02 Transport and Gas Exchange - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: The respiratory system regulates oxygen and carbon dioxide levels within the blood. Respiration includes ventilation, gas exchange between the air, blood, and tissues within the body, and the use of oxygen for metabolism. Inhalation allows oxygen to enter the body, pulling air into the nose and mouth, lungs, and into the air sacs called alveoli, where gas exchange takes place. Alveoli move freely when air is inhaled and exhaled. Capillaries are small blood vessels that line the walls of the alveoli. During gas exchange, oxygen enters and carbon dioxide exits the bloodstream via the alveolar-capillary membrane. Once oxygen molecules move from the alveoli into the capillaries, they dissolve into the plasma and enter the red blood cell or erythrocyte. Erythrocytes contain millions of soluble proteins called hemoglobin. Hemoglobin contains four subunits each capable of binding one molecule of oxygen. Once one molecule of oxygen binds to one of the subunits, the other sites bind oxygen more readily. Dissolved and bound oxygen flows through the arterial bloodstream to capillaries within tissues. Upon arrival, carbon dioxide loading of the erythrocyte promotes oxygen unloading. Oxygen metabolism within cells produces carbon dioxide gas as a metabolic waste. Carbon dioxide exits the cells and tissues and is converted into bicarbonate within the erythrocytes. Converting carbon dioxide to bicarbonate releases hydrogen ions that decrease oxygen affinity for hemoglobin, freeing the oxygen to be delivered to tissue cells. After delivering oxygen to the tissues, the carbon dioxide-rich blood returns to the lungs through the venous circulation and then to the pulmonary artery. Inside each erythrocyte, the bicarbonate conversion is reversed, recreating carbon dioxide, which diffuses across the erythrocyte into the alveoli and lungs and is excreted out of the body. ♪ [music] ♪

What attorneys say about MLA and The Doe Report:
"There is nothing like a great graphic depicting the real nature and extent of a victim's injuries to get full value for your client. I use Medical Legal Art for mediations as well as trial."

Geoff Wells
Greene, Broillet, Panish & Wheeler
Santa Monica, CA

"Medical illustrations are essential during trial for any medical malpractice case. The people at MLA have the uncanny ability of creating medical illustrations that simplify the most complex of medical concepts and human anatomy to a lay audience. The exhibits of MLA allow experts to easily describe complex concepts and human anatomy in a manner that could not be done otherwise.

In addition, their custom illustrations show in great detail the extent of injuries suffered and the devastating effects they have had on the client's anatomy. These custom illustration can show, side by side, the body before and after a catastrophic injury. The effect of this juxtaposition is unmatched by any testimony that can be adduced at the time of trial.

Even jurors after trial have commented on the ease with which they grasp medical concepts and anatomy once the MLA exhibits were introduced and used by my experts. Even judges who have "seen it all" are thoroughly impressed by the detail and sophistication of the illustrations.

I would not want to try a case without them."

"[I] have come to rely upon the Doe Report and your great staff of illustrators for all my medical malpractice cases. … Please know that I enthusiastically recommend you to all my colleagues.

Frank Rothermel
Bernhardt & Rothermel
"For us, the defining feature of effective demonstrative evidence is whether, by itself, the piece will tell the story of the case. Medical legal Art provides our firm with illustrations and animations that are clear and persuasive. Their exhibits tell the story in a way that allows the jury to understand a very complex subject, very quickly."
