Why do the lungs need a large surface area?

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 ( Full Answer )

How large is the surface area of your lungs?

\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.

Why should skis have a large surface area?

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.

Why do gills have a large surface area?

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

Why do the alveoli have a large surface area?

"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 ( Full Answer )

How is the alveolar surface area so large?

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 ( Full Answer )

How can the surface area-to-volume and surface area-to-mass ratios be increased in a large cell?

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 ( Full Answer )

Why do plants need to have a large surface area?

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 ( Full Answer )

Why do some organelles need large surface area?

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.

Do leafs have a large surface area or a small one?

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.

How does the kidney achieve a large surface area?

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 )

How is a large surface area achieved in the respiratory system?

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.

Why do you need a large surface area in gas exchange?

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.

Why do alveoli need a large surface area?

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.

Why do alveoli provide a large surface area?

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 ( Full Answer )

Why is a large surface area necessary for the alveoli in the lungs?

According to fick's law rate of diffusion =(proportional to)= Surface area x Diffusion gradient Diffusion Pathway thickness So for a sufficient rate of diffusion, Surface area must be large The diffusion pathway is already at it's minimun of 1 cell thick and the gradient is harder to a ( Full Answer )

What is significant about the large surface area of gas exchange surfaces?

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 ( Full Answer )

Why alveoli in the lungs have large surface area and many blood capillaries surrounding the?

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 ( Full Answer )

Why does the small intestine have a large internal surface area and what contributes?

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. ( Full Answer )

Why do gills have a large surface area and are rich in blood?

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

What can large cells do that will increase their total surface area to volume ratio?

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 ( Full Answer )

Why do snow skis have a large surface area considering particle theory?

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 ( Full Answer )

How do lungs have such a large surface area?

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 ( Full Answer )
