Before the invention of automobiles and airplanes, there was only one way to cross the deserts of Asia and Africa: by camel. That is why the camel was called the "ship of the desert". Of all the adaptations that enable the camel to live and travel in the desert, the most important is the hump on its back. When the hump empties, it loses its shape and begins to hang from the camel's back in flabby folds. There are no bones in the hump, it is made up of fat and muscle. The purpose of the hump is to serve as a kind of food storage. Many days before the start of the journey, the owner of the camel forces him to eat and drink as much as possible. The camel is eating off, and its fat hump, weighing about forty-five kilograms, sticks upright on its back. This store of fat can sustain a camel for several days if it cannot find food for itself along the way. On the road, a camel can also make do with its internal water supply. Before starting the journey, the driver forces him to drink about fifty liters of water. He achieves this by giving the camel salt and making it very thirsty. A camel has three stomachs. In the first, he accumulates food while grazing to form a cud. The second stomach contains digestive juices, while the third stomach is where the gum is being digested. In the walls of the first two stomachs are pockets for the accumulation of water. Muscles keep these pockets closed when they are full. As soon as the camel needs water, these muscles open the pocket, releasing as much water as necessary, and close again. So how long can a camel go without water? As you have already noticed, it does not do without water in the full sense of the word. There are cases when a person dying of thirst was sometimes forced to kill a camel in order to get precious water. If a camel walks slowly and his load is not very heavy, this water can last him for six or even ten days! Author: Likum A. Random interesting fact from the Great Encyclopedia: How is body temperature controlled? In a room or building, a thermostat regulates the temperature by controlling the amount of heat produced by the heaters. In the human brain there is a region called the thalamus, which acts as a kind of thermostat. It controls the amount of heat in the body and keeps it at around 37 degrees Celsius. The body burns food and oxygen to obtain energy, primarily heat. Since the body produces heat all the time, it must have some way to get rid of its excess. Otherwise, it will get hotter and hotter. The function of the thalamus-thermostat is to release some of the heat so that the body temperature remains constant. The air exhaled from the lungs takes some of the heat with it. Waste products, leaving the body, also take some heat with them. More of it comes out through the skin. It constantly releases heat from the body and that is why it always remains warm to the touch. The thalamus can cause the skin to give off more than normal heat, and less, if necessary. If the body gets too hot, more blood than usual rushes to the surface of the skin. As a result, more heat comes to the surface of the skin from the internal organs and, accordingly, more leaves the body into the air surrounding it. On the other hand, if the body cools down, the capillaries under the surface of the skin constrict - and the blood flow here decreases. And the less blood circulates at the surface of the skin, the less heat it gives off. If our body gets too hot, we start to sweat. Sweat is a brackish liquid produced by the sweat glands. From these glands to the pores on the skin are thin tubes through which sweat enters the surface of the skin. There it evaporates, accelerating the release of heat by the body. Moisture turns into gas and escapes into the air, taking with it the excess heat. This is why you feel colder when your skin is damp than when it is dry.
