Learners follow the path of a carbohydrate food from consumption through digestion to absorption into the bloodstream. In a matching exercise, students identify the main type of carbohydrate found in four different foods.

In this animated activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.

In this animated and interactive object, learners identify the valves and chambers of the heart.

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

In this animated and interactive object, learners conduct an experiment online to illustrate how a greater number of particles in a "vessel" increases osmotic pressure.

In this animated and interactive object, learners identify the valves and chambers of the heart.

In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.

Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
