Hint: Anatomy and physiology are two of the most essential terms and areas of study in the life sciences related to the structure and functioning of the human body.
Complete answer: Anatomy refers to the internal and external structures of the body and their physical relationships, whereas physiology refers to the study of the functions of those structures.
Human anatomy is the study of the structures of the human body. An understanding of anatomy is key to the practice of medicine and other areas of health. It can be done by direct dissection. Gross anatomy refers to dissection and observation of body parts for structure analysis. Microscopic anatomy refers to analysis of living cells at microscopic level.
Physiology describes the vital function of living organisms and the function of their organs and organ systems. It is an aspect of science which deals with the function and malfunction of parts of the human body. It originates with the understanding of unicellular functions and correlates with the complex functioning of various organ systems.
Anatomy and physiology are always related. Both structure and function are vital for complete understanding.They co-exist and are symbiotically connected to each other.In the field of medicine so these two subjects are taught in combination in great detail. A good understanding of both subjects are prerequisite for human health and diseases.
Note: The anatomical position is the focal idea driving all depictions of area inside the body. It is like the position of the acclaimed Vitruvian Man. Here is an overall summary: i) An individual standing upright, facing forward. ii) Arms straight and hands held by the hips, palms facing ahead. iii) Feet equal and toes pointing forward.
