The layers of the heart include the pericardium, epicardium, myocardium, and endocardium. The pericardium is the membrane that protects; it is a sac that the heart sits in and has a layer of fluid between for shock and absorption. The epicardium is the first layer of the heart.

The electrical impulse travels through the right atrium and through the Bachmann’s bundle into the left atrium. This stimulates the atria to contract. Next the signal travel to the AV node. The AV node slightly delays the signal. This delay is neededRead MoreAge-Related Changes that Occur in the Cardiovascular System Essay example1192 Words   |  5 Pages Case Study 1 Unit 2: Age-Related Changes that Occur in the Cardiovascular System Slide 1 The title page introducing what subject I am planning on presenting to the residents of the independent living facility.
