In this animated and interactive object, learners identify the valves and chambers of the heart.

In this animated activity, learners practice listening and counting the apical pulse of adults, children, and infants.

In this screencast, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.

In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.

In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.

In this animated activity, learners examine the symptoms of four cardiac conditions: coronary artery disease, myocardial infarction, congestive heart failure, and valvular disease.

In this screencast, learners identify the parts of the cardiovascular system and examine blood flow.

The user completes a fill-in-the-blank exercise to review the anatomy of the heart.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

In this video learners view the valves and chambers of the heart.

In this animated activity, users examine the causes of malfunctions in a hydraulic pressure-reducing valve and the problems that result. A short quiz completes the learning object.

In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.

The operation of a hydraulic brake valve, including the internal components, is presented using animations.

In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.

Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.

In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.

Learners use animated needle valves and check valves to change the speed of a pneumatic cylinder as it extends and retracts. A brief quiz completes the learning object.

Learners view an animation of a sequence valve in operation and examine the valve’s internal structure.

In this animated object, learners examine the operation of a hydraulic relief valve and its internal components. A brief quiz completes the activity.

Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
