What role do animals play in tourism and entertainment?
Giraffes can send blood to their heads through their long necks because their blood pressure is very high. According to measurements, the blood pressure of giraffes is twice that of normal people. Why can't such high blood pressure make giraffes die of cerebral hemorrhage? This is related to the giraffe's body structure. First of all, the muscles around giraffe's blood vessels are very developed, which can compress blood vessels and control blood flow. At the same time, the skin and fascia of giraffe's legs and whole body are very tight, which is beneficial to the upward return of blood in lower limbs. Inspired by this, scientists are training astronauts to set up a special instrument to exercise for several hours every day to prevent the muscles around the astronauts' blood vessels from degenerating. When the spacecraft was launched, scientists developed a flight suit-"anti-load suit" based on the principle that giraffes can control blood vessel pressure with tight skin. With the increase of spacecraft speed, the anti-load suit can be filled with a certain amount of gas, thus exerting a certain pressure on blood vessels and keeping the blood pressure of astronauts normal. At the same time, the lower part of the astronaut's abdomen is covered with a sealing device to exclude air, which can reduce the blood pressure of the astronaut's leg.
Animals can be regarded as an ornamental project in tourism, such as the zoo.
Well-trained animals can increase the fun of entertainment, such as circus is also a large-scale entertainment.
Animals in tourist attractions can not only watch, but also maintain ecological balance.
Animals in entertainment make people know more about animals, get closer to animals and promote the harmony between people and animals.
