Show me a diagram of the human heart with a human heart diagram

The heart is a muscular organ that acts like a pump. It sends blood throughout your body continuously. Because of this, the heart is at the center of the circulatory system, and the system is totally dependent on it. The circulatory system consists of a large network of blood vessels that include arteries, veins, and capillaries. These different blood vessels carry blood to and from all areas of your body.

The heart is regulated by an electrical system that uses electrical signals to contract the heart's walls. When a signal causes the walls to contract, blood is pumped into the circulatory system. A system of inlet and outlet valves in the heart chambers work together to ensure that blood flows in the right direction. The human heart is vital to our health and affects everything that goes on in our bodies. Without the heart's regular pumping action, blood cannot circulate within the body.


Blood is vital to our bodies, and carries oxygen and nutrients that our organs need to function normally. Blood also carries carbon dioxide to our lungs. Carbon dioxide is a waste product, and passes from our lungs out of our body and into the air. When our heart is healthy it supplies all areas of our body with the correct amount of blood at the appropriate rate needed for our organs to function normally. If our heart is weakened by disease or injury, our body's organs will not receive sufficient blood to work normally. Following requests to show me a diagram of the human heart, we have provided a human heart diagram below.

The heart is located under the ribcage in the center of our chest between the right and left lungs. Its muscular walls beat, or contract, pumping blood continuously to all parts of our body. The size of a heart can vary depending on our age, size, and it’s condition. Where an adult is normal and healthy, the heart is usually the size of an average clenched adult fist. Sometimes diseases of the heart can cause it to become larger.

The human heart diagram shows the front surface of a heart, including the coronary arteries and major blood vessels.
The heart is the muscle in the lower half of the picture. The human heart has four chambers. These are the right and left atria, which are shown in purple, and the right and left ventricles which are shown in red. Some of the main arteries and veins that make up our blood circulatory system are directly connected to the heart. The right ventricle on the right side of our heart pumps blood from our heart to our lungs. When we breathe air in, oxygen passes from our lungs through our blood vessels and into our blood. At the same time, carbon dioxide, a waste product, is passed from our blood through blood vessels to our lungs and is removed from our body when we breathe out. The left atrium receives blood from our lungs that is rich in oxygen. The pumping action of our left ventricle sends this oxygenated blood through the aorta (a main artery) to the rest of our body.

The Right Side of the Heart
In the human heart diagram the superior and inferior vena cavae are blue in color, and can be found to the left of the heart muscle. These veins are the largest veins in our bodies.When our body's organs and tissues have used the oxygen in your blood, the vena cavae carry the oxygen-depleted blood back to the right atrium of our heart.
The superior vena cava carries oxygen-depleted blood from the upper parts of our body, including our head, chest, arms, and neck. The inferior vena cava carries oxygen-depleted blood from the lower parts of our bodies.The oxygen-depleted blood from the vena cavae flows into our heart's right atrium and then on to the right ventricle. From the right ventricle, the blood is pumped through the pulmonary arteries (in blue in the center of the picture) to our lungs. There, through many small, thin blood vessels called capillaries, the blood picks up more oxygen.The oxygen-enriched blood passes from our lungs back to our heart through the pulmonary veins (seen in red to the left of the right atrium in the diagram).

The Left Side of the Heart
Oxygen-enriched blood from our lungs passes through the pulmonary veins (seen in red to the right of the left atrium in the diagram). It enters the left atrium and is pumped into the left ventricle. From the left ventricle, the oxygen-enriched blood is pumped to the rest of our body through the aorta. Like all of our organs, our heart needs blood enriched with oxygen. This oxygen is supplied through the coronary arteries as blood is pumped out of our heart's left ventricle. Our coronary arteries are located on our heart's surface at the beginning of the aorta. Our coronary arteries (shown in red in the diagram) carry oxygen-enriched blood to all parts of our heart.
