Question

A. William Harvey
B. Christian Barnard
C. Har Govindh Khorana
D. Walton Lillehel

Answer 1

The human heart is a muscular organ. Along with blood vessels and blood, the heart forms the human circulatory system. It is also called the blood vascular system. The heart pumps blood that reaches all the tissues in the body through blood vessels. The first heart transplantation was performed by a South African cardiac surgeon in the year 1967.

Complete answer:
We know that the heart constantly pumps blood which supplies the whole body. It consists of four chambers. Upper chambers are called atria and lower ones are called ventricles. Atria is further divided into two chambers by a partition called the interatrial septum and ventricles by the interventricular septum. The heart is derived from the mesoderm. Atria and ventricles of the same side are also divided by fibrous tissue. It is called the atrioventricular septum. In patients having severe cardiac diseases, heart transplantation is the only cure. The process of transplanting the heart from the donor to a patient is called cardiac transplantation. In most of the cases, the donor’s heart is taken from persons who have undergone brain death. The heart is then transplanted to the patient and all the major blood vessels are connected for the proper blood circulation. The first heart transplant surgery was done by a surgeon named Christian Barnard. The heart was transplanted to a person with terminal heart failure named Louis Washkansky. The patient regained full consciousness after the surgery was completed.
Hence, the correct answer is option B.

Note: It was William Harvey who discovered blood circulation. Har Govindh Khorana was a scientist who conducted several studies on nucleic acids and proteins. He gave major contributions in developing the genetic code.
