What two important gases diffuse across the respiratory membrane?
Oxygen and carbon dioxide are the two important gases that diffuse across the respiratory membrane. Oxygen moves from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
Do flatworms have a need for circulatory or respiratory systems?
Flatworms do not have a circulatory system because they are thin enough for nutrients and gases to diffuse directly through their bodies. They also lack a respiratory system as they absorb oxygen and release carbon dioxide through their skin.
what are the gases diffuse at lowest rate?
gases with the higher molar mass
Do humans absorb gases?
Yes, humans can absorb gases through the respiratory system when they breathe in gases present in the air. The gases pass through the lungs and are diffused into the bloodstream where they can be transported to different parts of the body.
How do gases diffuse in and out of plants?
Gases diffuse into and out of plants through small openings on the surface called stomata. These stomata are surrounded by guard cells that can open and close to regulate the exchange of gases such as oxygen and carbon dioxide with the environment. The process of gas exchange is essential for photosynthesis and respiration in plants.
How would thick-walled alveoli affect the exchange of the respiratory gases?
lower exchange rate,takes longer for gases to diffuse

Why do gas exchange surfaces need to be moist?
The gases are to dissolve and diffuse through.
How does the circulator systems work with the respirator systems to get oxygen into the blood?
At the respiratory surface gases diffuse into or out of the blood depending on the pressure gradient.
How do insects respire?
Insect respiratory system uses a system of internal tubes and sacs through which gases either diffuse or are actively pumped, delivering oxygen directly to tissues that need it via their trachea.
Does all gases diffuse the same speed?
No, all gases do not diffuse at the same speed. Factors such as molecular weight, temperature, and pressure influence the diffusion rate of gases. Lighter gases tend to diffuse faster than heavier gases.
Gases diffuse most efficiently across a respiratory membrane if the membrane is?
thin and moist, with a large surface area and a large concentration gradient.
The exchange of respiratory gases in a cell takes place through the?
the lungs
Why does single celled organism not necessarily need a respiratory system?
Nutrients and gases can diffuse directly across the cell membrane, thereby eliminating a need for such a complex system. #hopeihelped :)
