Heart has a pacemaker that will continually send a signal. The primary site of the pacemaker is at the sinoatrial node, on the top right atrium. This node will send a signal to atria (which will cause it to contract) and to the atrioventricular node.
Atrioventricular node located between atrium and ventricle. It will send the signal to the ventricle(by the bundle of his) and cause it to contract.

<span>The relative length of frog's small intestine and large intestine related to their functions is because the small intestine helps to absorb calories and nutrients from digested food.
The small intestine needs to be long enough such that it can go through a full digestion. The Large intestine is five feet long and three inch in diameter, while small intestine is twenty feet long and one inch in diameter.
Small intestine and large intestine have a difference in functioning that small intestine its function is to break down food and large intestine its function is to clean out the food which is not absorbed as wastes.</span>
