Blood Vessels and their Function [Silent] (J. Sarnoff, Bray Productions, 1925)
The functions of the blood vessels are discussed. A post-mortem specimen of the heart, great vessels, kidneys, uterus, ureters, and adnexa is shown with the heart pulsating. Diagrams with moving arrows illustrate blood flow. Blood flow through the arteries and veins is shown cinemicrographically. Animated graphics illustrate oxygen, carbon dioxide, and cell waste movement. A physician is shown feeling the radial pulse. A male model, nude to the waist and with a pulsating heart photographically superimposed on his chest, has his chest listened to by a physician with a stethoscope. A hand is shown pumping up a sphygmomenometer, the column of mercury rising and falling. A post-mortem heart is shown and the aorta pointed out. Good habits and hygiene are advocated so that the blood vessels may keep themselves in good repair.
Produced by Dr. Jacob Sarnoff and Bray Productions.
