Editor's Notes
- The heart, the central organ of the cardiovascular system is located between the 2 lungs, in the middle of the chest. While 2/3 lies to the left of the breast bone and 1/3 to the right. If we were to place our hand on our chest, we can feel the heart beat on the left side of the ribcage. Why, because the bottom corner somewhat tilts forward, which is close to the surface of our body.
- The human heart is divided into 4 chambers:1. The Right AtriumThe Right VentricleThe Left AtriumThe Left ventricle.The walls of the chamber is made of a special muscle, called the Myocardium.
- The adult heart is about the size of 2 clenched fists. It is shaped like a cone and weights about 7-15 ounces. The heart is also known as a striated muscle, and the walls of the chambers are made up of the myocardium which contracts rhythmically under stimulation.
- There are three types of blood vessels that exist in the human body:ArteriesVeinsCapillaries
- The cardiovascular system is a great network of the human body, which preforms 2 major task.It delivers oxygen & nutrientsIt removes waste products from tissues cells.
- The Cardiovascular and Lym-pha-tic system is the arterial system
- If you look at your handout on the anatomy of the heart you can get a clear picture of the ins & outs of our heart.

- Veins pump blood to the heart, while arteries pump blood away from the heart..If the heart supplies the blood to the whole of the body, what supplies blood to the heart?The heart takes care of itself first. Frist preservation.
