Figure

Reflex for minimizing the decrease in body temperature that occurs on exposure to a reduced external environmental temperature. This figure provides the internal components for the reflex shown in Figure 7-1. The dashed arrow and the Q indicate the negative-feedback nature of the reflex, denoting that the reflex responses cause the decreased body temperature to return toward normal. Two flow-diagram conventions in addition to those described in Figure 7-1 are shown in this figure: (1) Blue 3-dimensional boxes always denote events that are occurring in anatomical structures (labelled in bold, underlined type at the upper right of the box); and (2) the phenomenon of negative feedback is denoted by a circled minus sign at the end of a dashed arrow.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
