Being in the dark about how your body works isn\'t something that should work well with you..so the goal of physiology is to explain the physical-chemical factors responsible for the origin, progress and development of the human life. It explains the specific characteristics and mechanisms of the human body that make it a living being. It involves complex control systems, sensations and emotions. Physiology therefore makes the body work automatically. The fact that we are sensing, feeling and knowledgeable beings is part of this automatic sequence of life~isn\'t that amazing?
