Lungs

no one knows, this is a very stupid question, why do you need to know this??

The bronchi (their bronchioles) end in the air sacs (alveoli). These are where oxygen enters the blood vessels, and carbon dioxide is removed.

Using your muscles to voluntarily force the diaphragm lower into the abdomen will cause air to be drawn into the lungs. Lowering the lung pressure in this way is the only way to expand your own lungs. It is possible to expand them using compressed air, as with a ventilator or CPAP device (continuous positive airway pressure).

why doo we sneeze

The answer to that would be Cancer

Hyaline cartilage, which also covers the ends of bones at the joints, which reduces friction during movement.

cystic fibrosis

Bronchi are in the lungs. Off the two bronchi branches are broncioles and off of those are alveoli which take in the oxygen

Pleurodynia

No. The skin does.

The lungs and respiratory system allow oxygen in the air to be taken into the body. The lungs' main function is to help oxygen from the air we breathe enter red blood cells. Red blood cells then carry oxygen around the body to be used in the cells found in our organs and tissues such as the lungs.

The pleura is a slick, wet, shiny membrane. It is the outer most layer of tissue surrounding the lungs and also the inner most layer of tissue coating the chest wall. The pleura provide well lubricated surfaces of the chest wall and lungs to contact each other with minimal friction during respiration.

The word cancer is the Latin for crab.

The Tropic of Cancer is so called because the sun was in the constellation of Cancer when it appeared directly overhead at this latitude during the summer solstice.

The function of the respiratory system is to exchange oxygen and carbon dioxide. You breath in air that is rich in oxygen and your lungs move it into the blood to go throughout your body. Then your lungs extract carbon dioxide from the blood and you breath it out.

Carbon dioxide (CO2) is a harmful waste material that leaves the blood and travels though the lungs before leaving the body.

Of course they do.

Most land vertebrates including all birds, mammals, and reptiles have lungs. Most amphibians have lungs as well, though some salamanders breathe through their skin or through gills. A few types of fish have lungs as well

Spiders and gastropods and among the few invertebrates to have lungs. Most breather passively through spiracles, their skin, or through gills.

The alveoli.
The Respiratory System

Respiratory system

Your lungs take in the oxygen that you breathe and takes the oxygen around your body with red blood cells through the veins and arteries.

They pump air into your blood which goes around you body to kill bacteria/virus, give cells nutrients, and heal wounds. If your lungs are destroyed or you don't breath then you would die usually.

To allow passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae.

diffusion - the natural movement of particles from high to low density. oxygen dissolves in a film of liquid water lining the alveoli (tiny air sacs in the lungs) and the wall of the alveoli and wall of the capillary (each 1 cell thick) into the blood in the capillary. the oxygen is moving from the high concentration of oxygen in the lung to the low concentration of oxygen in the blood. this low concentration is maintained in the blood since it continuously flows away and is replaced by oxygen poor blood. the high concentration of oxygen in the lungs is of course maintained by breathing in fresh air.

The air inside the lungs is never replaced completely. 1500 ml of air is always present in the lungs. Therefore,gaseous exchange continues in the lungs even during expiration .

By doing sport, you will most likely get increased lung capasity.

Just do not overdo it.

There is no quick way to get increased capacity.

Overworked lungs might be damaged and create scartissue of which will reduce capasity instead.

Bronchi is branched in primary and secondary. bronchi is branch of bronchus.
