The religion I chose to observe was Jehovah’s Witness‚ they usually hold services two times a week‚ and most of the programs involve audience participation similar to a classroom discussion. Worship beginnings with a song from their “Song Book” which leads to prayer and before ending the service with prayer they sing again. All services focus on reading and discussing the Bible and seeing how to apply it in one’s life. Those in attendance—no matter what ethnic group or age—are encouraged to read

The human heart is slightly bigger than the size of ones fist. It is situated at a very safe place which is between the cage bones‚ i.e.‚ in the center of the chest. Usually it is slightly on the left side of the chest but in rare cases‚ it can be found on the right side. Heart is responsible for the blood flow to every single part of the body by constant contraction and relaxation of cardiac muscles. This is the reason why we hear rhythmic beats all the time. Heart pumps the pure blood to the different

The Human Heart The Human Heart is one of the most important organs in the entire human body. The heart is a muscular organ that acts like a pump to continuously send blood through the body. The heart beats approximately about seventy-two times per minute of our lives. Without the heart’s pumping action‚ blood can’t circulate within the human body. The heart is enclosed in a double walled sac called the Pericardium. The pericardium has outer and inner coats. The outer coat is tough and thickened

transplantation‚ also called heart transplantation‚ has evolved into the treatment of choice for many people with severe heart failure (HF) who have severe symptoms despite maximum medical therapy. Survival among cardiac transplant recipients has improved as a result of improvements in treatments that suppress the immune system and prevent infection.
