What would the surface area of all the alveoli in the lungs be in square meters?
Vh
What does pleural surface normal mean?
The pleura is a membrane that surrounds the lungs of mammals. Presumably, the phrase means that the surface of the pleura was found to be normal in an examination.
How does your body adopt surface area to volume ratio to help exchange gases-?
The skin surface is not large enough for big creatures such as humans; therefore we have structures in our lungs that greatly increase the surface area.
How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
Why is surface area of alveoli in lungs is greater than the surface area of the skin?
The surface area of the alveoli is where oxygen and carbon dioxide are exchanged across membranes. A large surface area enables a greater amount of gas transfer. The skin has two main functions: one is holding all our bits in one place and the other is to maintain body temerature. In the latter role, a large surface area is good for cooling the body but bad for keeping warm. So it is a compromise.
Tiny sac within the lungs which increases the respiratory surface?
Alveolar sac and alveoli
What is the human beings largest organ?
lungs
What is the function of alveolar macrophage in the lungs?
function of alveolar macrophagesThe function of alveolar macrophage in the lungs is to remove dust particles and other debris from alveolar spaces. -SheshiAveolar macrophages work to break up surfactanct in the aveoli which exists to decrease surface tension in the lungs. If there is a disorder where the macrophage does not function correctly, such as in PAP, the surfactant will not be broken up and decreased ventilation will occur resulting in less oxygen delivery.
Which of the choices below describes the forces that act to pull the lungs away from the thorax wall and thus collapse the lungs?
the natural tendency for the lungs to recoil and the surface tension of the alveolar fluid
What is 'gaseous exchange'?
Gaseous exchange is the movement of oxygen in the body, it takes place in the lungs through diffusion by the alveolar surface. There are millions of alveloi in the lungs, which gives it around 70m2 of exchange surface.
What substance is made by the lungs to help reduce the surface tension of water in the alveolar?
Pulmonary surfactant...see link for more information.
What is pulmonary alveolar proteinosis?
Pulmonary alveolar proteinosis (PAP) is a rare disease of the lungs.
Surfactant helps to prevent the alveoli from collapsing by what?
Interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar fluid.
What are the most common cells that line the surface of the alveoli and therefore associatedwith the exchange of gases within the lungs?
Type 1 alveolar cells
What is an alveolar dead space?
An alveolar dead space is the volume of air in the alveoli of the lungs which does not partake in gas exchange.
Can human beings live in water as fish do give reasons?
no we cant as we have lungs and fish have gills...
Why do human beings cannot breath inside the water?
There isn't any oxygen to fill your lungs with.
