1 _______.
One product of bioengineering is the artificial heart, which can extend and improve the lives of patients who might die of heart failure while waiting for a transplant of a natural heart. 2 _______. It has electric motors and a pumping system with hydraulic fluid and hydraulic valves. It has external and internal parts (i.e. outside and inside the body). 3 _______. This internal battery is recharged by an external battery using a simple electrical coil, which induces a current. This current then recharges the internal battery. The whole system is controlled by a microprocessor inside the body. Of course, biological safety is very important, so the plastics used in the valves and hydraulic membranes of the artificial heart are durable enough to withstand 100,000 beats of the ‘heart’ per day. 4 _______.
Bioengineering combines biological science with engineering.
This device has been designed to have as few moving parts as possible.
Inside the body is a rechargeable battery which powers the pumping system.
There is also a heart pacemaker, which is implanted under the skin and produces electrical pulses to cause the heart to beat at a regular and reliable pace or speed.
