1 The mitral (MI-trul) valve is in the left side of the heart, between the left atrium and the left ventricle. 2  The aortic (ay-OR-tik) valve is in the left side of the heart, between the left ventricle and the entrance to the aorta. 3  This artery carries blood from the heart to the body.

In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium.

1 The pulmonary (PULL-mun-ary) valve is in the right side of the heart, between the right ventricle and the entrance to the pulmonary artery. 2  This artery carries blood from the heart to the lungs.

Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish in contrast have two chambers, an atrium and a ventricle, while reptiles have three chambers.

The Left Side Of The Heart. Oxygen-rich blood from your lungs passes through the pulmonary veins. It enters the left atrium and is pumped into the left ventricle. From the left ventricle, your blood is pumped to the rest of your body through the aorta.

The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, and also assists in the removal of metabolic wastes.

Although both sides of the heart will pump the same amount of blood, the muscular layer is much thicker in the left ventricle compared to the right, due to the greater force needed here. Like the right ventricle, the left also has trabeculae carneae, but there is no moderator band.

Because the heart is a double pump, each side can fail independently of the other, resulting in heart failure of the right heart or the left heart, either of which through causing strain in the other side can result in the failure of the whole heart.

1 The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body. 2  The coronary arteries are the other important arteries attached to the heart. 3  They carry oxygen-rich blood from the aorta to the heart muscle, which must have its own blood supply to function.

Your child's heart is a muscle about the size of his or her fist. The heart works like a pump and beats 100,000 times a day. The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body.

what wall separates the left side and right side of the heart?
A septum wall separates the left side and the right side of the heart. Septum wall separates the left side and right side of the heart.
