Human physiology studies how our cells, muscles and organs work together, how they interact. Physiology, sometimes referred to as the "science of life", looks at living mechanisms, from the molecular basis of cell function to the whole integrated behavior of the entire body.
The word "physiology" comes from the Ancient Greek physis, which means "nature, origin", and logia, which means "study of".





Human physiology is the science of the mechanical, physical, bioelectrical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. Physiology focuses principally at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge.

Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.

Human evolution is about the origin of human beings. All humans belong to the same species, which has spread from its birthplace in Africa to almost all parts of the world. Its origin in Africa is proved by the fossils which have been found there. The term 'human' in scientific means the genus Homo. ( homosapiens )

Homo sapiens is the binomial nomenclature (also known as the scientific name) for the human species. Homo is the human genus .
