Facts about human anatomy and physiology include the tendency of the human body to work to ward off overheating, as well the reality of the damaging effects of excessive volume on human hearing. Also noteworthy is the body's vast number of cells.Continue Reading
An large amount of small cells goes into the makeup of the human body. These cells are so small that some scientists estimate that 10,000 human cells could fit onto the head of a pin. Dead skin cells consist of keratin, which is the same substance that comprises human hair and fingernails. This substance is also found in certain structures in the animal kingdom, such as in claws, beaks, fur, hoofs and wool.
Among the physiological characteristics of the human body is its tendency to fight off overheating, especially during the hot months of the year. The process of heat acclimatization involves helping the body to prepare for heat increases by increasing blood volume and sweat, effectively arming the body with a quality cooling system. In contrast to these defensive measures, the body also has delicate and sensitive parts that are susceptible to damage. The human ear's cochlea is a sensitive instrument that loud sound can quickly harm.Learn more about Human Anatomy
