Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
Oxygen must diffuse through the cell membranes of the alveoli in the lungs. This diffusion depends upon the concentration gradient between the air in the lungs and the dissolved oxygen in the blood moving through the lung tissue. Air is only about 20% oxygen, so in order to load up the blood with ox…ygen, there must be lots of surface area for diffusion from the air. . To allow for huge amounts of oxygenated blood be diffused from the alveoli to a capillary network. and for CO2 to travel form the blood capillary network into the alveoli. The surface area is huge because massive amounts of O2 and CO2 are diffused each minute= around 6- 10 liters. Whilst exercising you can use around 100 liters of oxygen per minute. . Human lungs have a large surface area so that gas exchange can take place more efficiently and effectively. Carbon dioxide must come out of the blood and into the inspired air while oxygen must be absorbed by the blood from that air. A larger surface area means more area (more places) for gas exchange to take place. Alveoli in the lungs increase the overall surface area of the lungs, to encourage more diffusion to take place, so that a greater volume of oxygen / carbon dioxide can be transferred out of / into the lungs. it need room for oxygen to travel in an out.

It is important that the gills of a crayfish give them a largesurface area because it helps the crayfish to breathe. The biggerthe surface area, the more oxygen in the crayfishes system.Ã
\nIn an average adult with healthy lungs we find approximately 300 million alveoli with a total surface area approaching 150 meters square, or the size of a tennis court. 70m2 The edzact size of a tennis court xxx Typically between 50 and 100 square meters 160 meters squared.
I believe it has something to do with the large surface area resulting in lower pressure on the snow (or whatever your skiing on, if not snow) so you don't fall into the snow.
To acquire more oxygen from water as the large SA of the gills allow more water to pass through and thus more O2 from the water to transfer into the gill-bearing creature's bloodstream for respiration
The name given to a large area of level land on the Earth's surfaceis a plateau. A plateau also typically is elevated above thesurrounding area. Such areas are also sometimes called tablelands.
"Gas exchange is by diffusion from the gas contents in the lungs to the blood vessels in the pulmonary aveolus. The many indentations within the lung act to increase the surface area in the volume occupied by the lungs." To improve on the previous answer, the larger the surface area compared to th…e volume (or size) of the cell, the faster the rate of diffusion through the cell membrane. So with a larger surface area, more particles can diffuse in and out of the cell and at a faster rate for the same volume of cell. ( Full Answer )
There are millions of alveoli in the lungs they provide a very large surface area why is a large surface area necessary?
By having millions of these tiny sacs, the surface area of the lungs is vastly increased. This adaprtation enables a greater volume of air to breathed in, in each breath. An increased surface area allows for more diffusion to take place between the lungs and the blood.
The alveoli are tiny little sacs with walls only one cell thick, and they fill all but the conducting portion of the lungs. Think about a single balloon filled with 1 liter of air. Now take 4 small balloons and fill them each with 250mL of air. The same amount of space will be taken up by the 4 s…maller balloons as the 1 larger balloon, i.e. 1L, but the 4 smaller balloons have much greater surface area for gas diffusion. ( Full Answer )
By adding elongated extensions to the cell the surface area tovolume ratio will be increased. One good example of a type of cellthat can get very large but still have adequate oxygen diffusionrates is a neuron, some of which can have meters long axons in someanimals. Flatten it. The shape should be …as far from spherical, and the cross section as far from circular as possible. ( Full Answer )
Plants get their chemical energy from a process know as photosynthesis. In order for this to work, plants need sunlight (ie they die if left in darkness) To maximize the amount of light they can absorb in their leaves, they must have a big surface area. Notice the sterm is often cylindric in sha…pe, minimalizing the surface area in order to avoid vaporizing of precious water and to avoid falling over in storms. ( Full Answer )
Gills are the underwater equivalent of our lungs and they need those features in order to extract enough oxygen from the water so that they can breath.
It has a large surface area so it can absorb the maximum amount of sunlight.
A large surface area is required for some organelles to absorb proper nutrition and then move to another area to digest and then expel waste. The large surface area would not be visible on most microscopes.
To effectively radiate heat. If they had small surface areas the desired radiation would not occur.
the surface area of LEAVES depends. Pine needles and cacti have small surface areas banana leaves, philodendron leaves, and other tropical plants have gigantic ones. it all depends on where the plants are endemic to.
Tiny sacs that line the ends if our bronchioles, called alveoli . By enlarging the surface area-to-volume ratio, a greater volume of gases can be exchanged in the lungs.
The cells lining the proximal tubules of the nephrons have a highlyfolded cell membrane on the lumen side of the tubule made ofmicrovilli. This is referred to as a brush border and is importantin increasing the surface area for reabsorption of components ofthe filtrate as it passes down the nephron.… ( Full Answer )
In a small intestine for example, the greater surface area allows the villi to get more food for digestion.
Inside each lung are millions of tiny sacs, called alveoli. These structures greatly increase the surface area of the lungs, which helps to maximise the volume of oxygen and carbon dioxide that diffuses to and from the lungs.
The large surface area of the small intestine is achieved by a combination of anatomical features such as the plicae circularis, the vili, and the microvilli.
The larger the surface area, the more heat that can be drawn away from the engine allowing it to stay cooler.
A larger surface area allows for more chlorophyll to be in the leaf structure. This in turn allows for a more efficient way of capturing light in a low light environment.
To allow for the quickest changing of gas. If you only had a small space the size a pinhole, it would take much longer then if you had a larger surface area to allow for that change.
The lungs have an extensive surface area, measuring around 30-50square meters. This is in large part due to alveoli, which aresmaller structures within each lobe of the lung.
Plant gets water in the form of moisture around soil particle,which is very scarce. So tn increase efficiency,it needs large surface area.
Why does the small intestine have a large internal surface area and what contributes to this surface area?
The small intestine needs a large internal surface area because that is how it absorbs the nutrients in food.
To better aid in the critical job of gas exchange. That is also whythey utilize simple squamous as their preferred cell type Lesscells to go through to exchange Oxygen and carbon dioxide.
the root hairs attached to the root give the root cell a large surface area so that they can take minerals and water in more efficiently
Which will dissolve faster a substance with little surface area or the one with a large surface area?
One with a large surface area because the solvent will be able to dissolve more solute simultaneously.
The function of alveuli is to provide a surface for gas exchange. Therefore, a large surface area means that there is a lot of area for the gas exchange to take place. Therefore it is to improve efficiency of gas exchange in the lungs (exchanging carbon dioxide for oxygen). The large surface area i…s due to the shape of the alveoli- the have many small "pockets".

