using diffusion and osmosis.
lungs
No, sweat does not contain oxygen or carbon dioxide. Sweat is primarily composed of water and electrolytes such as sodium and potassium. Oxygen and carbon dioxide are exchanged through the lungs during respiration.
Lungs
The lungs are the organs where the exchange of oxygen and carbon dioxide takes place. This exchange occurs in the alveoli, tiny air sacs within the lungs where oxygen is absorbed into the bloodstream and carbon dioxide is released from the bloodstream.
The respiratory system takes in oxygen through the lungs and removes carbon dioxide and water as waste products during the process of breathing. Oxygen is transported to cells in the body for energy production, while carbon dioxide is expelled from the body through exhalation.
photosynthesis : carbon dioxide + water --> oxygen + glucose this is how plants get the glucose and are "the lungs of the world".
plants do not have lungs. but their leafs absorb carbon dioxide and send out oxygen and their roots take up water.
The blood picks up oxygen from the lungs and releases carbon dioxide in the lungs as well. Oxygen is transported to the tissues where it is needed, while carbon dioxide is carried back to the lungs to be exhaled.
The respiratory system is responsible for taking oxygen into the body and removing carbon dioxide and water vapor. This process occurs through breathing, where oxygen is inhaled into the lungs and carbon dioxide is exhaled out of the body.
We inhale air. Our lungs filter out the needed oxygen which is sent to the tissues of our body. In the process, the lungs get rid of waste by exhaling carbon dioxide.
photosynthesis : carbon dioxide + water --> oxygen + glucose this is how plants get the glucose and are "the lungs of the world".
The lungs largely exhale carbon dioxide and water vapor along with the non-oxygen components of the air taken in (such as nitrogen).
