Click here to view a larger image. The heart is an organ, about the size of a fist. It is made of muscle and pumps blood through the body. Blood is carried through the body in blood vessels, or tubes, called arteries and veins. The process of moving blood through the body is called circulation. Together, the heart and vessels make up the cardiovascular system.

The heart is an organ responsible for pumping blood through the blood vessels using rhythmic contractions of cardiac muscle. The human heart is the pump for the circulatory system, and along with the circulatory system is considered to be an organ of the cardiovascular system. It consists of four chambers and pumps blood through both systemic and pulmonary circulation to enable gas exchange and tissue oxygenation. The heart is located in the thoracic cavity between the lungs and protected by the rib cage. The heart consists of four chambers separated into two sides. Each side contains an atria which receives blood into the heart and flows it into a ventricle, which pumps the blood out of the heart. The atria and ventricle on each side of the heart are linked together by valves that prevent backflow of blood.

The following information was supplied regarding data availability:. Data is available in the Supplemental Information. It is well known that the pulmonary veins PVs , especially their myocardial sleeves play a critical role in the initiation and maintenance of atrial fibrillation. Understanding the PV anatomy is crucial for the safety and efficacy of all procedures performed on PVs. The aim of this study was to present normal distal PV anatomy and to create a juxtaposition of all PV ostium variants.

A small amount of blood is also drained from the lungs by the bronchial veins. The pulmonary veins course in the intersegmental septa and as such do not run with the bronchi like the pulmonary arteries do. The superior pulmonary veins take an oblique inferomedial course whereas the inferior pulmonary veins run horizontally peripherally before taking a more vertical course. They pass through the lung hilum , antero-inferiorly to the pulmonary arteries, forming a short intrapericardial segment, to drain into the left atrium. The ostia of the inferior pulmonary veins are more posteromedial and the left pulmonary veins being more superior.

Veins are the blood vessels that carry blood to the heart. Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart. This differentiates the pulmonary veins from other veins in the body, which are used to carry deoxygenated blood from the rest of the body back to the heart. Humans have four pulmonary veins in total, two from each lung. There are two right pulmonary veins, known as the right superior and right inferior veins. These carry blood from the right lung. Each pulmonary vein is linked to a network of capillaries small blood vessels in the alveoli of each lung.



Right pulmonary veins

The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins , two from each lung that drain into the left atrium of the heart.,

5 thoughts on “Right and left pulmonary veins

  1. Within the body, there are a total of four pulmonary veins, and all of them connect to the left atrium of the heart.

  2. The pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle of the heart , to the lungs , and returns oxygenated blood to the left atrium and ventricle of the heart.

  3. Mar 23, Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart. This differentiates the.
