"Evaluate the importance of various technologies, including Canadian contributions, to our understanding of internal body systems (digestive, circulatory or respiratory)"

Various technologies benefit humans of our understanding of the internal body systems such as the digestive, circulatory, and respiratory system. It gives us an image of what our body looks like and what can be done to improve the health of humans. 

The endoscope one of the many tools used to view the internal body system. It is a medical device of a long, thin tube that has a light and camera at the end. Images from the camera are shown on a screen to examine the internal surfaces of organs and tissues. It can be used to diagnose any illnesses such as stomach ulcers, chronic diarrhea, urinary tract infections, etc. There are even specialized endoscopes with different names for different purposes. Examples are bronchoscopes that examine the air passages of lungs, arthroscopes that examine the joints and colonoscopies that examine the colon. The endoscopes give humans a view of the internal system as well as a useful tool to diagnose some illnesses. 
Magnetic resonance imaging or MRI is a medical imaging technique used to provide a detailed imaging of the internal system. It can create 2D images and even 3D models. It can be used to diagnose many types of injuries as well as the details of body tissues. MRI systems can also provide an image of flowing blood of the circulatory system. The MRI gives us a huge advantage in viewing the body system and provides detailed imaging for a better understanding.

An external pacemaker was invented by a Canadian engineer John Hopps in 1950. This device used vacuum technology temporary external pacing. It was powered by an AC wall socket; it was painful to the patient and is a hazard of electrocution. There were many innovations to this invention that improved the external pacemaker. A pacemaker is used to maintain the regular beat of the heat. While inventing the pacemaker, it gave us a better understanding of the heart and how it beats. By using MRI it gave a better understanding of the human body to create the pacemaker. 

Various technologies gave us a better view of our internal system. By using medical technology, the treatment can by improved and changed to better suit the patient gives us an expand of our knowledge about the human body, thus giving us new ideas and inventions to improve our health. Even though humans are creating a new strain of diseases and sicknesses, medical technology can help to improve the health of the world.
