The part of the circulatory system that conveys blood from the heart to the lungs and back to the heart.
The circulation of blood from the heart through the pulmonary arteries to the lungs for oxygenation and back to the heart through the pulmonary veins.
System of blood vessels transporting blood between the heart and the lungs. Deoxygenated blood leaves the right ventricle by way of the pulmonary artery, which divides, sending branches to each lung. The deoxygenated blood gives off its carbon dioxide and takes in oxygen in the alveoli of the lungs. The freshly oxygenated blood is then transported by the pulmonary vein to the left atrium of the heart, where it enters the systemic circulation for transport throughout the body.
A system of blood vessels effecting transport of blood between the heart and lungs. Deoxygenated blood leaves the right ventricle by the pulmonary artery and is carried to the alveolar capillaries of the lungs. Gaseous exchange occurs, with carbon dioxide leaving the circulation and oxygen entering. The oxygenated blood then passes into small veins leading to the pulmonary veins, which leave the lungs and return blood to the left atrium of the heart. The oxygenated blood can then be pumped around the body via the systemic circulation.
The flow of blood from the right ventricle of the heart to the lungs for exchange of oxygen and carbon dioxide in the pulmonary capillaries, then through the pulmonary veins to the left atrium.
Sends the blood from the heart to the lungs to be purified, then back to the heart again.
The pathway that blood follows from the heart to the lungs.
