What happens to the pressure inside the thorax when you exhale?
When you exhale, the pressure inside the thorax increases slightly due to the contraction of the diaphragm causing a decrease in thoracic volume. This increase in pressure helps to push air out of the lungs.
How do pressure changes with the thorax make expiration possible?
During expiration, the diaphragm and intercostal muscles relax, causing the thoracic cavity to decrease in volume. This decrease in volume increases the pressure within the thorax, which pushes air out of the lungs. This process facilitates expiration by creating a pressure gradient that allows air to flow out of the lungs.
What muscle flattens to increase the volume of the thorax?
The diaphragm is the muscle that flattens to increase the volume of the thorax. During inhalation, it contracts and moves downward, creating more space in the thoracic cavity, which allows air to be drawn into the lungs. This action is essential for efficient breathing and gas exchange.
When temperature decreases what does the volume of liquid water do increase or decrease?
The volume of water increase under 3,98 oC.
What would increase or decrease net filtration pressure?
An increase in blood pressure, blood volume, or permeability of the filtration barrier would increase net filtration pressure. On the other hand, a decrease in blood pressure, blood volume, or an increase in plasma protein concentration would decrease net filtration pressure.
What happens to the pressure inside the thorax when you exhale?
When you exhale, the pressure inside the thorax increases slightly due to the contraction of the diaphragm causing a decrease in thoracic volume. This increase in pressure helps to push air out of the lungs.
How does temperature affect the volume of substance?
An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.
What two things affect density?
The two main factors that affect density are the mass of an object and its volume. An increase in mass or a decrease in volume will lead to an increase in density, whereas a decrease in mass or an increase in volume will result in a decrease in density.
How does a change volume affect an objects density when mass stays the same?
With constant mass, a decrease in volume will increase the the density. Conversely, an increase in volume will decrease the density.
Will increase the volume of the gas?
An increase of the temperature or a decrease of the pressure.
How does the thorax enable us to breathe?
the volume of breathing in increases and when breathing out it decreases, the pressure in Inhaling decreases and the Exhaling increases.
How bronchial asthma effect on lung volume and capacity increase or decrease and why?
decrease -
Will the volume of oxygen increase or decrease after burning?
oxygen is used ... volume decreases.

When temperature decreases what does the volume of liquid water do increase or decrease?

When the volume of gas decreases would the pressure increase or decrease?
It would increase.
