is open to the environment, the pressure within the lungs is equal to atmospheric pressure. This equilibrium occurs because the open airway allows air to flow freely in and out, balancing the pressure inside the lungs with the external atmospheric pressure.
What effect does choking have on your lungs?
Choking affects the lungs by choking
