Metabolic Rate Calculator
Baed on findings of measurements of metabolism on huge samples of healthy population, empirical formulas were suggested that enable to calculate expected basal metabolic rate from age, sex and body size. Use the calculator to find your expected basal metabolism.

Autonomic Nervous system - overview
Animated scheme of the Autonomic control of body functions. Turn information on or off for step-by-step study or self - testing. The autonomic nervous system (ANS or visceral nervous system or involuntary nervous system) is the part of the peripheral nervous system that acts as a control system functioning largely below the level of consciousness, and controls visceral functions. The ANS affects heart rate, digestion, respiratory rate, salivation, perspiration, diameter of the pupils, micturition (urination), and sexual arousal. Whereas most of its actions are involuntary, some, such as breathing, work in tandem with the conscious mind.
Cardiac output measurement - Thermodilution
Interactive Flash animation demonstrating the principles of thermodilution measurement of cardiac output. (flash animation). Measuring cardiac output is of paramount importance in the management of critically ill patients in the intensive care unit and of 'high risk' surgical patients in the operating room. Alternatives to thermodilution are now available and are gaining acceptance among practitioners who have been trained almost exclusively in the use of the pulmonary artery catheter.
Oxygen consumption estimation (animation)
One-page interective animation (Flash) explaining how to estimate O2 consumption from Minute Ventilation (measured) and O2 concentration in expired air (measured). The Physiology lab procedure "Metabolic rate measurement" is based on this principle. Measurement of the rate of oxygen consumption provides a simple, versatile and powerful tool for estimating the rate of heat release in fire experiments and fire tests. The method is based on the generalization that the heats of combustion per unit of oxygen consumed are approximately the same for most fuels commonly encountered in fires.
Introduction to Biological Psychiatry
Biological psychiatry occupies itself by mental disorders from biological, chemical and physical point of view. It is postulated that changes in brain signal transmission are essential in development of mental disorders. The purpose of this teaching material is to describe cellular and molecular properties of neurons, mechanisms of psychotropic drugs action and biological basis of mental disorders. Familiarity with biochemistry and physiology is supposed.
