Understanding Basic Blood Pressure Control - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: This video will help you understand how blood pressure is controlled in your body. Blood pressure is the amount of force caused by blood pressing against the walls of your arteries. It is tightly controlled to ensure sufficient blood reaches all parts of your body. Arteries are blood vessels that carry blood away from your heart to your tissues. This blood supplies your tissues with the oxygen and nutrients they need to function. In your heart, there are two lower chambers, called ventricles, which contract with each heartbeat. The right ventricle pushes oxygen poor blood to your lungs to pick up oxygen, and the left ventricle pushes oxygen rich blood through your arteries to your body. As blood flows through your arteries, four main factors affect the pressure on the artery walls. The first is the amount of blood your ventricles push out of your heart each minute, also known as cardiac output. Your blood pressure goes up as cardiac output increases. The second factor affecting your blood pressure is the total amount of blood in your body, or blood volume. Blood pressure also goes up as blood volume increases. The third factor that affects your blood pressure is resistance. Resistance is anything working against the blood flow through your arteries. Resistance is mainly affected by the width of your arteries. Your body is able to increase the width of your arteries to lower your blood pressure, or it can reduce the width to raise your blood pressure. The fourth factor that affects your blood pressure is viscosity. Viscosity is how thick your blood is. In your blood, more particles, such as proteins and fat, increase viscosity. If your blood is thicker, your blood pressure goes up as your heart works harder to push it through your arteries. If you have questions about high blood pressure or any medications you have been prescribed, speak with your doctor. It is important to take your medications as directed and report any side effects you have.

What attorneys say about MLA and The Doe Report:
"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 a medical illustration created by Medical Legal Art at the beginning of every case to tell the client's story, usually before I depose the defendant doctor. The work product and cost-efficiency are outstanding. It is a situation where, as a trial lawyer, I don't leave home without it."

Rockne Onstad
Attorney at Law
Austin, TX

"For modern audiences, it is absolutely essential to use medical demonstrative evidence to convey the severity and extent of physical injuries to a jury. Your company's high quality illustrations of our client's discectomy surgery, combined with strong expert testimony, allowed the jury to fully appreciate the significance of our client's injuries.

We are very pleased with a verdict exceeding $297,000.00, far in excess of the $20,000.00 initially offered by the defendant. The medical demonstrative evidence provided by Medical Legal Art was an asset we could not have afforded to have been without."

Todd J. Kenyon
