when you breathe the diaphragm makes your lungs expand. the expansion causes the pressure inside your lungs to be lower than outside your body. since fluid (air) goes from high to low to air flows into your lungs.

Blood pressure by itself won't affect breathing. Breathing is regulated by the level of carbon dioxide in your blood (more specifically, carbon dioxide creates carboxylic acid in your blood and this pH decrease causes you to breath) unless you've suffered trauma to the brain. Blood pressure may indirectly cause carbon dioxide levels to raise due to increased metabolic demands of the body to maintain the higher blood pressure

When air pressure is Low it becomes very difficult to breath simply because air moves from high partial pressure to low partial pressure.

Does the attitude of an area affects the breathing rate?

Yes the altitude of the area does affect the breathing rate becaue the higher you go the lower the air pressure and the the lower you go the lower the air pressure.


As you rise further in the atmosphere air pressure does what?

As you rise higher in the atmosphere, air pressure decreases. This is because the higher you go, there is less air above pushing down on you, resulting in lower air pressure. This decrease in pressure can affect breathing and gas exchange in the body at high altitudes.


How does Evolutionary Trends affect Irreversibility?

Air-breathing animals do not return to breathing water.


How does pressure affect the air?

Atmospheric pressure systems are made of air.


How does altitude affect density and air pressure?

Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.


How does the air affect pressure systems?

Atmospheric pressure systems are made of air.


How do clouds affect air pressure?

Clouds can affect air pressure by blocking or reflecting sunlight, which can affect the temperature of the air below the cloud. As air temperature changes, the pressure exerted by the air also changes. Additionally, clouds can contribute to the formation of weather systems such as low or high pressure areas, which can further impact air pressure.


How does air pressure affect the environment please answer?

Air pressure affect the environment as by creating a type of force and just like liquid creates a pressure .


Does air pressure affect gravity?

Air pressure does not directly affect gravity. Gravity is a fundamental force that acts uniformly on all objects regardless of air pressure. However, changes in air pressure can influence the density of the air, which may indirectly affect the behavior of objects falling through the atmosphere due to air resistance.


How does air pressure affect air movement?

Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.


Does air pressure increase in a mine?

Yes, air pressure can increase in a mine, especially in deeper parts of the mine where the weight of the overlying rock puts pressure on the air. This increased air pressure can affect ventilation and breathing for miners, so ventilation systems are used to regulate the pressure and ensure safe working conditions.


Does having a common cold affect blood pressure?

The common cold can affect breathing and breathing does affect blood pressure! If you aren't breathing properly blood pressure can read high especially if you are almost stifling and nervous; very low if no air is reaching your lungs, etc adequately.
