The digestive system organs of a frog are actually very similar to a human's digestive system. They have a stomach, 1 intestine, a liver, a gall bladder, and a rectum.
The frog has a heart that works just like a person's heart. That's how their blood is pumped.
large intestine pancreas stomach spleen small intestine : )
Digestive system includes liver and this has hepatic portal system through which veins pass and come out.
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.
A birds circulatory system consists of two loops.
Digestive System.
Some dont have any at all but most have closed cirrculatory systems.
The pancreas of a frog belongs to the digestive system
The frog's circulatory system, like that of humans, includes the heart and blood vessels. The blood vessels include arteries, veins, and capillaries.
Frogs have a well-built circulatory system that connects to all the other systems in their body. Their arteries circulate blood away from the heart to all the organs, and the veins carry blood back to their unique three chambered heart. The lungs provide oxygen to capillaries, these help oxygen to circulate throughout the body. There are also capillaries, which absorb additional oxygen from the environment, located under the skin. A frogs digestive system along with digestive glands, allows for the breakdown of food. When it reaches the small intestine, it is absorbed into the blood to be transported where needed. Undigested food, urine, and sperm or eggs pass through the large intestine and then into the cloaca, the exit of the digestive, excretory, and reproductive systems. Frogs also have a complex nervous system. This includes a brain, spinal cord and many nerves which help to connect all the systems together and coordinate activity.
2 loops and a heart with 3 chambers
Frogs have 9 organ systems: the integumentary, circulatory, skeletal, digestive, muscular, nervous, respiratory, excretory and the reproductive systems.
Flog gnaw
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.
Humans have teeth up front that are strong and destroy what is being eaten, and they have villi in their small intestines. Frogs have weak teeth that help to crush their food brought into their mouth by their tongue. Their small intestine does most of the digestion.the human digestive system has an anus and an appendix in the digestive system while a frog's digestive system has a cloaca and a cloaca vent
