The Will to Survive: Defense Mechanisms

The will to survive: the defense mechanism has emphasized the necessity of survival as human beings, especially from the time of contemporary medicine and the comforting techniques and livelihoods for people living in today's world. Over the centuries people have fought for the inhabitants of this planet and have continued to extend human life. Many of these surviving ideologies have disappeared from the culture of the world, especially in Western civilization, but many people have difficulty maintaining their lives everyday.

Stress is a classic fight and reaction of flight, which is the first, automatic, genetic wisdom we are involved in and when we face the threat of mountain lions and bears Survival instinct, defense mechanism. The nervous system releases chemical substances into the body, raises the heart rate, makes the breathing faster and shallower. My muscles get nervous and watch out. Then you can fight bears or escape to avoid danger. Chemicals are consumed in the process and we return to normal

Survival and breeding in the wild are the most common target of species. Various animal defense mechanisms help to achieve this goal. One of the defense mechanisms acquired by some animals is the ability to produce toxic venom. This poison can be used to help protect them, or it can be used to help capture food to fix their prey. There are many different marine animals with this special ability to produce toxic venom. Jellyfish has a complex stinging technique. Adopt puncture cell discharge method for puncture wound. Cannaria occurs in the sac of capsular cells. When the coating of this barbed wire is disturbed, stinging cells are released. This is caused by a large influx of water pressure. The hooked pouch has few hooks / thorns useful for attachment to prey. When this occurs, the toxin enters the prey and begins to function.

In their fight for survival, plants have evolved defense against herbivores. There are three main types of defense used by plants. The first defense mechanism is mechanical defense, including physical features such as thorns and needles. The second plant defense is a mast that involves producing more offspring than any predator can consume. An example is an oak or beach tree. These emit many cones that predators can not consume. The last type of defense is chemical defense, which consists of five subgroups. The first chemical reaction is a secondary metabolite. This type of defense prevents herbivores from using central metabolism for plant digestion. The second type of chemoprotection creates an unpleasant taste that prevents predators from eating plants. These plants usually contain terpenes and phenols. Some plants that use this mechanism are towata and mustard.
