My name is OJ. I go to stonehill international school. I want to talk about medical tecnology.
ritght now i will talk about the timeline of medical tecnology.
1. 2600: a man named Imhotep wrote texts about anicient egyptian. He talked about treament to of 200 different disesaes in Egypt. he must have been a very intelligent man.
2. 220 : A man named Zhang Zhongjing publishes the worlds oldest medical textbook. He made a great contribution to traditional chinese medicine. He had estabalished the medical principals of that time. this means Zhang must have been a very important man.
3. 180:
Galen studies the connection between
paralysis and severance of the
spinal cord. this is very important dicovery for the medical industry.
middle ages
1242 –
Ibn an-Nafis suggests that the right and left
ventricles of the
heart are separate and discovers the
pulmonary circulation (the cycle involving the
ventricles of the
heart and the
lungs) and
coronary circulation,
[10] for which he is considered the pioneer of
circulation theory[11] and one of the greatest
physiologists of the Middle Ages.
[12] He emphasized the rigours of verification by
measurement,
observation and
experiment, and was an early proponent of
experimental medicine, postmortem
autopsy, and human
dissection.
[13] He also discredited many other erroneous
Avicennian and
Galenic doctrines on the four humours, pulse bones, muscles, intestines, sensory organs, bilious canals, esophagus, stomach, and the anatomy of other parts of the
human body.
[14] Ibn al-Nafis also drew diagrams to illustrate different body parts in his new physiological system. this dicovery will help doctors cure heart diseases.