There are around 600 million alveoli in the lungs that have a cummulitive surface area of around 70m 2 . ( Full Answer )
it will not be able to take in enough nutrients or get rid of wastes
Gas molecules need to stick to a spot on the surface, inside or outside, for an exchange to occur. If a spot is already occupied, then the available surface area is smaller by one spot and its immediate surrounding (molecules of the same gas repel each other slightly, in general). Even if the spot i…s occupied with the right gas molecule on the outside, the inside spot may not be occupied with the correct counterpart. A larger surface area allows a better chance of the right molecules occupying opposite sides of the surface for an exchange to occur. ( Full Answer )
Having a large surface area to volume ratio allows root hairs to quickly absorb water and nutrients from the soil.
The alveoli provide large surface area for the exchange of gasesbetween the blood and the air. Each alvoeli is surrounded by manycapillaries(tiny blood vessels). The very thin walls and largesurface area of the alveoli and numerous capillaries surroundingthem enable gases to be exchanged quickly and… efficiently. Oxygenin the inhaled air diffuses from the alveoli to the blood in thecapillaries. The blook then carries the oxygen to the cells in theother parts of the body. The waste product of respiration, CO2 ,diffuses from the blood to the lungs through the capillariessurrounding alveoli. It leaves the body through bronchi and tracheawhen you exhale( breathe out).

the small intestine has a large surface area because it allows nutrients to be absorbed into the body more quickly and easily.If there was a small surface area may-be most of our nutrients would end uo in the large intestine and out when we go to the toilet. To answer the final part of the question.… What contributes? the length and elasticity of the small intestine contributes to it having a large surface area. ( Full Answer )
The larger the surface area, the more space it has to absorb nutrients from the food you eat.
because in many organisms like fish etc it is an organ for respiration the gills are supplied with capillaries so that the oxygen absorbed can diffuse into the blood it has large surface area so that more oxygen can be diffused in and more co2 can be removed
They can't really. That's the problem and that is why cells are so small. As they increase in size, their surface area to volume ratio gets smaller, so they do not have enough surface area to support their volume. Now, if we picture something like a small intestine that has lots of projections or so…mething like the mitochondria where there are lots and lots of folds to increase surface area then I suppose cells could do this as well to increase surface area. However it has always been explained to me that cells divide when then surface area gets to be too big (and also to make new cells for growth and repair). ( Full Answer )
The plants in the shade develop larger leaves to capture more sunlight but at the same time it invites for more transpiration from larger leaf surface, hence it is an adventure for such plants.
Particle theory concerns very small particles and relates only indirectly to large objects such as snow skis. Although it is perfectly true that both the snow, and the snow skis are composed of large numbers of tiny particles, those particles create electromagnetic fields, and the merged fields act …like continuous surfaces. The solidity of solid matter is the result of electrons repelling each other, and nothing more than that. Since electrons are on the outside of atoms, and protons are on the inside, when you get close enough to any atom the negative charge predominates, hence, at a sufficiently close range, atomic matter repels other atomic matter (like charges repel, so negative charges repel other negative charges), hence, solid matter does not interpenetrate other solid matter, which is why it is solid.

Lungs have large interior surface area because they're not justbig bags. On the inside, they're full of a spongy network ofsmaller, smaller, and ever-smaller air passage-ways, ending in tinydead-end sacs called alveoli. Every tube, sac, detour, fork in theroad, branch, split-off, and tiny dead-end h…as walls with surfacearea. . The speed at which oxygen can be transferred into the bloodstream depends on the collective surface area of the alveolicontained in the lung. That is why we have alveoli, filling thelungs like a sponge. We need the oxygen collected by thebloodstream in order to burn the energy that our body has stored,and a faster input of oxygen allows a faster burning of that energy- hence the advantage of having that maximized surface area. . One common result of many years' smoking is that the wallbetween two adjacent passage-ways shrivels up and disappears, andthose two passageways merge and become one. That reduces thesurface area in that tiny part of the lung. When it progresses tothousands of tiny parts of the lung, you start to notice it ...you're short of breath, because the interior surface area of yourlung is reduced, and you can't grab enough of the oxygen from theair you take in. That's the condition called 'emphysema'. ( Full Answer )
The surface must get more spherical. When it reaches a perfect sphere the surface area cannot be reduced without also reducing the volume.
Many folds and tiny microvilli line the small intestine. The microvilli are like tiny fingers and these help increase the surface area.
Your lungs have very large surface area. About 100 square meters or 1100 square feet.
Large dark areas on the Moon are called "maria", Latin for "seas", because the ancients who observed the Moon with the naked eye thought that they resembled the seas that they were familiar with.
Your small intestine has very large surface area to absorb the digested food material. The surface area of the small intestine is 2750 square feet. Much more than you can imagine.
