Study Notes
Respiratory System
- The human respiratory system's primary function is gas exchange, taking in oxygen and expelling carbon dioxide.
- The respiratory system is composed of the lungs, which are responsible for gas exchange during breathing.
- The human respiratory system is made up of a conduction zone and a respiratory zone.
- The respiratory zone is found deep inside the lungs and is responsible for gas exchange.
- The respiratory system is essential for life. Without oxygen, brain cells begin dying after only five minutes, leading to brain damage and death.
- Oxygen is transported from the lungs to the heart, and then pumped to the cells via the cardiovascular system. The cells use oxygen to obtain energy and release carbon dioxide as waste.
- The exchange of gases occurs in the lungs (external respiration) and in the cells (internal respiration).
Frog Respiratory System
- Frogs use a combination of lung and skin respiration for gas exchange.
- The frog's respiratory system includes lungs, skin, and mouth/throat.
- The frog's lungs are simple sacs with a small surface area compared to human lungs.
- Frogs can breathe through their skin, which is moist and permeable to gases.
- Frogs also use their mouth/throat as a pump to force air into their lungs, and expel it using a combination of pressure changes.
- Frogs use a gular pump to increase the volume of their throat, drawing air into the lungs, and then closing the glottis and forcing air out of the lungs.
- Frogs can also use a buccal pump, expanding and contracting the floor of their mouth to pump air into their lungs.
- The buccal pump is the primary method of inflating the lungs in amphibians.
Differences between Human and Frog Respiration
- Humans primarily breathe through their lungs, with a complex system of airways and alveoli designed for efficient gas exchange.
- Frogs can breathe through their skin, mouth/throat, and lungs, but their lungs are not as developed as human lungs.
- Humans use a diaphragm and intercostal muscles to expand the lungs, while frogs rely on pressure changes in their mouth/throat to force air into their lungs.
- Human breathing is controlled by the nervous system, while frog breathing is more instinctual and often relies on their environment.
Assessment
