frog does not have ribs. It does not have rib cage also, so frogs cannot breathe by expanding the rib cage
Some dont have any at all but most have closed cirrculatory systems.
The frog's circulatory system, like that of humans, includes the heart and blood vessels. The blood vessels include arteries, veins, and capillaries.
2 loops and a heart with 3 chambers
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.
Frogs have a double circulatory system, which means that circulation goes from the heart to the lungs (where it becomes oxygenated), then returns to the heart, then is pumped to the rest of the body (which takes the oxygen), and then returns to the heart. They have a closed circulatory system, which means that the blood travels through the body in vessels. Frogs have a three-chambered heart.
The need for a powerful heart and greater energy expenditure are both disadvantages of a closed circulatory system. Even with its disadvantages, a closed circulatory system is much more efficient than an open one.
Frogs have 9 organ systems: the integumentary, circulatory, skeletal, digestive, muscular, nervous, respiratory, excretory and the reproductive systems.
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.
single loop and heart with two chambers, like that of a fish.
closed circulatory system (double circulatory system)
Well.... The frog needs nutrients in order to survive. When the frog would eat its food, the food would go down through the digestive system, where obviously the food would break down. Then the circulatory system would take the broken down food and spread the nutrients that were taken from the food, all across the frogs body. So the main answer is that a frogs digestive and circulatory system are important for its survival because the frog needs nutrient given to its body. The two systems work together to break down the food and spread the nutrients across the frogs body. - This was the way I answered a question on my lab.
They're both the circulatory system.
