Question

Read the passage and make notes on it and also give a suitable title. 4 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 musele 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 repalr or replacea defective heart. Msny 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.​

Answer 1

The title of the passage can be set as The Human Heart.

The passage talks about the following topics:

• The human is a vital organ of our body, and it is responsible for the supply of oxygen-rich blood throughout the body.
• The cells of a human heart can live only up to four to five minutes without oxygen. When a heart stops functioning, the whole body stops functioning as well.
• Dr John Gibbon of the USA has invented the machine that can substitute for the heart while surgeons can repair or replace the heart.
• Many people are now kept alive by tiny battery-operated machines in their hearts.
