In this learning activity you'll review the structure and function of the different tissues of the human body.

Learners review the differences within the right and left parietal lobes. They answer questions based on a case study and describe a client in a second case study.

In this interactive object, learners read the definitions of prefixes and suffixes that relate to the digestive system. In a drag and drop exercise, the learners combine word components to form medical terms.

In this animated object, learners examine water molecules moving through a semipermeable membrane.

In this animated object, learners view hydrogen and hydroxide ions in a solution. A brief quiz on the basic principles of the term pH completes the activity.

This learning object shows how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.

Students read about how acid/base balance affects a person's health. This activity includes animation.

In this interactive object, the learner matches various disorders to the acid-base disturbances they cause.

Through the use of symbols and words, the learner reviews the etiologies, symptoms, and treatment of respiratory and metabolic acid-base disturbances.
