Cell Physiology: The study of how cells work and function. It focuses on the atoms and molecules that are essential for life, exploring both the chemical activities inside cells and how cells interact with each other.
Organ Physiology: This examines how specific organs function. For example, Cardiac Physiology looks at how the heart operates.
Systemic Physiology: This covers the functions of entire organ systems. Examples include Cardiovascular Physiology (how the heart and blood vessels function), Respiratory Physiology (how we breathe), and Reproductive Physiology (how reproduction occurs).
Pathological Physiology: This studies how diseases affect the functions of organs and system functions.A solid grasp of both normal physiology and pathological physiology is vital for modern medicine.
