What is the study of the functions and activities performed by the body's structures?

The study of the functions and activities performed by the body's structures is known as physiology. This field focuses on how different systems and organs in the body operate, interact, and contribute to the overall functioning of the organism. For example, physiological studies might explore how the respiratory system facilitates gas exchange or how muscles contract during movement.

Understanding physiology is essential for nail technicians since the health and function of nail bed structures can be influenced by bodily systems. Knowledge of physiology helps technicians make informed decisions related to nail care and recognize potential health issues that may manifest through nail appearance or health.

Anatomy, while related, specifically deals with the structural organization and physical relationships of various body parts rather than their functions. Histology focuses more on the microscopic structure of tissues, and cytology is concerned with the cellular structure and function. Each of these fields contributes to a comprehensive understanding of the body, but it is physiology that directly addresses how these structures perform their roles in maintaining health and supporting life.
