Why respiratory surface of all organism must be moist?
Because alveoli have to be able to exchange gases freely like oxygen and get rid of carbon dioxide. Also, oxygen must have moisture to benefit breathing.
What is required in all living things in order for gas exchange to occur?
In any living organism that needs to breath, the only thing consistently required for life is the presence of moist membranes. The movement of oxygen and carbon dioxide across the membranes between the environment and the respiratory surface occurs by diffusion. Respiratory surfaces are generally thin and, since living animal cells must be wet in order to maintain their plasma membranes, these respiratory surfaces must be moist.
What tissue is found all over your body?
Epithelial tissue is found all over the body, covering organs and lining body surfaces to protect and allow the exchange of substances.
Why is Jupiter the gaseous planet?
Jupiter is considered a gaseous planet because its composition is primarily made up of hydrogen and helium gases. Its large size and strong gravity prevent the formation of solid surfaces like those found on terrestrial planets. Jupiter's composition and structure make it distinctly different from rocky planets like Earth.
Is Uranus a soild surface or gaseous plant?
Uranus is a gaseous planet, composed mainly of hydrogen and helium, with no solid surface like Earth. It is classified as an ice giant due to its composition of water, ammonia, and methane ices in its atmosphere.

Where in the body apart from the lungs does gaseous exchange occurs?
Gaseous exchange occurs through capillaries all over the body to bring oxygen to cells and remove carbon dioxide.

Why must all respiratory system have a large surface area over which air can pass?
You have barile? Lungs have hierarchical structure which minimizes volume but maximises surface area Aveoli are the smallest units of structure and are the site of gaseous exchange: - They are circular = max surface area for min volume - Their most surfaces faciliate the exchange of gases - They have extensive blood supply which also faciliate the exchange
List four requirements for all respiratory surfaces?
The structure of organs is always relevant to function. The function of respiratory surfaces is gaseous exchange. The structure would therefore facilitate this as follows: 1. A single layer of squamous epithelial cells. 2. A large blood supply to the surface. 3. A large surface area. 4. Counter-current flow of medium to blood. (This means that the blood and air/water are flowing in opposite directions so as to increase the concentration gradient).
Explain why large active organisms need special surface for exchange?
large organisms need larger area to exchange more substances.but large organisms have small surface area to volume ratio.this means that the surface is not large enough to enable gases and nutrients at the fast rate needed to keep all the cells alive.thus large organisms need special exchange surfaces to provide the body with the nutrients and gaseous exchange they require.
What is about the alveolus that makes gaseous exchange occur efficiently in the lungs?
Small volume and (relatively) large surface area. One estimate of the total surface area of all your alveoli is the area of a tennis court. (all folded up into your chest.) Also, only two layers of cells (and some interstitial fluid) between blood and air. Moist surface Close proximity to capillaries
Which gaseous element with the highest density of all gaseous elements?
Radon is the densest gaseous element.
Can a liquid substance diffuse in another liquid substance a gaseous in liquid a gaseous in gaseous?
Yes, all of them.
What part of lungs are affected by smoking?
Lungs get coated with soot, which reduces their ability to act as an exchange barrier, making breathing and gaseous exchange harder.
What tissue is found all over your body?
Epithelial tissue is found all over the body, covering organs and lining body surfaces to protect and allow the exchange of substances.
How are all outer planets similar to each other?
All outer planets in our solar system are gas giants, made up mostly of hydrogen and helium. They have thick atmospheres and lack solid surfaces. Additionally, they all have ring systems and multiple moons.
