Human Anatomy is basically the scientific study of human body structures. It is quite useful in terms of physiology, which is apparently the study of how and why certain structures work. It deals with human parts, including molecules, cells, tissues, organs, systems and their way of interacting. Human Anatomy also deals with outward characteristics, such as shape, structure, pattern, color, and composition. Physiology and biochemistry on the whole , Human Anatomy is often considered to be a basic medical science. The two vital divisions of human anatomy are: gross anatomy and microscopic anatomy. Here, gross anatomy refers to the study of human organs which can be seen without magnification. Wherein microscopic anatomy refers to the study of small anatomic parts that can only be seen with the help of a microscope.
