“Anatomy & Physiology” are two closely related fields of biology that study the structure and function of living organisms, particularly humans.
Anatomy:
- Anatomy is the branch of biology that focuses on the structure of organisms and their parts. It involves studying the physical organization of the body, including organs, tissues, and cells. Anatomy is often divided into two main areas:
- Gross Anatomy: The study of large body structures that are visible to the naked eye, such as the heart, lungs, bones, and muscles.
- Microscopic Anatomy (Histology): The study of structures that require a microscope to be seen, such as tissues and cells.
Physiology:
- Physiology is the branch of biology that focuses on the function of the body’s systems and organs. It examines how the body’s structures work individually and together to sustain life. Physiology is often divided into several subfields, including:
- Cell Physiology: The study of how cells function and interact.
- Systemic Physiology: The study of the function of specific organ systems, such as the cardiovascular system, respiratory system, and nervous system.
- Pathophysiology: The study of how normal physiological processes are altered by disease.
