Human Anatomy and Physiology / As Per PCI - ER 2020

The scientific study of the human body's structures is known as anatomy. Some of such structures are quite tiny, making the use of the microscope essential for their examination. It is simple to see, handle, measure, and weigh other, bigger structures. The Greek origin of the word for "anatomy" implies "to cut apart." Human anatomy was first studied by looking at people's scars and other external signs of injury. Later on, doctors were permitted to learn more by dissecting human corpses. Dissection is the process of separating parts of a body so that their individual properties and connections may be studied. Medical schools, anatomy classes, and pathology laboratories all make use of dissection today. However, several imaging methods have been created to allow for the observation of structures in live persons. Using these methods, doctors may see malignant tumours or broken bones inside a live patient. The focus of physiology is on function, whereas anatomy is more concerned with structure. Human physiology is the scientific study of a body's structures and their chemical and physical interactions to maintain life. The human body's natural propensity toward homeostasis is at the heart of most research in the field...
