Every physiological phenomenon (function) ultimately depends on the behavior of cells and their membranes. Cell Theory. All cells arise from other cells and thus, have the same DNA as their parent cell. All cells making up the organism have the same DNA.
Physiology is the science of life. It is the branch of biology that aims to understand the mechanisms of living things, from the basis of cell function at the ionic and molecular level to the integrated behaviour of the whole body and the influence of the external environment.
A physiologist is a specialized scientist who studies the normal functions and processes of living organisms, particularly the complex mechanisms within the human body.
While anatomy studies the structure of the parts of an organism, physiology is concerned with the way those parts function together. For example, an anatomist may study the types of tissues found in different parts of the heart, while a physiologist may study how the heart regulates blood flow to supply oxygen to other organs in the body.
Physiology is the study of how the human body works both when you’re healthy and when you’re not. When you’re sick or injured, normal physiology is disrupted. Physiologists often work as part of a team with medical care providers, pharmaceutical companies and other related professionals.
definition The precise meaning of a word or phrase. The meaning may depend on context: see e.g. 'control'. Scientific and physiological meanings often differ from those in an ordinary dictionary. Where there is ambiguity, the context should make the meaning clear.
Use appropriate anatomical terminology to identify key body structures, body regions, and directions in the body. Demonstrate the anatomical position. Describe the human body using directional and regional terms. Identify three planes most commonly used in the study of anatomy. Distinguish between major body cavities.
