Question

Q.3 Read the passage and make notes on it and also give a suitable title.

The heart is one of the most vital components of the human body. The heart of the human body has the continuous job to keep oxygen-rich blood flowing through the body. All the body's cells need a constant supply of oxygen, particularly in the brain. The brain cells live only four to five minutes after the oxygen is cut off and death comes to the entire body. Heart disease can result from damage to the heart muscles, the valves or the pacemaker. If the muscle is damaged, the heart is unable to pump properly. If the valves are damaged, blood cannot flow normally. Dr John Gibbon of U.S.A. developed a machine in 1953 that could take over temporarily from the heart. Surgeons had the chance to repair or replace a defective heart. Many patients have had plastic valves inserted in their hearts when their hearts were faulty. Many people are now being kept alive with tiny battery operated pacemakers.​

                                      The Human Heart

• Human heart's aim is to maintain oxygen-rich blood circulating throughout the body continuously.
• A continuous supply of oxygen is needed. If it is cut off, brain cells only exist for four to five minutes until the entire body dies.
• Damage to heart muscles, valves, or pacemakers can cause heart disease.
• Dr. John Gibbon devised a device that could temporarily replace the heart. There was an option to repair/replace a damaged heart.
• When patients' hearts were defective, plastic valves were implanted in their hearts.
