The Human body
Man's Large.complex brain more than makes up for the inadequacy of his other senses.because of this,he can think logically,as well as having a sense of history, a conception of the future,and the ability to philosophize about his place in the universe.
Man has a good sense of smell,althoug it is not as powerfulas that of animals such as dogs.in the wild,smell is useful for identifying food,the presence of other creatures, and dangers such as forest fires.
Wild animals are used to listening for danger urban man,however,lives in a noisy environment,which can reduce the sensitivity of his ears,and his desire to listen carefully.
Humans have teeth both for cutting meat,and for grinding and chewing plants.the teeth are thus adapted for an omnivorous diet.
Taste buds on the tongue allow humans to perceive sour,sweet,salty,and bitter flavours.the brain interprets information from the foods smell to give aparticular taste.
By pumping oxygen-rich blood around the body,the heart keeps all the other organs working.whithout regular exercise,however,the heart becomes unfit,stopping the rest of the body from functioning properly.
The breating rate of humans depends on how much oxygen the brain thinks the body needs.the rate increases during exertion of fright,and at high altitudes,where the air contains a low amount of oxygen.
Humans are still designed to walk on four legs,and back trouble is often the price for standing up right on two.
As well as protecting internal organs,skin control body temperature through sweating.having lost most of its protective hair over the canturies,human skin now has to be shielded from sun,rain and cold.
Humans have thumbs and fingers that can work independently and grip objects.this allows for the making and use of complex tools,and ability that greatly contributes to mans adaptability.
Certain joints,such as the knees,are weak and prone to injury.in urban life,humans do not get enough exercise .this highlights these design weaknesses.
With all the weight of the body resting on the feet,injuries and other foot problems are common, especially in rough terrain.
~The Human Animal~
Man Is bardly a physical match for most other animals.in the wild he can become prey to other predators,unable to defend himself with talons,claws,teeth,or break,or to protect himsefl with a carapace or hide.he lacks the eyesight and sense of smell of other hunters,and also the speed to outrun game.he can not maintain body temperature in some environments without special clothes.man is, however, a natural survivor,forced through physical weakness to develop his dexterity and intelligence-the ultimate survival skills.
