Blood: Path of a Red Blood Cell

Despite slightly older animation, this fascinating video shows the path each red blood cell takes as it carries oxygen throughout the body. From the first pump of the heart pushing red blood cells to the lungs to pick up oxygen to the second pump of the heart pushing the cells out to the body, oxygen is carried and dispersed when the capillaries are oxygen-depleted. Informative and scientific, this video is sure to be a great resource in your biology classroom.
