When the water is spit out again, the cartilage will automatically open again and keep breathing normally. The elephant's nose is very flexible, with open nostrils and finger-like protrusions on the tip of its nose, so it can pick up fine things. They absorb water with their noses, but elephants belong to vertebrates and have a complete oral structure.
The sucked water still needs to be sent to your mouth, so take water through your nose and drink water through your mouth. It is a habit, even a hobby, for elephants to drink water like this. Because elephants drink water through their noses and send it into their mouths, they also use their noses to absorb water and spray it on themselves, because of cooling or bathing.
The esophagus of an elephant is connected with the esophagus. When an elephant breathes, the muscles around the esophageal cartilage relax, the cartilage leaves its original position, and air can enter and exit freely.
So elephants can only hold their breath and drink a mouthful of water at a time, and the extra water will be ejected from their noses by exhaled air, which is why we often see elephants spraying water. Elephants don't drink through their noses. It just sucks water through its nose and sends it to its mouth.
The trachea and esophagus in the elephant's nose are connected together. When cartilage on the trachea absorbs water, the essence will give instructions to let the cartilage cover and open freely, so that the cartilage will not choke when absorbing water!
So it won't choke into the lungs that communicate with the trachea. When it sprays water again, the cartilage will automatically open again and keep breathing normally. This action is very coordinated and accurate.
