Film documentary on the life and times of Charles Drew who did research 'in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge in developing large-scale blood banks early in World War II, saving thousands of allied lives'
Charles Drew - Inventor of the Blood Bank
Commentary, still images, and narration about Charles Drew. Commentary is provided by Dr. Lester Rodney of Morehouse Colllege. Drew did research 'in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge in developing large-scale blood banks early in World War II, saving thousands of allied lives' (Wikipedia, 2009).
Overview of Charles R. Drew's Life
Commentary, still images, and narration about Charles Drew. Drew did research 'in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge in developing large-scale blood banks early in World War II, saving thousands of allied lives' (Wikipedia, 2009).
The Nephron: Blood Filtration and Urine Production
Professor George Wolfe discusses the nephron, blood filtration and urine production in this video from Thinkwell's online Biology series. The video uses lecture format along with notes and illustrations on a board. Run time 12:33.
This professional video gives close-up footage and describes the characteristics of bed bugs. Video shows how bed bugs suck your blood. The video could be used with a lesson about symbiosis and parasites. 2:10 min.
Simple animation shows how a cancerous tumor grows and spreads through the body. Cancer occurs when cells grow out of control. The cells travel through the blood stream. 46 sec.
Blood Vessels Help Tumors Grow
This video segment, adapted from NOVA, features cancer researcher Dr. Judah Folkman and describes his approach to proving a new idea he had about how tumors grow inside the body. His idea focuses on angiogenesis, the formation of new blood vessels. Dr. Folkman designed experiments to test his central hypothesis and thus prove the support mechanism behind tumors. Closed captioning included. Run time 05:07.
Breakdown of Blood Retinal Barrier In Diabetic Retinopathy
Description of how the retinal pigmented epithelial cells maintain the barrier between blood and the retinal tissue. Simple animation with text and computer generated narration. Grades 9-12. 1:13 min.
Heart Disease - Illumistream Health
Professional video explains what heart disease is and how the heart works. There are multiple conditions that affect how our heart works. The heart is a pump that pumps blood in and out of the heart. A doctor explains what is happening using animations and pictures. Atherosclerosis, angina, and aneurisms are discussed. 2:56 min.
Understanding High Blood Pressure
A quarter of Americans have high blood pressure, or hypertension. In this video, a doctor uses diagrams to explain what high blood pressure means, why it is of concern to your health, and how it is diagnosed. 3:09 min.
A Search for Viruses in the Jungle
Virus hunter Nathan Wolfe is outwitting the next pandemic by staying two steps ahead: discovering deadly new viruses where they first emerge -- passing from animals to humans among poor subsistence hunters in Africa -- before they claim millions of lives. Armed with blood samples, high-tech tools and a small army of fieldworkers, Nathan Wolfe hopes to re-invent pandemic control -- and reveal hidden secrets of the planet's dominant lifeform: the virus. Run time 12:16.
Immune Cells in Action
In this video segment from The Secret of Life, you'll look through a microscope at a virus attacking a cell. Viruses continue to replicate until they break apart the host cell and start spreading throughout the body, destroying healthy cells along the way. You'll learn how the immune system overpowers a virus with white blood cells and creates the antibodies that kill the same types of viruses quickly if they return. Closed captioning included. Run time 01:40.
The Urinary System
The urinary system is concerned with the formation and elimination of urine. In an adult, more than 2,500 pints of blood passes through the kidneys each day. Blood enters via the renal arteries and is filtered to remove most of the waste products of metabolism. Seven pints of filtrate are produced every hour. Purified blood returns to the body circulation via the renal veins. The filtering process is carried out by more than two million tiny kidney units, or nephrons, which produce a highly conc
The Kidney and Nephron
This is an overview of how the nephrons in the kidney filter blood and re-absorb water and other molecules. Mr. Khan uses computer software (with different colors for clarification and emphasis) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
Anatomy of a Kidney
There is a very brief video with still images of the kidney. This is a quote from the video:
"This cross section of a kidney, almost three times life-size, shows its blood supply and one of the filter tubules, a nephron, highly magnified. The nephron is a highly specialized coiled tubule measuring up to one inch in length. There are more than one million nephrons in each kidney. They function as the kidney's filter units. The kidneys filter unwanted materials from the blood and regulate th
'The 'kidneys are a bean shaped, fist size organ whose task is to filter blood and remove the waste.' This is a quote from the video. The information is related in a 'dry' way but the content is usable. The instructor appears to be using slideshow.
Learn How the Kidneys Work
How do our kidneys filter our blood stream? This video deomonstrates and explains how our kidneys work by making a model using a water bottle, fish tank tubing, funnel, coffee filters, food coloring and water. Run time 03:52.
Hepatitis C Infection - 3D Medical Animation
This brief video is computer animation concerning the Hepatitis C virus which primarily infects the liver and is blood-borne. the video also tells what the symptoms are and how the disease may last for years and get progressively worse. Suitable for high school students.
Why Do Humans Have Adrenaline?
Adrenaline is a hormone and neurotransmitter that helps more
oxygenated blood move to the muscles. Discover why adrenaline is
identified with the "fight or flight response" with information from a
Formation of a Pulmonary Embolism
3-D animation of a blood clot forming in a lower leg vein, creating a deep vein thrombosis. When the thrombosis breaks free of the valve, it is called an embolus and travels toward the heart and lungs. The animation is set to music. Grades 7-12. 57 sec.
