What is the difference between anatomy

The study related to any body part of a living being is known as anatomy. The body of any living being on the earth has various parts. Some of the body parts can be viewed by naked eyes whereas some can be seen with the help of a microscope.

Study-related the body parts of human beings is called human anatomy. The idea of the importance of human anatomy pops in the mind when soldiers get injured. This interest helps in allowing physicians so that they can cut the human body and learn more about human anatomy.

Dead bodies of human beings are dissected in medical institutions as part of this subject so that students can gain information about various body parts.

Nowadays, there are various technologies that help in understanding the internal organs of the body. Some of these technologies are X Rays, ultrasound , etc. There are two ways to understand the structures of the body. Regional anatomy helps in gaining the knowledge related to a particular area of the body like the abdomen. Systematic anatomy helps in understand how different structures of different regions of the body function together.

Physiology is also known as the science of life. Physiology is involved in studying how circulatory, digestive, excretory, endocrine, immune and many other systems work in the body of an animal.

The physiology of a living organism can be studied under five broad areas: cell physiology, system physiology, evolutionary physiology, defense physiology, and exercise physiology. The study of cell physiology describes the functions and interactions of the cell, transport mechanisms, and signaling pathways of the cell.

System physiology mainly focuses on building computational and mathematical models of complex biological systems. Evolutionary physiology describes the adaptions of organs and organ systems over multiple generations.

Defense physiology describes how the body reacts to stressful conditions. Exercise physiology is another part of physiology describing the effect of physical exercises towards the normal functions of the body.

Figure Human Digestive System. Anatomy: Anatomy is a branch of science, which studies the structure of humans, animals, and plants; especially, revealed by dissection and separation of body parts. Physiology: Physiology is the branch of biology which studies the functions of living organisms and their parts.

Anatomy: Anatomy focuses on the size, shape, and the location of the body structures in living organisms. Physiology: Physiology focuses chemical, physical and electrical process in the body of organisms. Anatomy: The understanding of the anatomy of a living organism is obtained by dissection and separation of body parts of a living organism. Physiology: The understanding of the anatomy of the living organism is critical in studying the physiology of that particular living organism.

Anatomy and physiology are the two branches used to study the living organisms in both biology and medicine. Anatomy describes the structure of body parts in living organisms, either at gross anatomical level or microscopic level. This resistance stabilizes the body by regulating the internal environment, even as the external environment changes. A stable internal environment is needed for normal physiological function and survival of a living system.

Maintaining a stable internal environment requires constant monitoring, mostly by the brain and nervous system. The brain, more specifically the hypothalamus, receives information from the body and responds appropriately through the release of chemical messengers such as neurotransmitters, catecholamines, and hormones.

These chemical messengers signal individual organs to change their functions in order to maintain homeostasis for the whole body. For instance, if blood oxygen levels are too low, the brain signals the muscles controlling the lungs to breathe faster to increase oxygen intake.

The brain also signals the heart to beat faster so other organs and tissues receive the oxygen they need. When oxygen levels return to normal, the brain signals the lungs and heart to return to their normal rates of function, a process called feedback.

Traditionally, the academic discipline of physiology views the body as a collection of interacting systems, each with its own combination of functions and purposes. Each system contributes to the homeostasis of other systems and of the entire organism. No system works in isolation, and the well-being of the person depends upon the well-being of the interactions between body systems.

The traditional divisions by system are somewhat arbitrary. Many organs participate in more than one system such as the heart and kidney , and systems might be organized by function, by embryological origin, or by other categorizations. For instance, the neuroendocrine system is the complex interactions of the neurological and endocrinological systems.

Together, the neuroendocrine system regulates many physiological processes, including those that maintain homeostasis. Furthermore, many aspects of physiology are not easily categorized by traditional definitions of organ systems because they are composed of interactions between organs in multiple organ systems. The study of how physiology is altered in disease is pathophysiology. Pathophysiology focuses on how physiological processes fail to maintain normal function, resulting in the manifestation of disease symptoms.

Human anatomy deals with how all parts of the human body interact to form a functional whole. The study of anatomy is separate from the study of physiology, although the two are often taught together. 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.

While anatomy and physiology study different aspects of human biology, together they provide a more complete picture of what the human body is and how it works. The human heart and lungs : Anatomy and physiology are complimentary disciplines as the structure of body systems often influences system function.
