The respiratory system and the circulatory system are involved in gas exchange. The respiratory system allows for the exchange of oxygen and carbon dioxide in the lungs, while the circulatory system transports these gases between the lungs and the rest of the body's tissues.
Amphibians, such as frogs and salamanders, are able to exchange oxygen and carbon dioxide through their skin. Their skin is thin, moist, and highly vascularized, allowing for this gas exchange to occur.
Without getting into the gas exchange issue, amphibians start out life as eggs and larvae in the water. As they mature into adulthood they break free from the water and crawl onto dry land.
Amphibians.. because they exchange gas partly through their skin, so gases must be able to move in and out - Their skin's got to be permeable and moist.
Having the gas exchange organ inside the body allows for more efficient exchange of gases with the environment by minimizing exposure to external factors such as temperature and humidity. This internal placement also provides protection against physical damage and reduces the risk of desiccation. Additionally, it allows for more precise regulation of gas exchange processes.
the organ that is involved in gas exchange is the lung. the specific lung structure that is the site for gas exchange is the alveolus which is part of the alveoli, which is found in the lung.
The organ that has alveoli wrapped in capillaries for gas exchange is the lungs. Alveoli are tiny air sacs where oxygen from inhaled air diffuses into the bloodstream, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. This efficient gas exchange process is facilitated by the close proximity of the alveoli to the surrounding capillaries.
Because that is where the primary gas exchange happens.
