Coronary bypass surgery is undoubtedly a very significant achievement of modern
medical science. But one ponders over certain pertinent questions such as the cost involved
and the ultimate benefit.
The human heart is nothing but a four-chambered muscular pump which supplies
blood to all parts of the body. Being an active pump, the heart itself requires a lot of
energy and receives its own blood supply via certain vessels called coronary arteries.
By a process called "atherosclerosis", fat particles are deposited on the inner wall of the
lumen of the coronary arteries which eventually reduce the size of the lumen and produce
obstruction to the free flow of blood. The portion of the heart which suffers from lack
of blood supply becomes weaker as a pump and gives rise to a typical chest pain called
"angina". When such blockage is total, the corresponding heart muscle dies and then one
suffers a "heart attack". In all these circumstances, heart surgeons perform a special type
of operation known as "coronary bypass surgery".
In this surgery a blood vessel is taken (usually from the leg of the patient) and
then grafted on the heart in such a way that when blood flows through, it bypasses the
narrow segment of the diseased coronary artery. The concept is to divert the flow from
the narrow artery, inside which there is already a 'traffic congestion' and in this respect it
is synonymous to road bypass. write a summary of it in a paragraph suggest a suitable title

Answer:
title:- ''Coronary bypass Surgery''
coronary bypass surgery has been one of the greatest achievement in modern medical science. Heart is a pumping machine of the body. the vessels of heart is termed as 'coronary'. excess consumption of fat and cholestrol leads to the blockage of coronary vessels. it is called as atherosclerosis. this arises oxygen deficiency in heart muscles. tissues cries in pain and ultimately die. the pain is called angina. the blockage in the vessels obstructs the free flow of blood which leads to heart attack. in this circumstance a cardio surgeon performs 'coronary bypass surgery' in this vessels from leg is taken and grafted to heart in such a way that blood bypasses thenarrow segment of the diseased coronary artery.
it diverts the flow from narrow artery . in this respect it is synonymous to road bypass.
