Human physiology

Main article: Human body § Human physiology

The human skull at birth, with its fontanelles, presents many important anatomical and physiological features.

Human physiology seeks to understand the mechanisms that work to keep the human body alive and functioning,^[3] through scientific enquiry into the nature of mechanical, physical, and biochemical functions of humans, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems within systems. The endocrine and nervous systems play major roles in the reception and transmission of signals that integrate function in animals. Homeostasis is a major aspect with regard to such interactions within plants as well as animals. The biological basis of the study of physiology, integration refers to the overlap of many functions of the systems of the human body, as well as its accompanied form. It is achieved through communication that occurs in a variety of ways, both electrical and chemical.^{[citation needed]}

Much of the foundation of knowledge in human physiology was provided by animal experimentation. Physiology is the study of function and is closely related toanatomy which is the study of form and structure. Due to the frequent connection between form and function, physiology and anatomy are intrinsically linked and are studied in tandem as part of a medical curriculum.^{[citation needed]}
