Examples of physiological responses are changes in heart rate, a higher respiration rate, sweating, changes in body temperature and changes in blood pressure. All of these occur in response to pain. The human body has an integrated defense response, which includes flight or fight.
The study of physiology and physiological changes dates back to around 420 B.C. Physiological changes are part of life and may be caused by internal and external forces. For example, pregnancy causes profound physiological changes in both people and animals, and external forces such as pollution also have a physiological effect on living organisms.
However, physiological responses can also be elicited by complex and idiosyncratic stimuli mediated by the forebrain. For example, an anticipated tryst with a lover, a suspenseful episode in a novel or film, stirring patriotic or religious music, or dishonest accusations can all lead to autonomic activation and strongly
Physical changes involve states of matter and energy. No new substance is created during a physical change, although the matter takes a different form.The size, shape, and color of matter may change. Physical changes occur when substances are mixed but don't chemically react.
Physiological changes occur with aging in all organ systems. The cardiac output decreases, blood pressure increases and arteriosclerosis develops. The lungs show impaired gas exchange, a decrease in vital capacity and slower expiratory flow rates. The creatinine clearance decreases with age although the serum creatinine level remains relatively ...
physiological definition: The definition of physiological is the normal functions of a living thing. (adjective) An example of physiological is a person shedding skin....
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Often, physical changes can be undone, if energy is input.
Coronary heart disease, stoke, many types of cancer, osteoporosis, Alzheimer's disease, Parkinson's disease, and osteoarthritis are examples of such diseases commonly found in elderly people. Indeed, age-associated disease underlies much of the physiological deterioration of old age.
Physiological definition is - of or relating to physiology. How to use physiological in a sentence.
A physical change is any change in matter that involves the substance going from one physical state to another. The reference to a physical state involves solids, liquids, and gases. When a substance undergoes a physical change it does not lose its original properties when changing from one phase to another. The types of physical changes can vary.
