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

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.

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

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

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

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 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.

Students will learn how to document bloodstains using roadmapping equipment materials

This learning object describes the equipment and supplies needed to document bloodstain patterns.

In this interactive object, learners review case studies and identify complex arterial blood gases.

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.

Learners read an introduction to arterial blood gasses and then identify uncompensated ABGs.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.

In this learning object, students will learn about the attachment

process of specific sugars to red cell membranes and how the sugars

determine ABO antigenic activity.

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