Frogs have a heart that has 3 chambers, and worms do not. Worms exchange gas from their blood through their skin, but frogs are not able to do this. Frogs have the same type of respiratory system as humans.
Their circulartion system is very similar to humans (closed circulatory system)
A frog's circulatory system includes two loops: a pulmonary loop that carries deoxygenated blood from the heart to the lungs for oxygenation, and a systemic loop that delivers oxygenated blood from the heart to the rest of the body.
Animals that breathe using lungs have a pulmonary circulatory system. In this system, the lungs are dependent on the flow of blood from the systemic circulatory system, which works in tandem with the pulmonary system to provide blood flow to these vital organs.
Penguins have a closed circulatory system, which means that their blood is contained and moves through vessels like arteries and veins. This system helps efficiently deliver oxygen to their tissues and remove wastes.
Some dont have any at all but most have closed cirrculatory systems.
