I believe that the frog heart has one large chamber. When the "dirty" blood returns to the heart from nourishing the body, it mixes with the newly oxygenated blood from when the frog breathed. This type of heart is not as efficient as other animals with chambers to keep the two kinds of blood "dirty" and oxygenated separated. The frog still gets rid of waste gas and pumps fresh gas to its body but some of the waste blood gets pushed around the body too. The frog blood contains a lower concentration of pure gas blood than other animals.
Its part of the skeletal system
The brain and spinal cord of a human are protected by a triple layer of membranes called meninges; the meninges of the frog have only 2 layers. Human brains are more developed that those of amphibians and contain a cerebral cortex which the frog lacks. A human has 30 pairs of spinal nerves, while a frog has only 10.
The integumentary system of a frog has multiple functions. The integumentary system is made up of the skin of a frog, and visually helps to protect the frog - using camouflage. The integumentary system also helps the skin to stay moist when the frog is on land and helps the frog to breathe while underwater.
The axial and appendicular both make up a frog and human's skeletal system. For a frog, the skeletal system's main function is locomotion and maintaining posture. Although the human and frog skeletal system also protect vital organs the frog does not have any ribs whereas a human does. The frog also has less number of vertebrae, extended pelvic bones, and long bones of the hind legs. The frog skeletal system has l59 and the human has 206. The human's skeletal system is a moveable frame and is an efficient factory for producing red blood cells. The frog's skeletal system also produces red blood cell and all their bones are covered with a membrane called the periosteum from which they get their circulation nerves.
It is similar to the function of the gall bladder of a human. They both are used to store the bile, a digestive juice, that is created by the liver. When needed for digestion, the gall bladder secretes a small amount to aid in the breaking down of the food (specifically the emulsification of fats).
It is a set of blood vessels which carry blood towards the heart from the all parts of body.These vessels are called veins.
Yes, 65-70% of the blood volume is in the venous system.
The venous system is responsible for returning deoxygenated blood from the tissues back to the heart. It transports this blood through a network of veins, which have valves to prevent the backflow of blood. The venous system also plays a role in regulating blood volume and pressure in the body.

A frog's liver is in the digestive system
subclavian vein
lymphatic system
Very simply put the venous system, the arterial system and your heart. The venous system bring blood from your organs and extremities to your heart, which pumps it and the arterial system takes it from your heart to your organs and extremities.

The digestive system of the frog feeds into the cloaca. This is how the frog excretes waste from it's system.
Contraction of veins would increase venous return to the right atrium. It would increase the efficiency of the heart pumping.
