What is the concentration of oxygen in the lungs normally compared to carbon dioxide?
The concentration of oxygen in the lungs is higher than the concentration of carbon dioxide. In the alveoli of the lungs, oxygen diffuses into the blood from the air we breathe, while carbon dioxide diffuses out of the blood into the alveoli to be exhaled. This exchange allows for the uptake of oxygen and the removal of carbon dioxide from the body.
Why do lungs work more efficiently than gills in extracting oxygen from air?
Lungs work more efficiently than gills in extracting oxygen from air because they have a larger surface area for gas exchange and a more complex structure that allows for a more efficient transfer of oxygen into the bloodstream. Additionally, the respiratory system in mammals is more adapted to extracting oxygen from the air, which is a richer source of oxygen compared to water.
What organs are found in the thoracic cavity?
There is more than one organ in there... Mainly the heart and lungs, but there are also parts of the digestive tract.
How many cells thick are the walls of alveoli?
It is just one cell thick - or 30 micrometres.
Does the Right lung hold more oxygen?
I would think so. The right lung has three lobes and is larger than the two-lobed left lung, which must make room for the heart. Also, females are generally smaller than males, so their lung capacity is about 20% less, and..believe it or not..taller people generally have longer lungs, so they have more capacity than short people!
Why are sponge lungs better than hollow lungs?
Because they have a greater surface area over which gaseous exchange can take place.
Why does less gas exchange in damage lungs?
less gas exchange damages the lungs because the less Co2 (carbon dioxide) that is let out dameges the body in more ways than explainalbe
Other than gills and lungs what can a amphibian use for gas exchange?
Some lower-order animals can also exchange gases through their skin. Frogs, for instance, when they bury themselves in the mud over the winter.
What do you think would happen when the valves is open if the two lungs were in a single large cavity rather than separate cavities?
If the two lungs were in a single large cavity rather than separate cavities, opening the valves would allow air to flow freely between the lungs without restriction. This would ensure more uniform inflation and deflation of both lungs, leading to improved ventilation and gas exchange in the respiratory system.
Why are the alveoli and bronchi separated in the lungs?
The bronchi are the tubes that actually carry the air to the lungs, they have a different function than the alveoli which function in the process for gas exchange.
What other places in the human body other than the Lungs and Heart is oxygen stored?
Lungs maybe
Why have lungs replaced skin for gaseous exchange?
Lungs have evolved to replace skin for gas exchange because they are more efficient at extracting oxygen from the air and eliminating carbon dioxide from the body. Lungs have a larger surface area, thanks to the branching structure of the respiratory system, allowing for more effective exchange of gases between air and blood. This specialized design enables a higher rate of gas exchange compared to skin, making it better suited for efficient respiration in terrestrial animals.
How do the lungs of an African lungfish work?
The same way as other animals with "lungs". Air is taken into the body and gaseous exchange occurs with the red blood cells. The "lungs" of a lungfish are much simpler in structure than those of a mammal. They are just simple sacs, rather then the spongelike structures of mammal lungs. The general way they work is the same as a mammal's lungs, but they are not as efficient, having a smaller surface area.
Do whales have respiratory organs other than lungs?
no they do not have
What is the heart protected by other than the lungs?
aorta
What covers the airway to the lungs to prevent anything other than air from going into your lungs?
Epiglottis
What other than the heart causes shortness of breath?
Your lungs.
