Why does the frog’s heart, which has been removed from the body, continue to contract in saline

Why does the frog’s heart, which has been removed from the body, continue to contract in saline for several hours? 1 excitement periodically occurs in the fibers of the heart muscle? 2 opening valves work in the heart? 3 the fluid of the pericardium moisturizes the heart? 4 cells of the nerve nodes located in the heart muscle contract?

The frog’s heart will contract after being removed in a special solution due to the fact that the impulses that cause the muscle to contract arise on their own. The nerve impulses that make the heart beat are not sent by the brain. The heart rate also cannot be directly influenced by the brain. This applies to both humans and any other animal. When we are experiencing, it is not the brain that makes the heart beat faster, but adrenaline, which is released by the adrenal glands at the command of the brain.
