Changes in physiology can impact the mental functions of individuals. Examples of this would be the effects of certain medications or toxic levels of substances. [9] Change in behavior as a result of these substances is often used to assess the health of individuals. [10] [11]
A prominent example of metaplasia involves the changes associated with the respiratory tract in response to inhalation of irritants, such as smog or smoke. The bronchial cells convert from mucus-secreting, ciliated, columnar epithelium to non-ciliated, squamous epithelium incapable of secreting mucus. These transformed cells may become ...
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testicles in a boy.

For example, with people in their 40s, Snyder and his team discovered significant changes in the number of molecules related to alcohol, caffeine, and lipid metabolism, as well as cardiovascular ...
This change can be detected by an organism or organ using sensitivity, and leads to a physiological reaction. [2] Sensory receptors can receive stimuli from outside the body, as in touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors.
The following outline is provided as an overview of and topical guide to physiology: . Physiology – scientific study of the normal function in living systems. [1] A branch of biology, its focus is in how organisms, organ systems, organs, cells, and biomolecules carry out the chemical or physical functions that exist in a living system.
Also, humans had physiological mechanisms that reduced the rate of metabolism and that modified the sensitivity of sweat glands to provide an adequate amount for cooldown without the individual becoming dehydrated. [17] [20] There are two types of heat the body is adapted to, humid heat and dry heat, but the body adapts to both in similar ways.
