Study Notes
Circulatory System of Frog
- Frogs possess a double-looped circulatory system that includes a 3-chambered heart.
- Adaptations for terrestrial life enable frogs to pump blood against gravity.
Blood Flow Process
- Deoxygenated blood returns from the body to the heart's Right Atrium.
- Blood moves from the Right Atrium to the ventricles of the heart.
- Blood is pumped to the lungs, where it becomes oxygenated.
- Oxygenated blood returns to the Left Atrium of the heart.
- Blood is then pumped from the Left Atrium to the body through the ventricle.
Respiratory System
- Frogs utilize positive pressure breathing to inflate their lungs by pushing air in.
- The respiratory system is supported by both lungs and moist skin, facilitating gas exchange.
