Anatomy and Physiology Quiz

Anatomy and Physiology: The Study of the Human Body

• Anatomy is the study of the structure and shape of the body and its parts, while physiology focuses on how the body and its parts work and function.
• Gross anatomy deals with large, easily observable structures, while microscopic anatomy examines structures that are too small to be seen with the naked eye, such as cells and tissues.
• The term "anatomy" is derived from the Greek words "ana" (apart) and "tomy" (cut), reflecting the practice of dissecting and examining the body's structures.
• Physiology comes from the Greek words "physio" (nature) and "ology" (study of), emphasizing the study of the natural functions of the body.
• The structure of an organ determines the functions that can occur within it.
• Pathophysiology is a field of study that focuses on the changes in bodily functions that occur due to disease.
• The levels of structural organization in the body start with atoms, which are the smallest units of matter.
• Atoms combine to form molecules, which are the building blocks of cells.
• Cells are the smallest unit of living things and vary in size, shape, and role in the body.
• Simple creatures consist of only one cell, while complex organisms have cells that organize into tissues.
• Tissues are groups of similar cells that have a common function.
• There are four basic tissue types: epithelial, connective, muscle, and nervous.
