Anatomy & Physiology

Through engaging, state-of-the-art laboratory simulations, you’ll discover the fascinating world of the human body—from cellular structure and organ systems to basic chemistry and challenging physiology concepts.

Featured Simulations for Anatomy & Physiology

Skeletal Muscle: Electrical Stimulation , Link will open in a new tab

In this simulation, you will electrically stimulate a frog’s leg muscle using an electrode.

Cardiovascular Physiology: Blood Pressure , Link will open in a new tab

In this simulation, you will measure blood pressure, determine the effect of body position on blood pressure, and determine the effect of exercise on blood pressure.

Neuron Physiology , Link will open in a new tab

In this activity you will identify major structures of a typical multipolar neuron, view the factors involved in maintaining the resting membrane potential, and step through the major physiological events of the receptive, initial, conductive, and transmissive segments of a neuron.
