What process is responsible for transport of oxygen and carbon dioxide across the alveolar membrane?
The process responsible for the transport of oxygen and carbon dioxide across the alveolar membrane is called diffusion. Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli. This process is driven by differences in partial pressures of these gases on either side of the membrane.
Where does the diffusion of oxygen and carbon dioxide occur?
In the lungs, the diffusion of oxygen occurs from the alveoli (air sacs) into the blood capillaries, while the diffusion of carbon dioxide occurs from the blood capillaries into the alveoli for exhalation. This exchange process is facilitated by differences in partial pressures of oxygen and carbon dioxide between the air in the alveoli and the blood in the capillaries.
Which blood vessel does diffusion of oxygen and carbon dioxide take place?
Diffusion of oxygen and carbon dioxide takes place primarily in the capillaries, which are the smallest blood vessels in the body. Capillaries have thin walls that allow for the exchange of these gases between the bloodstream and the surrounding tissues.
How does diffusion move carbon gas?
Diffusion moves carbon gas by the random movement of carbon molecules from an area of high concentration to an area of low concentration to reach equilibrium. This process allows carbon gas to spread and disperse in the surrounding environment through passive transport.
What responsible for the transport of oxygen the body tissues and removal of carbon dioxide?
The respiratory system is responsible for the transport of oxygen to body tissues and the removal of carbon dioxide. This process occurs through the lungs, where oxygen is taken in during inhalation and carbon dioxide is expelled during exhalation. The circulatory system then distributes oxygenated blood throughout the body and collects carbon dioxide to be exhaled.
What type of transport is carbon dioxide passive or active?
Carbon dioxide transport is passive because it moves across cell membranes by simple diffusion, down its concentration gradient. However, in the blood, most carbon dioxide is carried in the form of bicarbonate ions, which is facilitated by specific enzymes and transport proteins.
Oxygen and carbon dioxide are exchanged in the lungs and through all call membrane an active transport b diffusion c filtration d osmosis?
Oxygen and carbon dioxide are exchanged in the lungs through diffusion. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their concentration gradients. This process does not involve active transport, filtration, or osmosis.
What is the four phases of gas exchange in humans?
The four phases of gas exchange in humans are ventilation, pulmonary diffusion, transport of gases in the blood, and systemic diffusion. Ventilation involves the movement of air in and out of the lungs. Pulmonary diffusion is the exchange of oxygen and carbon dioxide between the alveoli and the blood. Transport of gases involves the carriage of oxygen by hemoglobin and carbon dioxide by plasma. Systemic diffusion is the exchange of oxygen and carbon dioxide between the blood and body tissues.

What process is responsible for transport of oxygen and carbon dioxide across the alveolar membrane?
The process responsible for the transport of oxygen and carbon dioxide across the alveolar membrane is called diffusion. Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli. This process is driven by differences in partial pressures of these gases on either side of the membrane.
What passes through a cell using passive transport?
Small uncharged molecules like oxygen and carbon dioxide can pass through a cell using passive transport, which includes processes like diffusion and facilitated diffusion. Water can also pass through a cell membrane through a process known as osmosis.
Why is diffusion?
Diffusion takes away carbon dioxide and unwanted waste from the cells.
What is the process by which carbon dioxide is moved out of the cell?
Diffusion.
How does the carbon dioxide get out of the bloodstream back into his lungs to breathed out?
The carbon dioxide is exhaled.
What is subtance that absobs carbon dioxide?
Carbon dioxide is absorbed through the stomata. The plant uses diffusion to accomplish this.
