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.

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.

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

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.

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

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

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.

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.

Learners play a game of Tic-Tac-Toe to test their knowledge of non-malignant qualitative and quantitative disorders of white blood cells.

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

Laboratory testing begins with a doctor's order and is followed by specimen collection. In this activity, learners review doctors’ lab orders and select the blood collection tubes required for each patient.
