Where in your bodies do you maximize surface area?
Nasal cavity tongue surface stomach epithelium length of both intestines kidney's coiled structure of the cochlea lung (alveoli) cerebral cortex capillaries microvilli in small intestines -many more... all i can think of right now
Why are cells spherical instead of cubical if a cube has a larger surface area to volume ratio than a sphere does?
The cells of the body have different sizes, shapes and surface area to volume ratios depending on their function, that is, their structure/function relationships. For example, lung alveolar cells are flat or squamous cells that optimize surface area to volume ratio for gas exchange between blood and the atmosphere; neurons have long tubular axons that increase surface area/volume ratio; cuboidal skin cells of the basal layer are cube shaped and optimally shaped for blood gas and nutrient exchange as well as for their function of adherence and skin replicative function; kidney proximal convoluted tubule cells are cuboid, but extend their membrane surface area for maximal reuptake of blood nutrients by the extension of microvilli on the luminal side of the proximal convoluted tuble. Red blood cells are biconcave discs that, thereby, increase surface area for gas exchange. White blood cells are pretty spherical indicating a requirement for maximizing volume, at the expense of surface area, for antibody production or bacterial destruction etc. . Skeletal muscle cells are long and spindle shaped and often fuse together with other muscle cells in development in order to span the distance across a joint, for example. But you are correct in stating that a cube would have greater surface area to volume ratio than a sphere as a function of length of side or radius (in the case of a sphere).
How much area would your lungs cover if opened up?
________________________________________________________________ that depends on the size of the lung, as it is a little different in each person
How many people are diagnosed with lung cancer in the US each year?
how many people diagnosed with lung canser 2006 how many people are diagnosed with lung cancer in the us 2006
What is the relationship between chest circumference and lung function test?
what is the relationship between chest circumference and lung function test
In terms of surface area which is the largest organ in the human body?
The lung
Would a frog's lung surface area be the same as a human's lung surface area?
In the real life sense no, but if you make our bodies the same size our lungs would be relatively the same size.
How can black lung cancer can affect the respiratory system?
Black Lung disease works by building up coal dust on the surface area of your lungs, therefore reducing the overall surface area of your lungs and reducing the efficency of the lungs.
What is out the sturcture of the lungs?
the lung of most frog and other amphibian are simple balloon-like sturture with gas excange limited to the outer surface area of the lung.
Why is the lung squishy?
The lung has to constantly expand and contract during the exchange of gases. Besides, the alveoli of the lung has to be moist and spongy in order to maximize the surface area to effect the maximum transfer of gases.
Is the human lung sterile?
The healthy human lung is sterile
Do people with lung cancer often need home ventilators?
In lung cancer the effective surface area reduces, leading to breathlessness. Actually human lungs have lot of spare capacity. A person can lead normal life even one lung is completely removed. All the same those who are suffering from extreme condtions are likely to need home ventilator.
Why is the internal surface area of the lungs larger than the surface area of the pleura that surrounds it?
Think of it this way: Scrunch up a paper as tightly as you can and wrap it in as little plastic as you can. Notice that the area of the plastic can be smaller than the area of the paper that it is covering. It is due to the various internal alveoli, which are pouches, that the lung has such a large surface area.
How does the disease affect the respiratory system?
Black Lung disease works by building up coal dust on the surface area of your lungs, therefore reducing the overall surface area of your lungs and reducing the efficency of the lungs.
The total area for gas exchange in the lung is about 10 square meters larger than the entire surface of the body?
FALSE!
Are the walls in our lungs similar to the walls of a ballon?
There really isn't much similarity between a balloon and a lung. The surface of a balloon is smooth...lungs have alveolar sacks that increase the surface area of the lung tissue. This also increases the cross membrane exchange from and to the lung and into the capillaries supplying oxygen and expelling carbon dioxide.
Is the lung sterile?
The healthy human lung is sterile
