It comes from the Greek word “ana” which means “to cut apart” and “tomia” which means “to cut.” Physiology: It is the scientific study of the chemistry and physics of the structures of the body. Also, the ways in which they work together to support the functions of life. The study of physiology centers on the body’s tendency towards Homeostasis. 2. Describe macroscopic andmicroscopic anatomy. Macroscopic (Gross) Anatomy: Is the study of larger structures in the body, those visible without magnification. Microscopic Anatomy: Is the study of structuresthat can be observed only with the use of a microscope or other magnification device. This also includes Cytology, the study of cells and Histology, the study of tissues. 3. Explain the relationship between structure and function. Structure: Anatomy is about structure Function: Physiology is about function. The study of anatomy and physiology makes more sense, if you continually relate the form of the structures you are studying to their function. 4. Describe various types of cells in the human body and explain the basic principles of the cell theory. Cell Theory: All biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. This is a unifying principle of biology. Scientists group cellsinto mostly two categories. These categories are prokaryotic cells and eukaryotic cells.
