What three important physical features does the gas exchange membrane in the lungs need to have to be efficient?
O2 and CO2 are carried by the blood.
Gases moves by diffusion that is, they move from an area of higher concentration to an area of lower concentration.
The lining of the alveoli most be moist to help gases diffuse.
1. Thin and permeable exterior:To let gases through
2: Moist: To alow gases to be in solution
3. Large surface area: for efficient and fast exchange

What is believed to be responsible for the rapid water exchange in plant cells?
Aquaporins, which are specialized proteins in the cell membrane, are believed to be responsible for the rapid water exchange in plant cells. These proteins facilitate the movement of water molecules across the membrane, allowing for efficient water transport within the cell.
Why are gills efficient organs for gas exchange in water-dwelling organisms?
Gills have a large surface area covered by thin, moist membranes that are highly vascularized, allowing for efficient exchange of gases (oxygen and carbon dioxide) between water and a fish's bloodstream. The gill's structure and counter-current flow system in fish enhances the exchange of gases by maintaining a steep concentration gradient across the respiratory membrane, facilitating efficient gas exchange.
What is the thin barrier that allows for the efficient exchange of gases between the lungs and the blood called?
The thin barrier that allows for the efficient exchange of gases between the lungs and the blood is called the respiratory membrane. It consists of the alveolar walls, capillary walls, and their basement membranes. This structure is essential for the diffusion of oxygen and carbon dioxide during respiration.
Large cells work better if they?
have a lower surface area-to-volume ratio, allowing for efficient exchange of nutrients and waste products through the cell membrane.
One of the most important functions of the cell membrane is to the movement of dissolved from the liquid on one side of the membrane to the liquid on the other?
One of the most important functions of the cell membrane is to regulate the movement of dissolved substances (such as ions and nutrients) across the membrane. This selective permeability helps maintain internal cellular conditions and control the exchange of molecules with the external environment.
What happens at the respiratory membrane?
gas exchange
What happens if the surface area of the respiratory membrane decrease in gas exchange?
A decrease in the surface area of the respiratory membrane will result in a decrease in gas exchange.
What has the author Hui Li written?
Hui Li has written: 'Proton exchange membrane fuel cells' -- subject(s): Proton exchange membrane fuel cells
What organelle has two subparts?
The mitochondria is an organelle that has two subparts: the outer membrane and the inner membrane. The inner membrane is highly folded into structures called cristae, which are important for increasing surface area to allow for more efficient ATP production.
What type of plasma membrane transport is used for exchange?
Diffusion
What is the name of the process by which gaseous exchange occurs at the AC membrane?
The process by which gaseous exchange occurs at the alveolar-capillary membrane is called external respiration. This involves the exchange of oxygen and carbon dioxide between the alveoli in the lungs and the blood capillaries surrounding them.
What is exchange between plasma and interstitial fluid compartments that takes place across the capillary membrane?
gas exchange
