The frog's nervous system consists of a brain, a spinal cord, and nerves. Frogs have a highly developed sense of hearing; they can detect high-pitched sounds with their ears and low-pitched sounds through their skin. Moreover, the frogs don't have an external ear like humans do which contributes to maintain body balance. They also have a highly developed sense of sight and smell; its sense of smell is registered by olfactory lobes. These make up the forward portion of the brain. This allows frogs to become aware of predators and prey using their large eyes that project from their head. The eyes are fixed lens, they cannot change its focus. In addition, they have a poorly developed eyelids that do not move. To close its eye, the frog draws the eye into its socket. Frogs also have a keen sense of smell to detect chemical signals that help them identify potential food.
The frog's mouth is where digestion begins. It is equipped with feeble, practically useless teeth. These are present only in the upper jaw. The frog's tongue is highly specialized. Normally, the tip of its tongue is folded backward toward the throat. From this position the frog can flick it out rapidly to grasp any passing prey. To better hold this prey, the tongue is sticky. (See alsoTongue.)
Food passes from the frog's mouth into the stomach by way of the esophagus. From the stomach, the food moves into the small intestine, where most of the digestion occurs. Large digestive glands, the liver and the pancreas, are attached to the digestive system by ducts. A gall bladder is also present (see Digestive System).
Liquid wastes from the kidneys travel by way of the ureters to the urinary bladder. Solid wastes from the large intestine pass into the cloaca. Both liquid and solid waste material leave the body by way of the cloaca and the cloacal vent.
The excretory system of a frog is made up of the kidneys. They are responsible for removing waste materials in the frog's body.
Human and frog digestive systems are very similar. This particular system is conserved across all animal groups in the Kingdom.

A human nervous system is much more complex. Unlike a human a jellyfish does not have a central nervous system.
Difference between a human being and an elephants digestive system?
The difference between salt and msg is that salt is a natural occurring mineral substance and is needed by the human body. MSG is an artificial chemical that causes problems in the nervous system and brain.
they both help you to react in tough situations.
The major difference between the vascular system of a human and a starfish is that humans have cardio vascular system and starfish have water vascular system.
The similarities between the earthworm and human nervous system is that they are carbon based. The difference is that the humans nervous system is skeletal while that of the earthworm is not.
The difference between a human-made system and a "natural" system will depend entirely on what the system is. In many cases the human system will be simpler and have a narrow focus.
