Respiration and Circulation: Gas Exchange, Molecular Transport DVD

A great, cost-effective supplement to your school's biology curriculum. This DVD comes complete with printable PDFs of study guides, worksheets, and an annotated script explaining interesting shots along with the location and circumstances involved in capturing them. It looks at the flow of air through the conducting portions of the respiratory system to the alveoli before examining the role of hemoglobin in gas exchange and oxygen (as well as carbon dioxide) transport in the blood; the operation of the respiratory control center; and the mechanics of breathing.

The program then investigates the composition of blood and how it flows through the heart, arteries, capillaries, and veins before looking at the role of the lymphatic system in fighting infection, transporting fats, and returning interstitial fluid to the blood.
