Is there a difference between either the digestive system, endocrine system, nervous system, muscular system or the skeletal system between the both. With either the following systems...and if so which one? Like I'm speaking physioloigcally and atonomical.

One of the major differences is in the circulatory system, because frogs are amphibians, and have a three-chambered heart. There is some mixing of oxygenated and deoxygenated blood, so it is less efficient than the four-chambered heart of the mammals (like a horse).
Another difference is in the digestive system: horses are herbivores, and eat primarily grass or hay. Frogs, however, mostly eat insects.

There are of course differences in all those systems.
The horse is a herbivore, specifically a grass eater. Grass is low in nutrition, especially considering that mammals cannot digest cellulose, the main carbohydrate in grass. Fortunately, the horse has a very long intestinal system, giving it a chance to process and absorb nutrients.
Between the small and large intestines there is a big pouch called the cecum, of which the appendix seems to be the vestige in humans. This contains oodles of cellulose- digesting bacteria. They not only break the cellulose into starches and sugars, but also provide protein for the horse's diet. The horse has to eat a lot of this low-nutrition food to maintain itself, and excretes a large amount of waste as well.
The cecum can be a source of serious digestive colic in horses; they can die from it. (Humans too can have problems with the appendix, though it doesn't do much if anything.)
Frogs eat bugs, which are high in protein and high in nutrition; thus the chemicals in the stomach are crucial to digestion of proteins. Frogs have minimal teeth, since protein doesn't require much chewing; besides, frogs eat insects whole rather than biting off pieces. Horses have powerful incisors for biting and molars for grinding.
Horses have a urinary bladder for holding urine, which is excreted through the urethra, while solid waste is excreted from the large intestine through the rectum and anus. In the frog, the urine and solid waste are excreted together from the cloaca through the vent. Frogs excrete mushy waste, while horses excrete balls of poop.

frogs because peacocks look nice but they make that annoying noise and horse are expensive and can squish you
