What else can I help you with?
Why do pe teachers instruct those exercising to breathe deeply?
to get the air flowing through your lungs
Explain why the blood flowing to your lung is different from those are flowing out?
Answer:Blood flowing to your lungs is full of carbon dioxide, which gets exchanged in your lungs and the blood flowing out of your lungs is clean/purified with oxygen in it.
What happens when the pumping action of the heart stop?
Then blood will stop flowing around the body and can't carry oxygen to get diffused into the lungs so you die of lack of oxygen.
What function of mucus in the lungs?
the function of the mucus blanket in the lungs is to filter and moisten the air.
What does the alveole do?
Looks like a bubble in the lungs; its function is to exchange gasses between the air inhaled and the blood flowing through the lungs. (Mostly oxygen into blood and CO2 out of the blood.)
Why does exhaled air saturated with water vapour?
Exhaled air is saturated with water vapor because our lungs add moisture to the air as it passes through the respiratory system. This moisture comes from the lining of the lungs and airways, as well as from water that is evaporated from the blood flowing through the lungs.
Why are there four valves in the heart?
2 of these valves (one on each side) stop blood from flowing back into the atria chambers of the heart when the heart is contracting and expelling blood. The other two are there to stop blood flowing out of the ventricles when the heart is filling up with blood. One stops blood flowing through the aorta to supply the body and the other stops it flowing through the pulmonary artery to the lungs.
How bad are your lungs after smoking for 5 years?
your lungs are tired and black but there is still hope if you stop smoking now and breath clean air
Why do you need the brain to live?
The brain controls your body. Without it the heart would stop, your lungs would stop taking in air, etc.
What is the flow of blood between the heart and lungs called?
The flow of blood from the heart to the lungs and back to the heart is called the pulmonary circulation.The blood flowing from the heart to the lungs would be deoxygenated and blood flowing towards the heart from the lungs would be oxygenated.
Why must your seal an open chest wound?
To stop air from entering the chest cavity and collapsing the lungs.
When the lungs are at rest between breathing cycle the air pressure in the lungs is?
Air goes into or out of the lungs due to differential pressure. On inhalation, the pressure within the lungs is below atmospheric, so outside air rushes in. On exhalation, the pressure within the lungs is above atmopheric, so inside air rushes out. When you stop breathing for the moment at the end of exhalation, or when you transition from inhalation to exhalation at the end of inhalation, there is no air flow, because there is no differential pressure. Assuming that you do not close your larynx, then, when the lungs are at rest, the air pressure in the lungs is the same as atmospheric, and this occurs twice in each complete breathing cycle.
