Heart Structure

Dear All, Today We are going to discus about--

•      Anatomy Physiology of  heart

•      The heart is complex but (looking at the diagram below), you can see there are basically four chambers inside it. The left and right atria are roughly on top and the bigger stronger ventricles are on the bottom.

•      The left and right sides of the heart are divided by a wall - this is called the septum. When it is between the atria, it is called the atrial septum. When it is between the ventricles it is called the ventricular septum. The septum keeps blood from the right and left sides of the heart from mixing. This is important because the blood in the left ventricle is loaded with oxygen for the rest of the body to use. The blood in the right ventricle has already given all its oxygen to the body and needs to be loaded with oxygen again by the lungs. If they mix, the blood sent out to the body will have less oxygen for the body to use.
