The respiratory system is there so you can breath air in and exhale out. When you breath in your breathing in air, but what your really breathing out when you exhale is carbon dioxide. So what your respiratory system does is it takes in clean air and disposes the carbon dioxide from your lungs.

The most important gases in air are oxygen, nitrogen, argon helium krypton
Air pressure relates to weather conditions, and weather was very important to farmers.
Sudden change in air pressure might lead to death. Sudden change in air pressure will disrupt the blood and air circulation within your body. You might feel dizzy and have nose-bleeding in such cases.
That would be "bleeding" the system.
Bleeding
By bleeding the coolant system.
By bleeding the brakes.
Air in the cooling system. Look up bleeding cooling system.
Brake system bleeding is working on hydraulic brake systems. This is when the brake line has air bubbles in the line. You open the bleed screw on the caliper and pump fluid through the lines until all of th bubbles are gone from the system, an air bubble will steal pressure from the brake system and prevent good operation.
Start by bleeding the cooling system of air. Google is your friend.
This can vary, gravity bleeding takes longer, but only requires one person to do the job. If you are manually bleeding you can generally tell which lines have the most air in them. Manual bleeding can be faster than gravity bleeding. Whether you are manually or gravity bleeding it all depends on how much air is in the system and to make sure you have a solid pedal before driving!
When a high pressure brake line or power steering line is disconnected near the pistons or any where besides reservoir. air may get into the system. the only way to get the air out of the system is by bleeding system, or purging system. if not done the result will be spongy brake's squealing and whining sounds when turning.
more than likely an air lock on your water system it will need bleeding to release the air lock if that fails try replacing the thermostat
Bleeding a sprinkler system involves draining the existing water from the pipes. Afterwards, the pipes should be completely dried by using an air compressor.
Brake bleeding is technique used on a hydraulic brake system in order to purge the brake lines of any air bubbles. Removing air bubbles allows for the brake system to function properly.
