Question

How does the Number of times nostril open compare to throat moves up and down in a frog?

Answer 1

While completely submerged all of the frog's repiration takes place through the skin. The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels. The thin membranous skin is allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.
A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs.

Answer 2

Hii dear here is your answer


Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in thelungs allowing outside air to flow in. In order to draw air into its mouth the frog lowers thefloor of its mouth, which causes the throat to expand.
