Bioengineering and Biomedical
A biomedical engineer makes devices to help people treat pain or diseases. They help see what kind of condition you have and help you live a healthier life. These engineers also design medicines.
A project that biomedical engineers are working on are to restore tissues and blood vessels after a heart attack. They have tested this out on pigs.
I found this topic the most interesting because I think its cool that you can see the bones from x-rays and the babies in ultrasounds.
