How do the numerous air sacs that make up the lungs and the numerous filaments that make the gills help the organisms to take in oxygen?

The numerous air sacs that make up the lungs and the numerous filaments that make up the gills have a lot of surface area so they the organisms can take in more oxygen.
I think the term is cell mitosis or cell meiosis, i know that it is Osmosis with water. Essentially the air gets trapped in the sacks and passes through the cell wall into the blood, these sacks are lined with capillaries (thin channels of blood similar to tiny veins) and the chemicals move because the cells create a semipermeable membrane which is essentially a wall which lets things move through in one direction, the air and other chemicals then sift onto the blood to balance the concentration on either side and the cells then actively remove any chemicals they don't want if they can.
an easy example of osmosis would be if you put water with a 25% salt concentration on one side then put water with a 75% salt concentration on the other side (of a permeable membrane) you would end up after a few minutes with 50/50 saltwater on either side.

What do fish breathe using?
Fish breathe through their gills. There are usually gills on either side of the pharynx. Gills have thread-like structures (filaments). These filaments exchange the oxygen and carbon dioxide.

How does gas exchange occurs at the gills of the perch fish?
The gills of a fish are lined with many red, blood-rich capillaries called filaments. As water passes over the gills, oxygen is absorbed out of the water through the filaments into the bloodstream.
Why are gills not suitable for breathing air?
Gills are designed to absorb oxygen only from water, and can only work if water is passing through them or they will collapse. When a fish is taken out of the water, the oxygen-absorbing filaments of the gills flatten out and the fish suffocates because it's gills are not made to absorb oxygen directly from air.The simple answer is that gills colapse when removed from water as they are adapted to water which is more dense than air.
What organisms use gills to breathe oxygen?
A fish! Fish are the only animals with gills and most live in water.
How do most fish get the oxygen they need to survive?
I'm not looking this one up, this is from memory so here goes.Fish generally use gills to get their oxygen and this works by oxygenated water (H2O + extra Os) passing through the fine gill filaments that absorb oxygen from the water supply.
What are fish gills?
Fish breathe with gills. Oxegen is in water. They breathe it in through their gills. They breathe it out through their mouth.
What are two characteristics shared by gills and lungs?
capture oxygen and send it through the body, and organisms use them
Do organisms take oxygen from the air and the water?
Yes organisms take oxygen from the air and aquatic organisms take oxygen from the water using their gills. Some do. Most only from one or the other. For example a tuna fish gets pretty much all its oxygen from oxygen dissolved in water. Humans get all our oxygen from the air. Mudskippers get oxygen from both. Yes. Land animals take in oxygen that plants release using their noses. On the other hand, aquatic or marine animals take in oxygen using their gills.
Through which organ do fish get oxygen?
Those would be the gills. which are composed of many filaments. Gill filaments have rows of thin, vertical lamellae with many capillaries covered by a single layer of cells. Gills are really thin.
Does fish breath with their gills?
Yes. Fish and many other aquatic organisms have gills. The gill is a respiratory organ that extracts dissolved oxygen from water and excretes carbon dioxide.
Why are fish gills feather like rather than smooth?
The gills of a fish appear jagged because they are actually made up of filaments. These filaments increase the surface area that actually makes contact with the water, allowing greater gas and waste exchange with the water flowing through it.
