This Will be The most terrific post here in espiya.net.... ( i think... )

nakaka amaze lang naman talaga ang human body...

napakagaling talaga ng designer ng katawan natin, masyadong kumplikado, aba eh kung nagkamali siya eh tiyak na patay na tayo....

truly, GOD IS GREAT!!!!

Description: In Channel 4ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚Â¢s Anatomy for Beginners you can see a real and spontaneous demonstration of human anatomy. The beauty and intricacy of the human body is laid bare in a sophisticated modern version of a tradition that extends back to the middle ages and beyond.

Here, you can see highlights of the dissections and learn more about your body. Your anatomical guides will be Dr Gunther von Hagens who dissects the bodies and pathologist Professor John Lee who explains how they work in health and in disease.

1. Movement
The body was opened to reveal the muscles, tendons, ligaments and bones that interact to make up the mechanics of movement. Also revealed were the brain and spinal cord that drive and coordinate movement along with peripheral nerves that convey instructions from the central controllers to the muscles. In this demonstration, Dr von Hagens placed the body in an upright position using a head clamp and ropes to suspend it from an overhead frame. ItÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚Â¢s unusual to perform a dissection on a body in this position. For practical reasons, they are usually performed on bodies lying flat on a dissection table. However, the systems of movement can only be effectively revealed for a public demonstration when the body is in this vertical position. Medieval artists would have been familiar with cadavers that were suspended vertically so that they could be sketched. Oddly enough, few people today, including professional doctors and anatomists, will have witnessed an upright dissection. The body hadnÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚Â¢t been preserved with a fixative but had been stored frozen. This allowed for a demonstration of movement, which wouldnÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚Â¢t have been possible after fixation due to tissue stiffness.

2. Circulation
Two interrelated systems were revealed: the lungs or respiratory system, and the heart and blood vessels or circulatory system. Both systems are involved in oxygen metabolism. Oxygen enters the body via the lungs, and is there combined with blood. The arterial system of blood vessels carries oxygen to the tissues, where it provides the energy for life. Spent oxygen, in the form of carbon dioxide, is then carried back to the lungs via a system of veins and exhaled into the environment. This process continues silently every second of life. The heart and lungs are constantly on the go. Every part of the body needs to be supplied with oxygen and needs to have waste products such as carbon dioxide removed. If circulation stops, the consequences are immediately disastrous. The brain is most sensitive to lack of oxygen ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œ without it we lose consciousness within seconds and the brain is irreversibly damaged within a minute or two. The systems of circulation are best revealed with the body in the traditional prone position on a table. In this dissection, the body hadnÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚Â¢t been preserved with a fixative but had been stored frozen. This allowed for a demonstration of inflation and deflation of lungs and injection of the blood vessels, which wouldnÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚Â¢t have been possible after fixation due to tissue stiffness.

3. Digestion
This demonstration uncovered the organs that carry food through the body, from the mouth to the anus, taking in various different portions of the digestive tract (also know as the gut or intestine). It also revealed the organs that support the gut in digesting food, like the liver and pancreas, together with those that help remove waste products from the body fluids, like the kidneys. Dr von Hagens placed the body in an upright position, using a head clamp and ropes to suspend it from an overhead frame. It is unusual to perform a dissection on a body in this position, but the full length of the digestive system is more effectively shown using an upright body. This body was preserved with a chemical known as formalin, which was injected into the blood vessels. This sterilises the body and stiffens the tissues, allowing for demonstration of delicate structures such as those of the digestive system.

4. Reproduction
Dr von Hagens revealed the organs that carry a sperm from its origin in the testis, through many metres of convoluted tubing and into the female genital tract. The dissection, especially of the male genital tract, is challenging because many of the tubes are small and hidden within the bony walls of the pelvis. The dissection involved cutting through the bones of the pelvis in just the right place to keep the relevant organs in tact. Once in the female genital tract, the sperm must use its own energy to swim through the cervix and uterus, until it meets an egg (or ovum) in the fallopian tube near the ovary. Once fertilisation takes place, the sperm and ovum are replaced by a zygote, which has the potential to form a human foetus. The zygote moves to the uterus where it develops into a baby. Finally, the baby passes through the birth canal into the outside world eventually to begin the whole cycle again. This body was preserved with a chemical known as formalin, which was injected into the blood vessels. This sterilises the body and stiffens the tissues, allowing for demonstration of delicate structures such as the reproductive organs.

nice post tol.. medicine student will surely like this post. pure theory is inadequate without visual and hands on in the field of medicine..
