This screencast will help the student identify normal blood cells and their functions. This will include the identification of red blood cells, five types of white blood cells, and platelets.

Learners examine microscope images of blood agar and the various types of hemolysis that can be detected. A quiz completes the activity.

In this interactive object, learners review descriptions of various blood collection tube additives. They then test their knowledge by matching the different tubes to their corresponding additives.

In this animated and interactive object, learners examine ABO blood antigens and Rh antigens and their compatibility.

This learning object has been created to educate workers about the occupational risks of being exposed to bloodborne pathogens as described in the U.S. Occupational Safety and Health Administration (OSHA) 29 CFR 1910.1030- Bloodborne Pathogen Standard.

In this interactive object, learners read about the occupations that are most at risk for bloodborne pathogen exposure. They also read about the most common pathogens and how they are transmitted. This learning object is based on information from the U.S. Occupational Safety and Health Administration.

Learners examine OSHA's guidelines of what to include in a bloodborne pathogen exposure control plan for persons who work in general industry, health care, emergency medical services, law enforcement, education, recreation industries, or other occupations in which there is a potential for exposure to blood, blood products, bodily fluids, or human tissues.

This screencast shows how blood droplets are held together by a strong cohesive molecular force that produces surface tension in each drop and on the external force. Surface tension pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.

Students read an explanation of the values used for arterial blood gas analysis.

In this animated and interactive object, learners examine the red blood cell's life cycle and function. A brief exercise completes the activity.

In this learning object, you will learn about four blood osmolality and volume regulators, their sites of production, their sites of action, and the results of those actions.

Learners complete a crossword puzzle with terms that relate to common diseases and disorders of the blood. Immediate feedback is provided. Learners have the option to send an e-mail to their instructors notifying them that the learning object has been completed.

This activity will summarize the bloodstain evidence documentation process.

In this animated and interactive object, learners examine the structure and functions of granulocytes and agranulocytes. Two exercises complete the activity.

Learners read a scenario about a blood-borne pathogen incident in the workplace and decide the best action to take.

Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.

Learners examine the different stages of maturation for red blood cells, white blood cells, and platelets. A quiz completes the activity.

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

Learners examine a CBC and study the functions of blood cells, the normal range for each item on the CBC, and possible reasons for increases or decreases from the normal range.

Explore how to collect a fresh or dry blood specimen and prepare it for the crime lab.
