Study Notes
Cutaneous Respiration
- Gas exchange occurs through the skin, allowing for the exchange of oxygen and carbon dioxide directly between the environment and the body's internal tissues.
Characteristics of Cutaneous Respiration
- Cutaneous respiration occurs in animals that have a moist, permeable skin that allows for the exchange of gases.
Examples of Cutaneous Respiration
- Amphibians, such as frogs and toads, exhibit cutaneous respiration.
Advantages of Cutaneous Respiration
- An advantage of cutaneous respiration is that it allows for the exchange of gases without the need for specialized respiratory structures, such as lungs.
Environmental Factors Affecting Cutaneous Respiration
- Environmental changes, such as changes in temperature, humidity, and oxygen levels, can affect the rate of cutaneous respiration.
Evolutionary Adaptations
- Animals relying on cutaneous respiration do not need specialized respiratory structures because their skin is adapted to facilitate gas exchange.
