How does oxygen move?
Oxygen moves through the body via the bloodstream, carried by red blood cells. It is inhaled into the lungs, where it diffuses from the alveoli into the bloodstream, and then transported to tissues and organs where it is exchanged for carbon dioxide to be exhaled.
What is a small opening on the underside of a leaf through which oxygen and carbon dioxide can move?
Stomata.
What structure does oxygen and carbon dioxide move in and out of a leaf through?
Oxygen and carbon dioxide move in and out of a leaf through tiny openings called stomata. Stomata are located on the underside of the leaf and allow for gas exchange between the leaf and the surrounding atmosphere.
Why does oxygen and carbon dioxide move from the alveoli into the blood stream?
Oxygen moves from the alveoli into the bloodstream through diffusion, where it crosses the thin walls of the alveoli and capillaries. Similarly, carbon dioxide moves from the bloodstream into the alveoli for removal when blood with high levels of carbon dioxide comes into contact with alveolar air with lower levels of carbon dioxide.
What substances go into the blood in the exchange at capillaries?
In the exchange at capillaries, substances such as oxygen, carbon dioxide, nutrients (glucose, amino acids), waste products (urea, carbon dioxide), and hormones move into and out of the blood. This exchange occurs to ensure that cells receive the necessary nutrients and get rid of waste products.
What gas moves into or out of cell diffusion?
Oxygen and carbon dioxide move into and out of cells through diffusion. Oxygen diffuses into cells to be used in cellular respiration, while carbon dioxide diffuses out of cells as a waste product of this process.
How do oxygen and carbon dioxide move into and out of cells?
Oxygen enters cells through diffusion, where it moves from areas of high concentration in the bloodstream to low concentration in cells. Carbon dioxide exits cells through the same process, diffusing from high concentration in cells to low concentration in the bloodstream for removal by the lungs.
What sausage-shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of a leaf?
Guard cells control the size of openings (stomata) that allow carbon dioxide and oxygen to move into and out of a leaf. Guard cells change shape to open or close the stomata in response to environmental conditions like light intensity, humidity, and carbon dioxide levels.
What sausage-shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of the leaf?
cardiac cells

What cell control the size of openings that allow carbon dioxide and oxygen to move into and out of the leaf?
cardiac cells
What gases move into or out of our bodies by diffusion?
Oxygen moves into our bodies by diffusion, while carbon dioxide moves out of our bodies by the same process. Oxygen is taken in by our cells for cellular respiration, while carbon dioxide is the waste product produced by this process and is expelled from the body.
What are the hollow spheres of cells within the lungs where oxygen and carbon dioxide are exchanged?
The alveoli are the hollow spheres of cells within the lungs where oxygen and carbon dioxide are exchanged. They are thin-walled, and closely associated with the thin-walled capillaries that surround them. Oxygen and carbon dioxide diffuse across these thin walls to move from the blood to the lungs.
What sausage shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of of a leaf?
The guard cells of a stoma perform this function.

Do the carbon dioxide-oxygen cycle is the pathway in which carbon dioxide and oxygen move through the environment?
no because its online somewhere else
