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 interactive object, learners identify the risk factors and the precautions to follow when treating a patient with a cardiac condition. They also design a treatment plan for that patient.

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

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

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

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 categorize cardiac risk factors and match the signs and symptoms of cardiac distress with the correct terms.

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

In this animated and interactive object, learners examine how blood flows through the heart and lungs. A brief quiz completes the activity.

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

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.

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

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

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.

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 activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.
