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

In this interactive object, learners sort veterinary cardiovascular system drugs into categories.

In this highly interactive and animated object, learners examine the VAT-40 battery starting and charging system tester and study how the tester is used to diagnose vehicle starting system problems. This object has audio.

Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.

In this animated object, learners examine the operation of a feed-forward control system and its advantages over a closed-loop system. A brief quiz completes the activity.

In this animated object, learners examine the operation of a closed-loop system that maintains the speed of a conveyer belt as heavy boxes are placed or removed.

In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.

Learners study an animated block diagram that describes the function of each element in a closed-loop system used in industrial automation.

In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.

Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.

Learners read a description of the wiring configuration of a residential Edison Wire System, which consists of a transformer secondary circuit. The circuit supplies two 115-volt sources and one 230-volt source.

This objects reviews the Five "S" manufacturing system and helps learners to remember the process.

Learners examine the function and wiring of the sympathetic nervous system.

Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.

Learners examine the factors that contribute to the delays in the response time throughout a closed-loop system.

Learners study two diagrams of the lymphatic system and then test their knowledge in drag-and-drop exercises.

In this screencast, learners review the parts of the gastrointestinal system and then check their knowledge in a matching exercise.

In this interactive and animated object, learners examine the SUN VAT-40 battery starting and charging system tester. This learning object demonstrates the use of the tester in diagnosing conventional 12-volt automotive charging systems. It contains audio.

In this interactive object, learners read the definitions of prefixes and suffixes that relate to the digestive system. They then use this knowledge to combine word components to form medical terms.

In this interactive object, learners sort veterinary nervous system drugs into categories.
