What is bland white garland syndrome?

Background: Bland-White-Garland syndrome (BWGS) is a very rare disease characterized by anomalous origin of the left coronary artery from the pulmonary trunk (ALCAPA). WBGS affects 1 in every 300 000 live births. Children typically present with dyspnea, pallor, and failure to thrive.

Is the pulmonary artery a coronary artery?

Normally, the left and right coronary arteries arise from the aorta and supply blood with oxygen to the heart. In children with ALCAPA, the left coronary artery arises from the pulmonary artery and carries blood without oxygen to the left side of the heart.

What carries blood from the lungs to the heart?

Pulmonary veins: The veins do the opposite job of pulmonary arteries and collects the oxygenated blood and carry it from the lungs back to the heart. The veins merge into larger veins. Each lung has two pulmonary veins that deliver blood to the heart’s top left chamber or atrium.

Why is the pulmonary artery different from other arteries?

Structure. The pulmonary arteries are blood vessels that carry blood from the right side of the heart through to the capillaries of the lungs. The blood that is carried is, unlike other arteries, without oxygen (“deoxygenated”).

Which structure carries blood to the heart so the heart has its own supply of oxygen?

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

Which blood vessels have the thinnest walls?

Capillaries – Enable the actual exchange of water and chemicals between the blood and the tissues. They are the smallest and thinnest of the blood vessels in the body and also the most common. Capillaries connect to arterioles on one end and venules on the other.

What are the 4 chambers of heart?

The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.

Which vein is the only vein that carries oxygen-rich blood?

pulmonary veins
The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.
